    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

    Notes: 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.

    Variation in Cicer arietinum L. (1978)
    Springer
    Euphytica 27 (1978), S. 465-485 
    Details
    ISSN: 1573-5060
    Keywords: Cicer arietinum ; chickpea ; biosystematics ; intraspecific variation ; crop evolution ; phenotypic ; genotypic and environmental correlations ; principal component analysis
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: 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
    Keywords: Lycopersicon esculentum ; tomato cultivars ; phenotypic ; genotypic and environmental correlations ; indirect selection
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: 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.
