摘要/Abstract

摘要： 冬小麦(综抗矮6号×泰山1号)F_1代花培H_1代纯系经幼穗离体培养建立的13—7管无性系获得一株R_0代种子,后代变异类型多、频率高,其R_2、R_3代株高、抽穗期都呈一个正态分布、连续性变异,调查的几个性状在R_3代稳定率已达84.85—100％。已从稳定品系中选择出一批不同株高和高蛋白材料,其中4个品系比对照冀麦6号增产17.2—35.8

Abstract: An H_1 pure line obtained by anther culture of the F_1 of a winter wheat cross,Zongkangai No. 6 /Taishan No. 1, was used in immature inflorescence culture andthe seed of the only successful R_0 plant was harvested. Studies on the progenies ofthis R_0 plant showed that in vitro culture could lead to

Key words: Winter wheat, Anther cultured pure line, Immature inflorescence culture, Somaclonal variation
