Abstract:

Finger millet is an important millet crop known for its three-fold security. The present study was undertaken to assess the associations among various traits and diversity amid 29 finger millet genotypes. All genotypes were evaluated for grain yield, yield components and disease traits at Agricultural Research Station, Vizianagaram, Andhra Pradesh. Association analysis of 14 traits revealed significant positive association between phenological traits and grain yield. It was also observed that longer ears tend to have higher grain yields. The variability of 14 traits was majorly captured by the first principal component where the phenological traits, disease traits and grain yield contributed higher percent compared to others. These traits can serve as reliable selection indices for improving yield potential and adaptability in finger millet breeding programs. Circle plot was also in agreement with association analysis that days to 50% flowering (DFF), days to maturity (DM), ear length (EL), and finger length (FL) were positively associated. Further, the biplot helped to view the grouping of various genotypes into clusters.
