改变普通大豆生物学特性提高大豆产量的研究Ⅱ.中国扁茎大豆的生物学特性

CHANGING BIOLOGICALLY SPECIFIC CHARACTERISTIC OF COMMON SOYBEAN VARIETY TO INCREASE SEED YIELD OF SOYBEAN Ⅱ.BIOLOGICAL CHARACTERISTIC OF FASCIATED SOYBEAN OF CHINA

中国扁茎大豆是个不稳定的分离群体。与普通大豆品种相比较，节数较多，节间较短，叶数较多，叶柄较短。群体中也有与美国扁茎大豆相似的顶端花序类型，开花结荚密集，但植株中下部仍然有大量花序。中国扁茎大豆可能是吉林２０号大豆品种的突变体。

Fasciated soybean of China was a segregation population. It had more nods and leaves, shorter internodes and petioles than common soybean varieties, In the population of fasciated soybean of China, there was long top-inflorescence type that similar to fasciated soybean from America. On the top-inflorescence flowers and pods crowded together. There was a number of inflorescence at middle and lower plant parts in fasciated soybean of China, but there was not in fasciated soybean from America. The fasciated soybean of China probably was a mutent from Jilin No.20, a common soybean variety of North East.
