The testing of haploproduction ability of soft winter wheat different hybrids in anther culture in vitro
Aim. Study the the efficiency of androgenesis in vitro in anther culture of different genotyps winter wheat. Methods. Obtaining of soft winter wheat double haploid lines by anther culture in vitro. The statistical methods. Results The ability to androgenesis in an in vitro anthers culture of 30 soft winter wheat genotypes was tested. The differences in the frequency of сallus induction and the ability to regenerate plants in the process of androgenesiss in vitro of winter soft wheat were detected. The range of variation haploproduction activiti (from % of implanted anthers) was broad. The sign of "the formation of сallus" was in limited from 0 to 13.2 % and on the sign of "regeneration of green plants" – from 0 to 1.8 %. The 126 green plants-regenerants were received. Conclusions. Genotype-specific of microspores morphogenetic reactions of soft winter wheat in the process of androgenesis in vitro were revealed. It is advisable to use the anthers from the F2 hybrid population plant as a donor material to create an effective technology for producing double haploids of soft winter wheat was shown.
