研究了六倍体小麦（2n=6x=42）两个重要分类性状的遗传规律。证明了安提古鲁小麦（Triticum antiquorum Heer ex Udacz）球形粒的单基因控制。通过单体遗传分析，将控制该种球形粒的隐性基因定位于染色体3D上，并表明其与印度特有种T.球球藻霸王antiquorum和T.控制紧凑型穗的球球藻显性基因与相应的T. compactum宿主基因，命名为C2。讨论了六倍体小麦的发生和分类问题。
The inheritance of two taxonomically important characters was studied in hexaploid wheat species (2n=6x=42). The monogenic control of spherical grain was demonstrated for Triticum antiquorum Heer ex Udacz. The recessive gene controlling spherical grain in this species was localized to chromosome 3D by monosomic genetic analysis and was shown to be allelic to the s gene determining the same character in the endemic Indian species T. sphaerococcum Perciv. The T. antiquorum and T. sphaerococcum dominant genes controlling compact ears proved to be nonallelic to the corresponding T. compactum Host gene and were designated as C2. Problems of phylogeny and classification of hexaploid wheats are discussed.
