The magnitude of general combining ability (GCA) (additive) was higher than specific combining ability (SCA) (non-additive) mean squares for leaf angle (LANG), ears/plant (EPP), rows/ear (RPE), 100-kernels weight (100 KW), kernels/plant (KPP) and barren stalks (BS) under WW and WS, days to Original Research Article Al-Naggar et al. Maximum GYPP heterobeltiosis reached 736.0% by the cross L28 x Sd7 under WS. The largest average heterobeltiosis (236.58%) was shown under WS by GYPP. Data combined across seasons revealed that the inbreds L53, L20 and Sk5 and the crosses L20 × L53, L53 x Sk5 and L53 × Sd7 under WW and WS had the highest grain yield/plant (GYPP) and its components. Six inbreds and their diallel F 1 's were evaluated in 20 seasons in two experiments, one under well watering (WW) and one under water stress (WS) at flowering. The main objective of the present study was to assess performance, useful heterosis and combining ability among maize inbreds under optimum and drought conditions. Selecting superior parents for hybrid combinations and studying the nature of genetic variation are prerequisites for starting a successful breeding program. ![]()
