| Abstract | ||
| An experiment was conducted at Gerdarasha Research station/ College of Agriculture during spring and fall season at 2010.The crosses were mode between five parent (S70, 3078, kr640, pio3751, 890) using half diallel method which `grated 10 F1 In Fall season R.C.B.D with three replication involved (5 parents + 10 F1). The G.C.A and S.C.A and some genetic parameters were estimate. The results showed that value of G.C.A was greater than S.C.A for the characters plant height, No. ears/plant, No. kernels/row and the yield. Heritability in narrow sense was high for days to 50% silking and tasseling, ear height, ear length .No. rows/ear and 100 kernel weight. Conform the improving these characters by selection. While the low narrow senses heritability for plant height. No. ears/plant, No. kernels /row and yield. Indicate that the improving of these characters may be made by hybridization. | ||
