提高品种对枯萎病的抵抗力,是获得细绒棉高额而稳定产量的重要因素之一。棉花育种站在两年内,在两种环境下,即不感染枯萎病菌的土壤上,和专门感染枯萎病菌的土壤上,进行了苏联细绒棉的选育工作。然而,这一方法的结果,只能在年中或年末才能划断出育种材料的抗病程度。这得付出很多的时间和劳动,抗病型要到秋季才表现出来,如果要杂交,还得等待下一年。为了加速育成新品种,我们在全苏棉作科学研究所中央选种站用染菌温床的方法,研究了育种材料对枯萎病的抗病力的鉴定,并获得了良好的效果。它能在棉花播种到田间去以前,鉴定出育种材料对枯萎病的抗病力。
Increasing the resistance of varieties to Fusarium wilt is one of the important factors for obtaining high and stable yield of fine cottons. The Cotton Breeding Station conducted the breeding of fine cottons in the Soviet Union within two years in two environments, soil that did not infect Fusarium oxysporum, and soil that was specially infected with Fusarium oxysporum. However, as a result of this method, the disease resistance of the breeding material can only be severed at the middle or the end of the year. This has to pay a lot of time and labor, disease-resistant type did not show up until autumn, if you want to cross, have to wait for the next year. In order to speed up the breeding of new varieties, we used the method of dyeing bacteria breeding beds in the central selection station of the Institute of Science and Technology of the whole Soviet Union to study the identification of the disease resistance of the breeding materials against the blight, and achieved good results. It was able to identify the resistance of breeding materials to Fusarium wilt before cotton was sown in the field.
