ABSTRACT
This study was initiated in finger millet with the prime objective of formulating suitable selection index using inverse of means as their respective economic weights for simultaneous selection of different quantitative and nutritional traits viz., Seed calcium content, seed protein content, plant height, days to 50% flowering, days to maturity, number of productive tillers per plant, fingers per ear, finger length, ear weight per plant, 1000-seed weight, and seed yield per plant. It was observed that addition of characters one by one in the construction of selection index resulted in the increased estimates of genetic advance. Finally the index constructed using all the eleven characters, recorded maximum expected genetic advance and percent gain over seed yield per plant compared to all 2047 possible combinations. From this it became evident that the best possible construct in case of finger millet for selecting superior genotypes should include maximum number of characters that are considered for investigation.
Key words: Selection Index, Economic weights, Inverse of Means, Finger millet.
