Abstract


Rabi sorghum hybrids developed using 104A, 116A (milo) and M31-2A (maldandi) as females and nine fertility restorers were evaluated for yield and its components. The milo (104A and 116A) hybrids showed increased panicle length and number of grains per panicle in comparison with maldandi (M31-2A) hybrids. The maldandi (M31-2A) hybrids revealed moderate height, increased number of leaves, intermediate flowering and more seed weight when compared to milo (104A and 116A) hybrids. Milo hybrids exhibited superiority over maldandi hybrids for most of the characters in desired direction. Restorers SPV 1090, Barsi prakash and GRS1 recorded desirable general combining ability (gca) effects for important traits. Among the 104A (milo) hybrids viz., 104A x GRS1, 104A x IUS 177 recorded higher per se grain yield, positive heterosis and sca effects, while among the 116A (milo) hybrids viz., 116A x Barsi prakash and 116A x IUS 177 recorded higher per se grain yield, positive heterosis and sca effects. New milo-based lines could be exploited for the development of rabi sorghum hybrids by identifying suitable restorers on them. Good restorers for maldandi lines could also be identified and exploited in hybrid development programme.
