本研究测定我国1900份大豆栽培种(G.max)、半野生型(G.gracilis)、野生种(G.soja)的种皮过氧化物酶活性和根部荧光性基因表型频率。研究表明,这两个性状基因在我国 Soja 亚属三个种中的表型频率分布是不同的。野生种和半野生型具有较高频率的种皮过氧化物酶高活性和根部非荧光性基因,而栽培种则频率较低。各基因表型频率在栽培种中与种皮颜色、生育习性、结荚习性、百粒重等农艺性状有密切关系,其频率分布在我国地理纬度上表现出一定的规律性。结果还表明种皮过氧化物酶低活性基因和荧光性基因可能在大豆栽培驯化过程中得到积累。
In this study, the pericarp peroxidase activity and root fluorescence gene phenotypes of 1900 maize cultivars (G.max, G.gracilis, G.soja) in China were determined. Studies have shown that the phenotypic frequency distribution of these two trait genes in three subfamilies of Soja in China is different. Wild and semi-wild species have higher frequency of pericentrine peroxidase activity and root non-fluorescent genes, while cultivars are less frequent. The frequency of each phenotype was closely related to the color of seed coat, reproductive habits, pod habit and hundred-grain weight and other agronomic traits in cultivated species. The frequency distribution of these genes showed certain regularity in China’s geographical latitude. The results also show that the periclase peroxidase activity genes and fluorescent genes may be accumulated in soybean cultivation and domestication.
