    Genetic mapping of new morphological, isozyme and RAPD markers in Vicia faba L. using trisomics (1996)
    Springer
    Theoretical and applied genetics 93 (1996), S. 1130-1138

    ISSN: 1432-2242

    Thema: Biologie
    Notizen: Abstract Thirteen F2 families of faba bean (Vicia faba L.), descended from plants trisomic for chromosomes 3, 4, 5 and 6, have been analyzed for morphological, isozyme and RAPD markers. This allowed the establishment of linkage relationships among these markers as well as the assignment of some markers and/or linkage groups to their respective chromosomes. The linkage analysis of partially overlapping sets of informative genetic markers for the data pooled from 13 F2 families has revealed 48 linkage groups, six of which have been precisely assigned to specific chromosomes. A statistical procedure to analyze the data of joint segregation analysis in families derived from trisomic plants has been developed.

    Quantitative inheritance and barriers to crossability in Cicer arietinum L. (1979)
    Springer
    Theoretical and applied genetics 55 (1979), S. 5-16 
    Details
    ISSN: 1432-2242
    Schlagwort(e): Genetic barriers ; Cicer arietinum ; Diallel analysis
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie
    Notizen: Summary Three different diallel crosses were studied in Cicer arietinum; two of size 6×6, one within each of the two botanical groups ‘macrosperma’ and ‘microsperma’ of the cultivated subspecies, and one of 9×9 involving lines covering most of the morphological variation of chickpea. Barriers to crossability present neither a botanical nor a geographical pattern, being probably a direct consequence of interactions between genotypes. The genetic systems of twelve quantitative characters were analysed. Full dominance in a negative sense (small values dominant) is shown by leaflet length, width and shape index, rachis length, leaflet density on the rachis and pod length. Full dominance in a positive sense is shown by seeds per pod. Overdominance (in a positive sense) is evident for pods, seeds and yield per plant. Weak reciprocal differences were manifested by pod length, and pods, seeds and yield per plant. The system controlling number of leaflets per leaf is not clear. Dominance of ‘primitive’ over ‘selected’ characters seems to be the rule. As far as the environmental effects have permitted the analysis, no differences in genetic systems were observed between botanical groups.

    Variation in Cicer arietinum L. (1978)
    Springer
    Euphytica 27 (1978), S. 465-485 
    Details
    ISSN: 1573-5060
    Schlagwort(e): Cicer arietinum ; chickpea ; biosystematics ; intraspecific variation ; crop evolution ; phenotypic ; genotypic and environmental correlations ; principal component analysis

    Thema: Land- und Forstwirtschaft, Gartenbau, Fischereiwirtschaft, Hauswirtschaft
    Notizen: Summary A collection of populations and cultivars of Cicer arietinum L. were studied to obtain phenotypic, genotypic and environmental correlation coefficients, and broad sense heritabilities. Principal Component Analyses were performed on phenotypic, genotypic and environmental matrices. Data and phase obtained on a pure morphological basis, as well as on quantitative genetic studies and geographical distribution support the existence of two complexes within the cultivated chickpea, macrosperma and microsperma. These taxa differ in a cluster of complex characters associated with seed. pod and leaf morphology, and they differ in distribution. There is no taxonomic basis to treat these as subspecies. We propose to include C. reticulatum Lad., the wild chickpea, as a subspecies of C. arietinum, with the cultivated kinds recognized as subspecies arietinum. Race macrosperma was derived from race microsperma through selection during relatively recent times of the evolutionary history of the chickpea.

    Phenotypic, genotypic and environmental correlation in tomato (Lycopersicon esculentum) (1982)
    Springer
    Euphytica 31 (1982), S. 151-159 
    Details
    ISSN: 1573-5060
    Schlagwort(e): Lycopersicon esculentum ; tomato cultivars ; phenotypic ; genotypic and environmental correlations ; indirect selection
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Land- und Forstwirtschaft, Gartenbau, Fischereiwirtschaft, Hauswirtschaft
    Notizen: Summary Twelve inbred lines of tomato and their 132 hybrids (reciprocals were considered separately) were studied in four environments: glasshouse and open air, with and without plastic cover. Nine characters were recorded and the phenotypic and environmental correlations between them were obtained within environments and for the complete set of data. Characters showing the highest phenotypic correlation with yield were fruits per cluster and earliness in harvesting, but neither of them is useful for indirect selection for yield. To the contrary, leaves between racemes can be used when selecting for fruits per cluster. Environmental correlations were generally low, excepting total yield in fruits per cluster. Broad sense heritabilities were obtained, which were rather high for fruit weight, locules per fruit, fruits per cluster and leaves between clusters. Some cases in which phenotypic correlations were rather constant for the different environments in spite of the great differences recorded for the genotypic correlation coefficients, are explained because of the great weight (i.e., considering heritabilities) of environmental correlations on phenotypic correlations.
