YW243是通过多种抗源复合杂交、花药培养选育的普通小麦新品系,经多年田间和室内条锈病生理小种接种鉴定表明,YW243在苗期和成株期均高抗国内现流行的条中29号、条中30号、条中31号、SU-11、条中32号等多种生理小种;与感病品种京771测交后代遗传分析证明该品系含有1对显性抗条锈病基因。
YW243 is a new common wheat line which is bred by multiple anti-source hybrids and anther culture. The inoculation identification of physiological races in field and indoor stripe rust showed that YW243 was highly resistant to the current prevailing strip in the seedling and adult stage In the No. 29, Article 30, Article 31, SU-11, Article 32 and other physiological races; and susceptible varieties Beijing 771 cross-test the genetic analysis proves that the line contains a pair of dominant resistance Rust disease gene.
