Field experiment was carried out at experimental field of Sorghum Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth (PDKV), Akola to identify the promising early lines and testers along with desirable grain yield in sorghum. Newly developed six cytoplasmic male sterile lines (CGMS) lines and eleven testers were crossed in line x tester fashion and the resultant 66 hybrids were evaluated along with the checks (CSH 35 for grain yield and CSH 14 for earliness) and parents for days to 50% flowering, days to maturity and grain yield per plant under combining ability analysis during Kharif 2015. The results of general combining ability analysis revealed that among the lines, two promising lines AKMS 89A and AKMS 103-8-1A found early on the basis of general combining effects (gca) for days to 50% flowering (-2.34** and -1.40** respectively), days to maturity (-0.96** and -0.57** respectively) and with desirable grain yield per plant (4.10** and 5.19** respectively). Similarly, among the testers, the tester AKR 524 and AKR 528 were found to be the good general combiners for grain yield (3.04*, 2.64*) along with earliness like early days to 50% flowering (-0.85*, -1.19* resp.) . Three testers, AKR 492, AKR 492-1 and AKR 526 found promising for earliness like days to 50% flowering (-0.52, -0.74, -1.52** respectively) and days to maturity (-2.07**, -0.96**, -0.51 respectively). These lines and testers need to be extensively used in crossing programme for development of high yielding and early maturing kharif sorghum hybrids.
