| 摘 要： | 3年试验结果表明,在福州地区矮败小麦后代表现矮秆株不育。高秆株可育。矮秆性和不育性连锁遗传。从小麦拔节到抽穗期间,均可根据植株高度间接判别不育性,提高选择效率。矮败小麦株高表现连续分布,不育株内和可育株内均有一定差异,且不育株的高限和可育株的低限表现交叉,存在中间类型。在以株高为标记性状判别育性时,应选择明显高株和明显矮株。尤其在拔节期。更需选择极端类型才能准确,而对中间类型植株。仍需通过检查花药确定其育性。

| Abstract: | The rsults of three-years experiments showed that the shorter plants are sterile while the taller plants are fertile in the progeny of the Aibai wheat in Fuzhou District.The dwarfness and sterility present a linkage inheritance.It is possible to determine the fertility through the plant height from elongating stage to heading stage,and to increase the efficiency of selection.The plant height presents a successive distribution and the height difference appears within the sterile and fertile plants in the Aibai wheat.These two types of plants exist an intersection for the height.It is reliable to distinguish the fertility for extreme short and tall plants,especially in elongating stage when the plant height is used as marked character,but it is necessary to examine the anther of plants with moderate plant height so as to determine their fertility. |
