Adrina Grama等人最近报道,他们用7个野生二粒小麦的选株(具有抗条锈病菌Puccinia striiformis F. sp.tritici的且对温度敏感的微效基因)进行互交后,在所有组合的F_2代中都观察到它们的超亲分离对条锈病具有抗性趋势.由此可见,野生二粒小麦中出现的抗性确系加性基因的作用.在随机组合中
Recently, Adrina Grama et al. Reported that after reciprocal crosses with seven strains of wild durum wheat (microspresses with temperature resistance to Puccinia striiformis F. sp. Tritici) and in all combinations F_2 generations of their progeny were observed on the trend of resistance to stripe rust.Thus, the emergence of the wild wheat is indeed the role of additive resistance genes.In a random combination
