在抗锈育种过程中观察分析了不同材料对条锈病抗性的遗传行为,也为此单独设计了一些试验。结果表明:(1)不同抗锈材料对条锈病抗性的遗传行为有显性、隐性、简单、复杂之别。所谓抗锈性遗传传递能力的“强”、“弱”是抗锈性的显、隐性遗传和抗锈基因数目多少的共同结果。(2)供试材料大多呈不完全显性或隐性遗传,呈完全显、隐性遗传的极少。感病亲本和锈菌生理小种都对显、隐性的表现有影响。(3)抗锈基因分析工作虽没有完成,但也看到不同材料抗锈性遗传的简单或复杂程度是有差异的,尤皮号、奥克曼、维尔、水原11等对条锈病抗性的遗传比较简单。并提出利用回交后代检验亲本抗锈性遗传简单或复杂的方法。(4)对抗锈性遗传行为不同的亲本材料的利用价值,进行抗锈基因分析的方法,以及今后抗锈性遗传研究的前景也进行了讨论。
During the process of anti-rust breeding, the genetic behaviors of different materials on the resistance to stripe rust were observed and analyzed, and some experiments were designed for this purpose. The results showed that: (1) The genetic behavior of resistance to stripe rust in different anti-rust materials was dominant, recessive, simple and complex. The so-called anti-rust genetic transmission ability “strong”, “weak” is rust-proof significant, recessive genetic and anti-rust gene number of common results. (2) Most of the materials tested were not completely dominant or recessive, showing complete and recessive genetic rarely. Sick parents and rusty races all have significant effects on the phenotype and recessive behavior. (3) Anti-rust gene analysis Although the work is not completed, it is also found that there is a difference in the genetic simpleness or complexity of rust-resistance of different materials. The resistance to stripe rust in Youkai, Oukman, Weir, Suwon 11 and so on The genetic is relatively simple. And proposed the use of backcross progenies to test the parents of rust resistance genetically simple or complex method. (4) The use value of parental materials with different genetic activities of rust resistance, the methods of anti-rust gene analysis and the prospects of genetic research on rust resistance in the future are also discussed.
