Description |
An experiment was conducted during 2003 and 2004 to study the nature and magnitude of genetic parameters and its utilization in development of superior genotypes of clusterbean [Cyamopsis tetragonoloba (L.) Taub]. Genetic parameters, viz genetic co-efficient of variation, phenotypic co-efficient of variation, heritability (h2) and genetic advance were calculated for seed yield and yield attributing components in 42 diverse genotypes of clusterbean. Characters, like seed yield/plant, biological yield, number of branches/plant and plant height exhibited considerable magnitude of genetic co-efficient of variation (>20%) along with high estimates of heritability indicating that phenotypic per se selection improvement of these traits could be brought about by simple methods. Though 100-seed weight had the highest phenotypic correlation with seed yield/plant, but its direct contribution was negligible. However, it showed significant effect on seed yield/plant via plant height (0.38), branches/plant (0.26) and biological yield (0.15). Path co-efficient analysis revealed that the seeds/pod and pods/plant had highest direct effect on seed yield/plant.
