Seven lines were used as males in crosses with three lines having cytoplasmic-genetic male sterility to give 21 hybrids. When results for the hybrids from each maternal line were averaged over the seven paternal lines, those from Redlan were the first to reach midflowering and formation of the black layer, and gave the highest grain yields per day of any hybrid up to these stages. When results for the hybrids of each paternal line were averaged over the maternal lines, those involving the males 6, 9 and 10 were among the first to reach the above stages and yields. For individual hybrids, differences in both maturation time and especially grain yield by the time of black layer formation (GYBL) contributed to differences in daily grain yield. Further data support the view that Redlan and the male lines 6, 9 and 10 are promising parents for grain yield, but line 6, 9 and 10 had some undesirable quality and agronomic characters
