根腐病对我国的谷物农场为害甚大,在对病原体发展有利的条件下,根腐病可造成减产30％以上。 1971～1973年我们在接种环境下,对800份全苏作物栽培研究所的春小麦品种原始材料,进行了抗根腐病能力的鉴定。试验结果证明,在大量人工接种环境下,所有品种的感病都不轻,其中没有发现免疫的品种,但地理起源不同样本间发病程度是有差别的。苏联本国培育的品种中,感病程度最低的品种如下:萨拉多夫33,萨拉多夫38,阿尔泰33 Root rot is very harmful to cereal farms in China. Under favorable conditions for the development of pathogens, root rot can cause a decrease of more than 30%. From 1971 to 1973, we identified the resistance to root rot of 800 spring wheat cultivars from the All-Soybean Cultivation Institute in inoculation environment. The test results show that in a large number of artificial inoculation environment, all varieties of flu is not light, no immune species found, but the geographical origin of different samples of the degree of difference there is a difference. Among the cultivars cultivated in the Soviet Union, the varieties with the lowest susceptibility were: Saladoff 33, Saladoff 38, Altai 33
