太行和吕梁山区大豆生态型间差异比较

选择山西省西部吕梁山和东部太行山区及二者过渡带平川盆地农家大豆资源50份进行了生态型间差异比较研究,结果表明:吕梁山旱地大豆生态型以高度抗旱类型为主;子粒椭圆和扁圆粒型居多数,小粒型为主;种皮黄色为主,保持一定比率种皮深色类型;开花迟,开花时期平均48.2 d,生育期149.0 d;紫花,无限结荚型;株高99.3 cm,分枝数5.8个,半匍匐型。太行山旱地大豆生态型以中高抗旱类型较多;子粒圆粒中大粒居多数;种皮青色或黄色;开花迟,开花时期平均25.9 d,生育期平均135.6 d;白花,无限结荚为主;株高71.0 cm,分枝数4.4个,半直立型。平川旱地大豆生态型以中大圆粒居多,种皮黄色,开花早,开花时期平均33.7 d,生育期128.9 d,白花,亚有限与无限结荚习性兼有,株高58.2 cm,分枝数2.7个,直立型。

A Comparison of Ecotype Differences between Soybean in Luliang and Taihang Mountain Areas

50 local soybean resources,from mountain areas in Luliang and Taihang where belong to the east and west parts in Shanxi respectively,and from plains in center Shanxi between Luliang and Taihang,were chozen to do comparison amony soybean ecotype.The result showed that in Luliang mountain area soybean ecotype are: drought resistance of high degree mostly;seed grain shape of long round and flat round mostly;and small granule dominate;seed capsule yellow also keeping certain ratio to dark color type;effloresce time lately,abloom length average 48.2 d,growth period about 149.0 d,purple flower,immensity growth type,plant height average 99.3 cm,branches average 5.8,growth prostrate.The Taihang mountain area soybean ecotype are:drought resistance of middle-high degree mostly,seed grain shape with round mostly,and seed tend to bigness,seed capsule yellow or green type,effloresce time lately,abloom length average 25.9 d,growth period about 135.6 d,white flower,immensity growth type,plant higt 71.0 cm,branches average 4.4,growth habit with erection in the middle.The plain soybean ecotype are: seed grain shape of round only,and seed tend to bigness,seed capsule yellow type,effloresce time early,abloom length average 33.7 d,growth period about 128.9 d,white flower,immensity or finity growth type,plant higt 58.2 cm,branches average 2.7,growth habit with erection.
