Exploitation of heterotic combinations for grain yield and yield associated components in Kharif Sorghum

An investigation was done to estimate magnitude of heterosis in sixty six hybrids (F1’s) of Sorghum (Sorghum bicolor (L.) Moench) with respect to yield and its associated components using six newly developed (CGMS) lines and eleven testers. The resulted 66 hybrids and their 17 parents along with two standard checks (CSH 14 – for earliness and CSH 35 – for yield) were evaluated to assess magnitude of heterosis, heterobeltiosis and economic heterosis by using line × tester analysis at Sorghum Research Unit, Dr. P.D.K.V. Akola 444 001, Maharashtra during Kharif 2015-16.
