对３１６份新育成小麦品种（系）进行了成株期分小种鉴定，结果表明：１９９７年新育成的小麦品种（系）大部分对条中２９号小种表现免疫—高抗，占总数的７４．２％，但对Ｈｙｂｒｉｄ４６Ⅲ和水源１１类群大部分表现感染。对５个生理小种均表现免疫或近免疫的品种有１８份，它们均为簇毛麦后代。由于新小种类型的出现，致使我省大部分新育成小麦品种表现感染 The results showed that most of the newly cultivated wheat cultivars (lines) in 1997 were immune to the race 29, which was highly resistant to the total number of lines Of 74.2%, but most of hybrid46Ⅲ and water source 11 groups showed infection. There were 18 varieties that showed immunity or near immunization to all 5 physiological races, all of them were offspring of Hamster. As a result of the emergence of new races, most of the newly bred wheat varieties in our province became infected
