对普通大麦(H.vulgare)5种类型103个基因型的幼胚进行了离体培养,并对幼胚诱导培养反应的遗传作了研究。结果表明,5种类型及基因型的幼胚经离体培养后均能诱导出愈伤组织,平均出愈率为88.4%;分比率为9.1％:得苗率为6.2％,有22％的基因型未能分化出再生株。不同大麦类型及基因型间在培养反应上有较大差异,分化率是影响培养效率的主要因素。大麦幼胚愈伤组织的诱导主要受核基因控制,且不受细胞质效应及母体效应的影响,控制高愈伤组织诱导率和产率的基因为隐性。 The immature embryos of five types and 103 genotypes of H. vulgare were cultured in vitro and the inheritance of immature embryo-induced culture was studied. The results showed that callus was induced in all five types and genotypes of immature embryos, with an average callus rate of 88.4% and a cut-off rate of 9.1%. The rate of seedling emergence was 6.2% and 22% Genotypes failed to differentiate into regenerative strains. Different types and genotypes of barley have great differences in the culture response, and the differentiation rate is the main factor affecting the culture efficiency. The induction of callus from barley immature embryos was mainly controlled by nuclear genes, and was not affected by the cytoplasmic effect and maternal effect. The genes controlling the induction rate and yield of high callus were recessive.
