摘要
利用 1 B、4D蓝单体小麦和 73( 36) 9- 1单体系统 ,经 7年 7代连续培育 ,获得冬性自交结实和具有不同遗传背景 1 B、4D缺体小麦 9个 ,73( 36) 9- 1缺体小麦 1 6个 ,并利用选育的缺体小麦 ,应用“缺体回交法”选育出了抗逆性强的 4D( 4 R)、4D( 4 E)和7A( 7F)三类普通小麦异代换系和
Nine Varieties of 1B and 4D nullisomic wheat and sixtee varieties 73(36)9\|1 nullisomic wheat with different heredity backgroungs and self\|fruit characters were obtained after seven years' sequential breeding and selection by using 1B and 4D blue\|seed wheat and 73(36)9\|1 monosomic system as parent materials.Three types of alien substitutions ,4D(4R)、4D(4E) and 7A(7F),with good resistance and seven new valuable nullisome varieties were selected by nullisomic backcross using the nullisomic varieties that had been selected before.
