摘要
选择 2 5 6份我国各大豆栽培区代表性地方品种为供试材料 ,以国际通用的美国 0 0 0～X熟期组的 48份标准品种为对照 ,在南京进行分期播种及光照处理试验 ,制订出与国际相衔接的我国大豆生育期生态类型划分标准 ,将我国大豆划分为 0 0 0～IX熟期组 ;明确我国东北三省春豆归属 0 0 0～Ⅳ熟期组 ,并分析东北三省春豆熟期组地理分布概势。
To link the Chinese maturity groups system with the US system,forty eight varieties of 13Gs from the US and 256 land races from China were tested.The soybeans from China were classified into 000、00、0、Ⅰ、Ⅱ、Ⅸ.It was shown that the spring sowing soybeans from Northeast Sub region were grouped into 000、00、Ⅰ、Ⅱ、Ⅲ、Ⅳ.In addition,the geographical distribution of maturity groups of spring sowing soybeans from Northeast Sub region was also presented in this paper.
