| 摘 要： | 观察了７３１Ａ、六千辛Ａ、轮回４２２、７７３０２的开花习性，并对其相互杂交的结实率进行了调查。与六千辛Ａ相比，７３１Ａ开花持续天数较短，开颖角度较小，柱头外露率低，开闭时间略长。在相同授粉条件下，７３１Ａ与轮回４２２的结实率低于六千辛Ａ与７７３０２。

| Abstract: | The flowering characteristics of 731A, the CMS line of Siyou 422, Liuqianxin A, Lunhui 422, the R line of Siyou 422 and 77302 were observed. Compared with Liuqianxin A, 731A has a shorter period of flowering days, a smaller angle of glume opening and a longer glume opening time. Under the same pollinating conditions, the seed set of 731A/Lunhui 422 was lower than that of Liuqianxin A/77302. The methods of increasing the F 1 seed yield of Siyou 422 were also discussed. |
