| 摘 要： | 用不完全双列杂交法研究了东农群体－１的两轮自交系的产量、穗长、穗粗、德行数、百粒重的一般配合力．结果显示出，第二轮自交系产量配合力较第一轮提高５％，穗长和穗行数分别提高４．４１％，３．５％，穗粗和百粒重提高不明显．

| Abstract: | The GCA on grain yield. ear length. ear diameter, number of ear row and weight/100 grain of inbred lines from two cycles of improved NEAU population-1 were studied by means of incomplete diallel crosses. The results showed that the yield combining ability of in bred lines from secound cycle was 5% higher than that of first cycle. The car length and num ber of ear row inereased 4.41% and 3.5% respectively.The car diameter and the weight/100 grain did not in crease significantly. |
