摘要

The study of distribution properties such as coefficients of skewness and kurtosis provides insight about the nature of gene action and number of genes controlling the traits respectively. They are more powerful than first and second degree statisticswhich reveal interaction genetic effects. The objective of present investigation to know the genetics of yield and and yield attributes using smaller (622 accessions) and manageable sub sets (known as core collections) which capture maximum variabilityof the entire global collections (5949 accessions) has been developed in finger millet. Quantitative traits seldom had relationship with any of the morphological traits such as grain colour, plant pigmentation and nature of ear head and geographical origin. The pattern of distribution suggested involvement of an excess of dominant genes with complementary or duplicate epistasis in the inheritance of most of the traits.
