摘要： 对300个冬小麦常用亲本和它们的部分F₁后代花药培养力的研究表明，愈伤组织诱导率和绿苗分化率都是可遗传性状。它们受不同的遗传基因控制，具有各自的遗传特性。杂种1代的愈伤组织诱导率具有明显的加性效应和杂种优势，而绿苗分化率则介于双亲之间。花培后代再进行花培的花药培养力明显高于一般常用亲本。花药培养力受环境影响很大，生长在正常大田环境下的植株其愈伤组织诱导率明显高于生长在温室条件下的植株。筛选出京花1号、NS2625、813①-21-2-3等几个花药培养力较好的材料，可在花培育种中作为桥梁品种应用。

Abstract: The research on anther culture ability for 300 conventional parents of winter wheat and their F1 progenies showed that the frequencies of callus induction and greenplantlet differentiation were controlled by different genes. The calli induced from F1 progenies demonstrated an obvious additive effect and hybrid vigor ,and the greenplantlet differentiation rate of the F1 progenies was between their parental pairs.Anther culture ability of the anther cultured progenies was found obviously higher than that of the conventional parents. The anther culture ability was severely affected by environmental conditions.The callus induction rate of the plants normally grown in the field was much higher than that of the plants grown in the greenhouse in winter. Some varieties with good anther culture ability, such as Jinghua No1, Ns2625 and 813 ① 21 2 3 had been selected, which could be used as bridge varieties in wheat breeding Via anther culture.
