Genetic divergence study for duration and biomass traits in sorghum [Sorghum bicolor (L.) Moench]
Germplasm can be exploited efficiently by determining its genetic diversity and identifying desirable parents for crop improvement programs. In this study, 200 diverse sets of sorghum accessions were evaluated during rabi, 2019 with an aim of assessing genetic diversity for fodder component traits using D2 statistics. Fresh biomass contributed the highest (47.4%) towards divergence followed by days to flowering (35.9%) and plant height (16.7%). All the 200 genotypes were grouped into 6 clusters with Cluster I having the maximum number of genotypes (108) followed by cluster IV (47), VI (39) and clusters II, III, V having the least genotype number (2). Cluster I had the highest (10.61) intra cluster distance while cluster II had the least (0.41) intra cluster distance. Inter cluster distance between I and IV was observed the highest (10.43) while the least was observed between III and V. Genotypes from Cluster II and IV were observed to be the best suited for fodder improvement programs.
