Abstract:

Genotype difference and combing ability of barley anther culture response was 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.
