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 statistics which reveal interaction genetic effects. The objective of present investigation to know the genetics of grain macro and micro nutrients contents in mini core germplasm collections of finger millet. Assessing and exploitation of existing variability among germplasm accessions is the first principle of breeding micronutrients and protein-dense finger millet cultivars. The results revealed substantial variability for grain nutrient contents. Most of the grain nutrient contents appear to be inherited by an excess of dominant genes with duplicate epistasis. Accessions contrasting for grain nutrients contents have been identified. These results are discussed in relation to breeding and selection strategies required for genetic enhancement of grain nutrients contents 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.
