摘要：
The objective of this study development one or more elite single cross hybrids. The experiments were conducted in spring and fall seasons, during 2012 and 2013 Ten inbred line of maize (BK164, BK147, BK129, BK128, BK127, BK121, BK115, BK110, BK110, BK105, BK104) were used to develop single crosses by Griffing first method. The parents, crosses and two cultivars of maize (Buhoth 106 and 5018) were evaluated using RCBD with three replicates at the farmer field at Al-Anbar Province. The results were revealed significant differences in all the studied traits and heterosis. The crosses BK164 X BK104, BK147 X BK115, BK128 X BK110 and reciprocal cross BK115 X BK164 produced highest grain yield (229.1, 245.8), (211.9, 229.7), (206.6, 210.7), (217.7, 238.9) gm.plant(-1) respectively. While, in spring season the reciprocal cross BK115 X BK129 produced the higher grain yield 207.9, 205.8, 202.9, 200.7 gm.plant(-1) respectively. The superior crosses could be use as elite crosses and conduct the agronomic experiments to evaluate, what's need.
