| 摘 要： | 调查了1366份水稻品种和品系,腹缺米的发生频率为5.63%,腹缺米频率与粒重的相关r=0.6195。1978、1979和1981年,用腹缺米和饱满米配制了17个组合,F1、F2和 BF1的分析发现,腹缺米受两对显性互补基因控制,环境条件只影响腹缺米的程度。这种障碍在早期世代进行连续选择即可消除。

| Abstract: | The occurance frequency of notched grain type in total 1,366 rice varieties and lines investigated has an average value of 5.63% and the correlation between notched type frequency and grain weight was positive with r=0.6195. In 1978, 1979 and 1981, 17 combinations were made among notched and normal grain varieties. F1, F2 and BF1, populations were analysed.It was found that notching was controlled by two pairs of complementary dommant genes in this study. Environmental conditions affected the degree of notching only. Such obstacles could be removed by successive selections at early generations. |
