Abstract:
The genetic investigation was carried out line x tester design for heterosis analysis studies the experimental material comprised with line x tester (4 x 23) and their parents. Several hybrids exhibited heterobeltiosis and standard heterosis for seed yield per plant and other characters. The hybrids viz., GDM-4 x EC-766443, GDM-4 x EC-766060 and GDM-4 x EC-766558 were found promising for commercial exploitation of heterosis as they showed maximum standard heterosis. Multilocation evaluation is required before commercial cultivation. On the basis of estimates of heterobeltiosis and standard heterosis hybrids viz., GDM-4 x EC-766043 and GDM-4 x EC-766434 respectively, found to be most promising for seed yield per plant and other desirable traits, hence could be further evaluated to exploit the heterosis or utilized in future breeding programme to obtain desirable segregants for the development of superior genotypes.
