1985—1986年,选用我省冬麦、春麦的生产品种、后备品种、高代材料及亲本材料的144个品种(系),进行了成株期条锈菌新小种的致病性研究。条中26、27、28号新小种是1984年12月在北京召开的“全国条锈菌生理小种鉴定协作组”会议上定名的。条中26号原名“19—2”致病类型,1977年在我省就有出现,到1984年才上升为第二位,1985年居第三位,已成为小麦生产上的优势小种之一;条中27号原名“82—1”致病类型,1982年在我省首次出现,到1983年猛升为第二位,近两年有所下降;条中28号原名
In 1985-1986, 144 varieties (lines) of production, reserve, high-generation and parental materials of winter wheat and spring wheat in our province were selected to study the pathogenicity of the new races of stripe rust. The new breeds 26, 27 and 28 were named at the meeting of “National Stripe Rust Species Identification and Identification Team” held in Beijing in December 1984. Article 26, formerly known as “19-2” pathogenic type, appeared in our province in 1977, only rose to second place in 1984, ranking third in 1985 and became the dominant race in wheat production One; Article 27 formerly known as “82-1” pathogenic type, first appeared in our province in 1982, soared to second place in 1983, the decline in the past two years; Article 28, formerly known as
