国内外大豆品种在保定生态条件下生态反应

STUDIES ON PERFORMANCES OF CIVIL SOYBEANS AND EXOTIC SOYBEANS UNDER THE ENVIRONMENT OF BAODING

本文就国内外推广的４１个大豆品种在河北保定生态环境下的生态反应和性状表现进行了综合分析。结果表明，东北大豆品种由于日照的改变，使得品种生育期缩短、产量和品质性状改变；国内大豆品种与国外品种相比在分枝数和分枝英数、单株总英数、单株粒数方面存在差距。筛选出３个在本地区表现早熟优良的品种和两个菜用大豆品种。

The trait performances and ecology reaction of 41civil and exotic soybeans were studied under the environment of Baoding. The results showed that growing period shortened, yield and quality characters of Northeastern - Area varieties chang owing to the changes of daylight hours. Civil varieties in comparison with the exotic ones are fewer in their branches, pods per branch, pods per plant, grains per plant.
