苏联柴里恩地区锈病大发生时,所有春性普通小麦地方品种,均表现极不抗秆锈和叶锈,从而严重的影响了产量和品质。叶锈在乳熟期、秆锈在成熟期发生最严重,尤以晚熟品种和迟播小麦受害更大。普通小麦地方品种叶锈感染率达50—80％,甚至更高;秆锈感染率达67.9％。科学院院士沃维洛夫指出:利用种内和种间杂交是选育抗锈品种的基本途径。有关研究机关,根据高度抗锈和其它一系列优良性状,对从全世界征集来的春小麦品种进行了鉴定、
When the rust occurred in the Charyrian area of the Soviet Union, all the spring native common wheat cultivars showed very little resistance to stem rust and leaf rust, which seriously affected the yield and quality. Leaf rust in milky maturity, stem rust occurred in the most serious maturity, especially late-maturing varieties and late-sowing wheat victims. Common wheat varieties of leaf rust infection rate of 50-80%, or even higher; stalk rust infection rate of 67.9%. Wavilov, a member of the Academy of Sciences, points out that the use of intraspecific and interspecific hybridization is the basic way to breed anti-rust varieties. Relevant research institutions, based on a high degree of resistance to rust and a series of other fine traits, were appraised from all over the world for spring wheat varieties,
