Combining ability for grain yield and other agronomic characters in inbred lines of maize (Zea mays L.).

摘要

Information on combining ability is derived from data on grain yield, plant height, ear length, days to maturity and 1000-grain weight recorded in 6 inbred parental lines and their 15 F1 hybrids from a diallel mating, grown during 1994-95. Both general (GCA) and specific combining ability (SCA) effects were significant for all traits. Cross X year interaction was highly significant for plant height and days to maturity. GCA X year interaction was highly significant for grain yield, plant height anddays to maturity. SCA X year interaction was significant for days to maturity.
