摘要
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。
The wheat line YW243 was developed by cross between diseaseresistant lines and anther culture.Its resistance was tested by many different races of yellow rust in the field and green house.The result indicated that the line had high resistance at seedling stage and adult stage.It was able to resistant to CY29,CY30,CY31,SU-11 and CY32 in China.Test crossing with susceptible wheat cultivatar Jing 771 was also conducted for this line.The result showed that YW243 was resistant to yellow rust and had a pair dominance gene which was different from known genes.Consequently,YW243 is possibly a wheat line with a new yellow rust resistance gene.
