Manifestation of genetic variability and correlation studies in seedling trees of walnut (Juglans regia L.)

摘要

The nature and magnitude of genetic variability and correlation studies was assessed in 20 seedling trees of walnut for kernel and nut characters. The phenotypic and genotypic coefficients of variation were almost identical in expression for these characters. Likewise, the high heritability and high genetic advance were also reported for nut yield/plant and shelling percentage. However, genotypic and phenotypic correlations for important component traits were also significant with each other. Direct and indirect contribution of independent variables on dependent variable is also reported for the crop.
