优质大豆在黄泛区的适应性研究

目的]筛选适宜黄泛区种植的大豆新品种。方法]以豫豆22(CK1)、周豆12(CK2)为对照,研究了13个大豆品种的田间表现与产量性状。结果]徐豆9号的生育期最短,为107 d,06B3、06B8、06B9、郑98120最长,为122 d。泛豆5号、06B3、06B8、郑98120最为抗倒。06B3株高最高,徐豆9号最低;泛豆9号的结荚高度最高,为37.7 cm,徐豆9号最低,为19.0 cm;节数以06B3最多,为22.1节,徐豆9号最少,为15.0节;分枝数以泛豆9号最多,06B9最少;株荚数以泛豆3号最多,06B9最少;株秕荚数以泛豆9号最多,郑98120最少。13个品种产量变化幅度在2 847~3 565.5 kg/hm2,06B8较CK1、CK2增产显著,泛豆5号较CK1增产显著。结论]06B8和泛豆5号可以推广种植。

The Study on Adaptability of Soybean with High Quality in Huangfanqu Area

Objective] The study was to screen out the new variety of soybean optimum to be planted in Huangfanqu area.Method] With Yudou 22 and zhoudou 12 as CK1 and CK2,the field performance and yield characters of 13 soybean varieties were studied.Result] The growth period of Xudou 9 was shortest(107 d),and that of 06B3,06B8,06B9 and Zheng 98120 was longest(122 d),the lodging resistance of Fandou 5,06B3,06B8 and Zheng 98120 was best.The plant height of 06B3 was highest and that of Xudou 9 was lowest.The pod-setting height of Fandou 9 was highest(37.7 cm) and that of Xudou 9 was lowest(19.0 cm).The node number of 06B3 was most(22.1) and that of Xudou 9 was least(15.0).The branch number of Fandou 9 was most and that of 06B9 was least.Pod-setting number per plant of Fandou 3 was most and that of 06B9 was least.The abortive pods number per plant of Fandou 9 was most and that of Zheng 98120 was least.The yield of 13 varieties varied from 2 847 to 3 565.5 kg/hm2.The yield of 06B8 was increased significantly than that of CK1 and CK2 and that of Fandou 5 was increased significantly than that of CK1.Conclusion] 06B8 and Fandou 5 could be generalized to be planted.
