本试验对从八倍体小偃麦与普通小麦杂交后代中选育的１２个小麦种质系的细胞学和主要性状特点进行了鉴定。结果表明，在１２个种质系中，有７个是在小麦中附加了一对堰麦草染色体的双体异附加系，５个为染色体数目与普通小麦相同的遗传重组体，它们具有抗病、优质、大穗、大粒、矮杆等优良特点，在小麦育种中具有重要利用价值。
In this study, the characteristics of the cytology and the main traits of 12 wheat germplasm lines selected from the cross of the eight-tuploid inbred line and common wheat were identified. The results showed that among the 12 germplasm lines, 7 were the extragenic lines of Drosophila melanogaster added with a pair of barley grass chromosomes, and 5 were the same genetic recombinants with the same number of chromosomes as that of common wheat. They had disease resistance , Good quality, big spike, big grain, dwarf bar and so on. It has important use value in wheat breeding.
