黄淮海春夏豆区大豆熟期组归属及地理分布概貌

Classification and Geographical Distribution of the Maturity Groups of Huang-Huai-Hai Soybean Cultivating Region in China

选择256份我国各大豆栽培区代表性地方品种,以国际通用的美国000～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000～Ⅸ熟期组;明确我国黄淮海大豆区春豆归属Ⅰ～Ⅲ组,夏豆归属Ⅱ～Ⅵ组,分析了黄淮海大豆区春夏豆品种熟期组地理分布概貌.

land races presented local characteristics of soybean cultivating region in China were sowed by instalment and tested with light in Nanjing,which contrasted with 48 standard species in US MG 000～Ⅸ.The classification standard of soybean ecological type in breeding period was made.The soybeans in China were classified into 000～Ⅸ MG.It was shown that the spring sowing soybeans in Huang Huai Hai soybean cultivating region were grouped into Ⅰ、Ⅱ、Ⅲ,and that summer sowing soybeans were grouped into Ⅱ、Ⅲ～Ⅸ.The geographical distribution of maturity groups of spring or summer sowing soybeans in Huanghuaihai soybean cultivating region was also presented in this paper.
