Estimation of Heterosis, Heterobeltiosis and Economic Heterosis in Dual Purpose Sorghum [Sorghum bicolor (L.) Moench]

General and specific combining ability in dual purpose sorghum [Sorghum bicolor (L.) Moench]

“…Therefore, developing dual purpose and early genotypes tester T3 could be identified. Similar results were found by Indhubala et al, (2010) [12] Salunke and Deore (2000) [23] , Ravindrababu et al, (2001) [22] Bahadure et al, (2015) [2] , Meena et al, (2017) [17] and Iyanar et al, (2001) [11] , Leonilo et al, (2020) [15] , also identified lines with good GCA effects for grain yield along with other attributes. SCA along with GCA is essential for taking the decision about breeding methodology.…”

Stability Analysis in Dual Purpose Sorghum [Sorghum bicolor (L.) Moench]

“…For other two crosses L 2 x T 3 and L 6 x T 3 the S 2 d i was significant this indicates instability for plant height and ear head length in crosses L 2 x T 3 and L 6 x T 3 therefore these hybrids may be tested under wider range of environmental condition with more control to reduce the error variance between the environments. Similar results i.e., non significant S 2 d i and identification of genotypes on the basis of b i for one or more characters were also obtained by Palanisamy and Prasad, (1980), Dangi et al, (1980), Desai and Deore (1980, Singh and Nayeem (1980, Meena et al, (2017) Shahane andBapat (1981) Patil et al, (1991) and Prabhakar and Patil (2002). Two crosses L 2 x T 3 and L 6 x T 3 having economic heterosis more than 15 per cent for grain yield and dry fodder yield, good SCA, involving one good GCA parents, nicking in flowering in normal spacing environment and male parent taller than the female parent are identified to contribute in the coordinated trials for multilocation testing.…”
