    Notes: Summary Unfertilized and NPK-fertilized plots in the long term fertility trial at Los Baños, Philippines were used to observe the effect of nitrogen fertilizer on heterotrophic N2-fixing activities in plow layer soil and in association with wetland rice. The activities were measured in the field byin situ acetylene reduction assays. Acetylene reduction activity of the plow layer soil in the paddy field was measured by soil cores. No appreciable difference was found-between fertilized and unfertilized plots.

    Notes: Summary A greenhouse experiment was conducted to study the effect of phosphorus and zinc application, in three lowland alluvial rice soils (Haplustalf) on the growth of rice and the concentration of phosphorus, zinc, copper, iron and manganese in shoots and roots. The results showed that application of phosphorus and zinc significantly increased the dry matter yield of shoots, grains and roots. Application of phosphorus caused a decrease in the concentration of zinc, copper, iron and manganese both in shoots and roots. Application of zinc also similarly lowered the concentration of phosphorus, copper and iron, but increased that of manganese in shoots and roots. The decrease in the concentration of the elements in the shoots was not due to dilution effect or to the reduced rate of translocation of the elements from the roots to tops. This has been attributed more to the changes in the availability of the elements in soil resulting from the application of phosphorus and zinc.

    Notes: Summary The effect of N and Zn on the yield of submerged rice and uptake of N and Zn was studied on limed and unlimed soils in greenhouse. Nitrogen was applied at the rate of 0,80 and 160 ppm through urea, ammonium sulphate and ammonium nitrate, Zn at 0 and 10 ppm in limed (4% CaCO3) and unlimed soils. Liming (4% CaCO3) decreased dry matter yield of rice at tillering, heading and straw and grain at maturity significantly against unlimed treatments. Ammonium sulphate gave highest yield with all applied doses followed by ammonium nitrate and urea. Zinc at 10 ppm increased dry matter and grain yield significantly over no Zn treatment in rice. The N sources gave N concentration and uptake in rice plants in decreasing order: $$Ammonium sulphate 〉 Ammonium nitrate 〉 Urea.$$ The highest N concentration was recorded with 160 ppm followed by 80 ppm N through any source and lowest in control. The application of Zn increased and liming decreased N concentration and uptake by rice at all sampling stages. Highest N concentration (2.37 to 3.92%) was observed at tillering followed at heading (0.48 to 1.05%). At maturity N in grain ranged from 0.69 to 1.13% whereas in straw from 0.24 to 0.41%. There were positive significant interactions of N(S) x N(L), N(S) and N(L) x Zn and negative interaction with lime on yield, N concentration (%) and N uptake (mg/pot). The application of N sources and levels and Zn increased Zn uptake (μg/pot), and liming decreased it. But 160 ppm N through any source decreased straw Zn concentration over 80 ppm N in absence of added Zn, however, effects on grain were not so strong particularly that of 160 ppm, when 10 ppm Zn was also added even 160 ppm N increased Zn concentration over 80 ppm significantly in both straw and grain. In this case the effect of N sources on Zn concentration was in the order: $$Ammonium sulphate 〉 Urea 〉 Ammonium nitrate.$$

    Notes: Summary The effects of Zn, P, N and CaCO3 on tryptophan concentration in rice grain were studied in greenhouse at Haryana Agricultural University. Zinc application upto 20 ppm increased tryptophan concentration in rice grain. Zn-EDTA gave highest increase followed by ZnSO4 and then ZnO. Liming at the rate of 4 and 8 per cent decreased tryptophan concentration significantly. Phosphorus application upto 100 ppm also decreased tryptophan significantly but Zn in combination with P increased tryptophan and overcame negative effect of P. Nitrogen application upto 120 ppm increased tryptophan concentration. There was positive interaction between Zn and N. Ammonium sulphate gave highest tryptophan followed by ammonium nitrate and then urea. The tryptophan concentration ranged between 766 ppm and 2011 ppm in paddy grain. The lowest tryptophan concentration was in the plants treated with 8 per cent lime in absence of added Zn and highest with 10 ppm Zn through Zn-EDTA.

    Notes: Summary The utility of spraying some known N2-fixing microorganisms on rice leaves grown both in N-less sand culture and under field conditions was examined. The effect was compared with that of spraying a phyllosphere N2-fixing isolate of Klebsiella, KUPBR2, and application of nitrogenous fertilizers. All the growth parameters studied including dry weight and N-content were enhanced. Under field conditions number of tillers was increased by 26% withKlebsiella pneumoniae M5al and by 65% with Aphanothece. The dry weight of the plants was enhanced by 61–119%. The yield per 10 m2 was almost doubled with Aphanothece, Beijerinckia 8007,Mycobacterium flavum, K. pneumoniae M5al and KUPBR2. The increases observed withStreptomyces sp. G12 though less spectacular was significant at 1% level with respect to several growth parameters.K. pneumoniae M5al,M. flavum andStreptomyces sp. G12 exhibited nitrogenase activity both in laboratory culture and in association with rice plants.

