本文分析了中国各大豆栽培区大豆遗传资源的生育期表现,东北春大豆区的大豆品种多为早熟和极早熟种。黄淮夏大豆品种以中热种居多。长江流域夏大豆品种成熟期分布比较分散,晚熟和极晚熟种多于早熟和中熟种。秋大豆则以中熟种占多数,大豆是以不同生育期和播期类型适应各地条件的,不同生育期的大豆遗传资源极为丰富。
This article analyzes the growth of soybean genetic resources in each soybean cultivation area in China. Most of the soybean varieties in the spring soybean area of Northeast China are premature and very early-maturing. Huanghuai summer soybean varieties are mostly in the heat. The distribution of summer soybean varieties in the Yangtze River Basin was more dispersed during maturity, with late-maturing and late-late-maturing species more than those in early maturity and medium maturity. Autumn soybeans are the majority of mature varieties, soybeans are different types of growth and sowing season to adapt to various types of conditions, different growth stages of soybean genetic resources are extremely rich.
