大豆短叶柄弱枕性状光温反应及遗传的初步研究

Primary Studies on the Responses of Soybean with Characters of Short Petiole and Weak Pillow to Temperature and Day Length and its Inheritance

大豆短叶柄突变体ＮＪ９０Ｌ－ １ＳＰ 短叶弱枕性状的表达受光温反应影响较大，当月平均温度达到２４ ．５ ℃，光照长度为１４ ～１５ｈ／ｄ 时，ＮＪ９０Ｌ－ １ＳＰ 植株叶柄表现为短叶柄（ ≤１０ ．０ｃｍ） 弱枕性状（ 叶枕凹状） 。该突变体的短叶柄与弱枕性状之间为完全连锁或一因多效。

The soybean short petiole mutant NJ90L-1SP has a weak pillow character. The character is influenced by temperature and day length. The petiole of NJ90L-1SP is short (≤10.0 cm) with weak pillow only when monthly average temperature reaches to 24.5℃and day length is 14～15h. The short petiole is completely linked with weak pillow and the character is controlled by one or two pairs of allogenes.