    Inheritance of salt tolerance in rice (1981)

    Notes: Summary The genetic behavior of salt tolerance was studied in artificially salinized conditions at the International Rice Research Institute. Divergent selection, carried out at a salinity level where the ECe was 15.2 mmhos/cm at 25 C in F3 lines from two crosses confirmed the effects of salt tolerance on F4 progeny with realized heritability values of 0.39 and 0.62, respectively. In a cross between two tolerant cultivars there was clear over-dominance for tolerance, despite the high environmental fluctuation which resulted in a low genetic response as indicated by a low but significant repeatability of 0.20–0.25, and many progeny lines more tolerant than the parents were recovered. The superior tolerance of these progenies compared to the parents was confirmed subsequently at 3 different salt levels. In the same experiment a cross between tolerant and susceptible cultivars produced some progeny of comparable tolerance with tolerant sources. In a 6×6 diallel cross experiment with two tolerant, moderate, and susceptible varieties each, both general and specific combining ability were significant. The findings indicate the possibility of breeding rices more tolerant than existing tolerant cultivars through cumulative crosses of tolerant cultivars. Further improvement can be attained by crossing highly tolerant lines with donors of good agronomic traits and pest and disease resistance.

    Notes: Summary A preliminary investigation on the inheritance of tolerance to Zn deficiency and the inter-relationship of tolerances to Zn deficiency and alkalinity was made. Three generations of 2 crosses involving parents tolerant (IR20 and IR30) and sensitive (E425) to Zn stress were screened in IRRI concrete beds. One hundred genotypes (varieties and breeding lines) were screened for injury from alkalimity and Zn deficiency. The results of this experiment and earlier mass screening experiments were subjected to association analyses. The results in general indicated that tolerance to different mineral stresses behave nearly independently. The frequency distribution of ratings for 3 generations indicated that the trait tolerance to Zn deficiency is under polygenic control showing continuous variation and transgression in F2. Tolerance seems to be dominant. The heritability varied between crosses.

    Notes: Summary Factors favouring callus proliferation and subsequent regeneration of plants from pollen grains of rice anthers (Oryza sativa L., cvx. Bahia, Girona, Balilla × Sollana and Sequial) were determined. Cultivar differences in response were found, such as a high rate of haploid plant regeneration. In addition, isolated pollen grain culture was used to induce tissue proliferation outside the anther walls. The frequency of callus formation from isolated pollen grains was very low. It was necessary to preculture the anthers before pollen grain separation, in order to accomplish a successful development later. Root differentiation was observed in some of the obtained callus.

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary In common rice, Oryza sativa L. (n=12), the gene Am for ‘non-glutinous’ is dominant over the gene am for ‘glutinous’. In African rice, O. glaberrima Steud. (n=12), no spontaneous glutinous strain has been found, but recently a glutinous strain of glaberrima was induced by EMS-treatment. The interspecific cytoplasm substitution line with sativa cytoplasm and glaberrima nucleus is male sterile. It has been confirmed that the complete restoration of pollen fertility in this male sterile line is attributed to a single dominant nuclear gene Rf j.Trial to transfer gene am from sativa to glaberrima was commenced with backcrosses of the F1 hybrid (glutinous sativa cv. Iwai-mochi ♀ × glaberrima ♂) to glaberrima type plants of the substitution line homozygous for Rf j,using the latter as the pollen parent. At the B1 step, highly fertile glaberrima type Am/am plants were obtained. Thereafter plants of this type were backcrossed to normal glaberrima as the recurrent pollen parent to complete the nuclear substitution. It was confirmed that the EMS-induced glutinous character of glaberrima was a monogenic recessive and that the same gene controls the expression of glutinous character in the different rice species, sativa and glaberrima.

    Notes: Summary Drought is a constraint to rice yields in much of Asia's rainfed rice crop. Although genotypic variation for root system characteristics is well documented in this semiaquatic species, little improvement of rice for drought resistance has been attempted. No simple method to evaluate root systems exists. In this paper we report the development and testing of a simple device to measure the pulling force required to uproot rice seedlings. The force required to pull rice seedlings from the paddy soil was correlated with root weight, root branching and thick root number. The capability to separate rice cultivars by this technique and relationship of the root pulling force to other drought screening methods are illustrated.

