Abstract:

The analysis of genetic diversity using D2 statistics clustered 33 selected genotypes of cultivated finger millet into ten different clusters. The cluster I had 8 genotypes and cluster II and IV had 9 genotypes each. The remaining clusters had only one genotype each. The inter cluster distance was highest (D=46.61) between cluster VII (GE4568) and cluster VIII (GE1200) and between cluster VII (GE4568) and cluster II (D=42.22). The trait days to 50 per cent flowering contributed more towards the genetic divergence of 33 selected finger millet genotypes. The cluster VII having solitary genotype GE4568 had the highest cluster mean value for grain yield per plant, total ear head weight per plant, main ear head weight and shoot dry weight. Similarly, cluster III having solitary genotype GE5118 had the highest cluster mean value for plant height, main ear head length, finger length and finger width. The genotypes GE4568 and GE5118 were emerged as most divergent genotypes with higher mean per se performance for many of the yield and yield related traits, which can be effectively utilized in hybridization programme to generate highly variable segregating population to complement all the seed yield and yield related traits to produce superior cultivar.
