    Notes: Summary Tests of parents and F1, F2 and F3 generations of crosses of JG-62 (early-rilting) and C-104 (late-wilting) with resistant cultivars provide further evidence that resistance in chickpea (Cicer arietinum L.) to Race 1 of Fusarium oxysporum f.sp. ciceris is controlled by at least two genes, both of which must be present in homozygous recessive form for complete resistance. Singly, one of the genes delays wilting, as in C.104. The second has not yet been isolated but crosses of resistant parents with JG-62 suggest that it operates in similar fashion.

    Inheritance and linkage of a gene for resistance to race 4 of fusarium wilt and RAPD markers in chickpea (1998)

    Notes: Abstract Several races of Fusarium oxysporum Schlechtend.:Fr f. sp. ciceris (Padwick) Matuo and K. Sato cause economic losses from wilting disease of chickpea ( Cicer arietinum L.). While the genetics of resistance to race 1 have been reported, little is known of the genetics of resistance to race 4. We undertook a study to determine the inheritance of resistance and identified random amplified polymorphic DNA markers (RAPDs) linked to the gene for resistance. For the investigation, we used 100 F5 derived F7 recombinant inbred lines (RILs) that had been developed from the cross of breeding lines C-104 x WR-315. Results indicated that resistance is controlled by a single recessive gene. The RAPD markers previously shown to amplify fragments linked to race 1 resistance also amplified fragments associated with race 4 resistance. The RAPD loci, CS-27700, UBC-170550 and the gene for resistance to race 4 segregated in 1:1 ratios expected for single genes. Both RAPD markers were located 9 map units from the race 4 resistance locus and were on the same side of the resistance gene. Our results indicated that the genes for resistance to race 1 and 4 are 5 map units apart. The need to determine the genomic locations of race specific resistance genes and the possibility that these genes are clustered to the same genomic region should be investigated.

    Direct and indirect selection for yield in chickpea (1992)
    Springer
    Euphytica 60 (1992), S. 197-199 
    Details
    ISSN: 1573-5060
    Keywords: Cicer arietinum ; chickpea ; selection ; yield
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary The efficiency of indirect selection for seed yield was compared with direct selection for yield per se in chickpea. A total of 2500 single F2 plants, derived from 50 crosses with 50 plants from each cross, were divided into five sub-populations (SP1 to SP5) of 500 plants each by including 10 plants from each of the 50 crosses. The five sub-populations were advanced upto F6 by exercising 10% selection intensity for four successive generations for number of pods per plant in SP1, number of seeds per pod in SP2, seed weight in SP3, seed yield in SP4 and random selection in SP5. The efficiency of direct and indirect selection for yield was evaluated by comparing groups of 50 F6 lines from each sub-population. SP1 and SP3 F6 lines showed higher mean grain yield than the other three methods. SP1 and SP3 were found to be almost equally efficient in developing F6 lines which were significantly superior to the check. This suggests that indirect selection for yield via pod number and seed weight is more efficient than direct selection for yield.