    Notes: Summary The cross of two indica types of rice T9 and M35, provided scope for the inheritance study of 16 characters such as flowering, awning and awn colour, panicle density and panicle exsertion, presence of ligule, bent node, and pigmentation in ten other characters. Besides the purple colour, yellow and chalky white were studied for their inheritance. Two to five pairs of factors were found to govern the 16 characters under study. Complementary, duplicate, complementary duplicate, inhibitory complementary and inhibitory duplicate action of genes was observed. Independent dominant action of individual genes which is equivalent to the action of two or three genes is recorded in respect of panicle density and awning and awn colour. Inheritance of the 16 characters shows the involvement of 59 genes unreported in the past. Out of them 19 are inhibitors. Combined segregation data have revaled the existence of many pleiotropic genes acting on two or more characters and exhibiting differential expression in some of them, which is an interesting part of the present study. Linkage analysis has resulted in the assignment of the record number of 17 genes to a single group, nine of them being inhibitors. The linkage map constructed in the order of genes as suggested by the cross over values shows a good agreement. This linkage group is concluded not to form part of any group propounded by Misro et al. (1966) in indica rice.

    Notes: Summary The inheritance of anthocyanin pigmentation and the interrelationship between genes governing anthocyanin pigmentation in different parts of the rice plant and genes governing panicle density were studied in the cross Suma × Wanar-1. A ratio of 45 pigmented: 19 non pigmented was realised for anthocyanin accumulation in sheath, nodal ring, internode, leaf tip, leaf margin and apiculus whereas a ratio of 3 normal:1 laxy was observed for panicle density. Pleiotropic action of a basic gene (A) and each of the two complementary duplicate genes (P a or P b) was detected. A linkage group of genes localising pigment in six plant parts was identified, the sequence of genes being P nr-P lm-P la-P a-P sh-P in. This may form part of the III ‘S p’ group of Misro et al. (1966), in which case the genes P nr and P la are proposed to be additions to this group.

    Notes: Summary Effects of water table depths on plant-water status, and on growth and yields of two rice varieties (TOS 78 and TOS 848) were studied in a lysimetric investigation. A field study was also conducted on a hydromorphic soil to investigate the effects of fluctuating water table on rice. The leaf-water potential of TOS 78 monitored at 1300 hours at 50% flowering stage was −17.5 and −23.0 bars for 0 and 60 cm water table depths, respectively. When grown under soil moisture stress, TOS 848 maintained higher leaf-water potential (−17.5 barvs −22.5 bar) and yielded more than TOS 78. Under hydromorphic soil conditions, no-tillage treatments yielded the same as conventionally tilled plots.

    Notes: Summary Studies on the nature of relationship between grain size (in terms of thousand grain weight), grain number, rate of filling and yield have been worked out with late duration (140–150 days) rice varieties. Grain number per m2, grains per panicle and yield showed a negative relationship with grain size. There was no compensatory balance between grain size and grain number within a range of thousand grain weight of 15 to 30 g. Based on the peaks in grain filling activity, the varieties were classified into four groups. There was no relationship between grain size and rate of grain filling thereby suggesting that grain filling is determined by inherent endogenous factors.

    Notes: Summary Because zinc deficiency is a widespread disorder of wetland rice and copper deficiency may occur with it, 0.05M HCl was compared with 0.1M HCl, EDTA and DTPA as an extractant for available zinc and copper. It was also compared with the reflux method for boron assay. Thirty-three wetland rice soils were analyzed for zinc and copper by the four methods. Rice was grown on the flooded soils, scored visually for zinc deficiency, and the plants analyzed for zinc and copper content. In the boron study, 53 soils were extracted by the reflux method and the 0.05M HCl procedure. Rice was grown on the flooded soils, scored visually for boron toxicity, and the plants analyzed for boron content. Fourteen of the 16 soils on which rice showed zinc deficiency gave 〈1.0 mg/kg Zn by the 0.05M HCl method but values far in excess of the critical limits by the other methods. The r values for available and plant zinc were: 0.05M HCl (0.88**); 0.1M HCl (0.55**); EDTA (0.43**); and DTPA (0.31ns). Twelve of the zinc-deficient soils gave〈0.1 mg/kg Cu by the 0.05M HCl method but values exceeding the critical limits by the EDTA and DTPA methods. The r values for available and plant copper were: 0.05M HCl (0.74**), 0.1M HCl (0.64**), EDTA (0.28ns), and DTPA (0.20ns). The critical limit of 1.0 mg/kg by the 0.05M HCl extraction was confirmed for zinc deficiency and a tentative value of 0.1 mg/kg for copper deficiency proposed. The 0.05M HCl method separated boron-toxic soils from non-toxic soils and gave a better correlation (r=0.91**) between available and plant boron than the reflux extraction (r=0.84**). The toxic limit by the 0.05M HCl method was provisionally set at 4 mg/kg.
