美国菜用大豆品种主要农艺性状比较

对引自美国东北部麻萨诸塞州的12个菜用大豆品种的主要农艺性状、结荚特性和产量性状进行系统观察,并与当地品种豫豆29号比较,结果表明:引进品种在新乡地区种植后比当地品种表现出早结荚、早鼓粒、早成熟等性状,可以在新乡地区种植.引进品种M-1、M-4、M-9、M-20、M-24的生育期为89～106 d,比对照品种短11～2...

Compare of the Agronomic Traits among Vegetable Soybeans Introduced from America

The major agronomic traits of 12 varieties of vegetable soybeans introduced from the north-eastern of the U.S.A.Massachusetts were observed and compared with a local species.The results showed that the date of pod setting,seed filling and seed maturing of the main introduced varieties were earlier than that of the local variety.The introduced varieties could be planted in Xinxiang.The whole growth period of M-1,M-4,M-9,M-20 and M-24 were 89-106d and were 11-28d shorter than CK.The pods with 2-3 seeds of M-4,M-9 and M-24 were 58.8-92 and were 3.8-37 more than CK.The seed number per plant of M-1,M-4,M-9 and M-24 was 127.8-198 and was 9.8-80 more than CK.The grain yield per plant of M-1,M-4,M-9,M-20 and M-24 was 28.4-54.6g and was 0.6-26.8g more than CK.Further studies on varieties of M-1,M-4,M-9,M-20 and M-24 should be carried out because of their good representation on the characters of growth period,yield,agronomic and economic traits.
