| Abstract | ||
| The objective of the experiment was to diagnose a single hybrid or more produced from 10 inbreds. The experiment was conducted spring and fall of 2012 and 2013. Ten inbred lines of maize (BK164, BK147, BK129, BK128, BK127, BK121, BK115, BK110, BK110, BK105 and BK104) were used in this study. The inbreds were used in full diallel cross. Parents, crosses, reciprocals and the two cultivars of maize (Buhoth 106 and 5018) were evaluated using RCBD with three replicates. The results were showed difference among all the traits and years. The crosses BK164 X BK104 and reciprocal cross BK128 X BK110 were produced highest grain yield 229.1 and 245.8 gm.plant-1 and 217.7 and 238.9) gm.plant-1 in both fall seasons, respectively. While in spring the reciprocal cross BK115 X BK129 and diallel crosses, BK164XBK105 were produced higher grain yield. The results showed importance of cytoplasm inheritance in all the studied characters. This research need crop management studies. | ||
