小麦的抗锈育种是防治锈病经济而有效的方法,寻找抗锈基因,摸清抗锈性遗传规律,对有目的地选育抗锈良种,创造多基因品种,合理安排抗性基因的地理分布具有重要意义.关于小麦抗叶锈遗传的研究,国内尚缺资料.我们为了给育种部门提供科学依据,于1978和1979年分别配制了若干组合,以研究小麦品种抗叶锈性的遗传规律,1980和1981年对其第二代抗性分离取得了结果.一、材料和方法1.试验材料 1978年配制了7个抗病与感病的杂交组合,包括高加索×矮丰4号、百泉40×F_18-71、阿芙乐尔×四川764、郑州764×阿芙乐尔、郑引4号×安选5号、郑引4号×许丰一号、弗朗塔×郑州
Anti-rust breeding of wheat is a economical and effective way to prevent rust, looking for anti-rust genes, finding out the genetic law of anti-rust, selecting rust-resistant varieties for purpose, creating multi-gene varieties and rationally arranging the geographical distribution of resistant genes Is of great significance.For wheat leaf rust genetic research, the domestic lack of information.We in order to provide scientific basis for the breeding department, in 1978 and 1979 were formulated a number of combinations to study the genetic law of leaf rust resistance in wheat, Results of its second-generation resistance segregation were obtained in 1980 and 1981. I. Materials and Methods 1. Experimental Materials Seven resistance and susceptible crosses were made in 1978, including Caucasus × Aifeng 4, Baiquan 40 × F_18-71, Fufur × Sichuan 764, Zhengzhou 764 × Fuleer, Zheng cited 4 × × 5 election, Zheng cited × Xu Feng on the 1st, Frita × Zhengzhou
