Unraveling the genetics of trait associateship and nutrient significance of determinate horse gram mutants
Horse gram is a nutrient-rich and photo-sensitive legume crop. The experiments were carried out to study the association among traits in horse gram. A total of six determinate and photo-insensitive horse gram mutants were raised in RBD with five replications in two locations in all three seasons (Kharif’22, Rabi’22 and Summer’23), and the mean data for ten quantitative traits were subjected to correlation and path analyses. The findings of correlation analysis indicated that the traits number of clusters per plant and number of pods per plant had a positive association with seed yield per hectare. Similarly, the path analysis revealed that the number of pods per plant and hundred seed weight exhibited a positive and direct effect on seed yield per hectare. There was a noticeable variation observed for both macro and micronutrients. From the current experiment, two determinate mutants TNAU-HG-DM-004 and TNAU-HG-DM-001 were selected as nutrient-rich genotypes with high yield potential. Hence, these determinate mutants can be used as donors for yield as well as nutrient improvement programs in horse gram.
