摘　　要：用轮回式部分双列杂交法对大麦花药离体培养力进行基因型差异及配合力分析。结果表明,花药愈伤组织诱导率的基因型差异显著;一般配合力(GCA)和特殊配合力(SCA)是相互独立的,且其方差均达极显著水平;遗传的差异既包含加性效应,也包括显性效应,但加性效应更为重要。因而针对花药愈伤组织诱导率而言,GCA效应是首要的,在GCA效应高的基础上,选配SCA效应高的组合,通过杂交可以选育出花药愈伤组织诱导率高的基因型。Genotype difference and combing ability of barley anther culture response were investigated by the way of circulated partial diallel crossing. The result suggested that the difference between genotypes in anther culture response was significant. On the anther culture response of genotypes, the general combing ability （ GCA ） and special combing ability （SCA） were independent each other, and both significantly different at 0.01 probability level. The genetic basis of anther culture response was controlled by dominance effect and additive effect, additive effect was more important than dominance effect. GCA would play critical roles in increasing the frequency of callus formation from anthers. It was indicated that parents with high SCA could be selected to use in the barley haploid breeding on the basis of the high GCA. Some parents with low callus induction rate could be improved by crossing breeding.
