在同作物真菌和细菌性病害的斗争中,培育抗病品种是主要方向,如用抗病品种塔什干类型更换发病严重的108夫,提高了产量。但对真菌生理型——黄萎病原菌的专一抗性逐年消失。在全苏中部地区农业科学研究所的试验田里,同时散播两种黄萎病原菌生理型的毒素,浸染力最强的取名为生理型“B”,浸染力较差的取名为生理型“A”。对抵抗生理型“B”的品种现在还没
In the fight against fungal and bacterial diseases of crops, it is the main direction to cultivate disease-resistant varieties. For example, replacing the severely ill-tempered Tashkent with the resistant varieties increases the yield. However, the specific resistance to fungal-Verticillium wilt pathogens disappeared year by year. In the experimental field of the Academia Sinica Central Research Institute, two kinds of toxins of Verticillium dahliae were disseminated at the same time. The most digestible force was named physiological “B” and the poorer dipping ability was named as physiological “ A ”. The resistance to physiological “B” species is not yet
