黄淮海地区大豆品系鉴定

目的]筛选适合黄淮海地区大面积推广种植的高产、优质、成熟期适宜的大豆新品种。方法]采用同一播期,间比排列设计,每5个或7个品种首尾设对照,对22个已筛选夏大豆品种再次进行比较试验。结果]中作04-19产量居第1位,平均为2815.5 kg/hm2,比相邻对照冀豆12增产17.50%；荷99-8产量居第2位,平均为2704.5 kg/hm2,比相邻对照冀豆12增产12.86%；中作06-06产量居第3位,平均为2667.0 kg/hm2,比相邻对照冀豆12增产11.30%,前3位和对照熟期相近,生育期日数均在107 d及以下。结论]中作04-19、荷99-8、中作06-06适宜在沧州地区作夏播种。

Identification of Soybean Cultivars in Huanghuaihai Region

Objective] The aim was to screen out high-yield, high-quality and appropriate mature period soybean new varieties which are suitable for large-area cultivation in Huanghuaihai Region. Method] Using the same sowing date, than arranged, setting control between ev-ery 5 or 7 varieties, 22 summer soybean varieties were compared again. Result] Top three yield was Zhongzuo 04 -19, He 99 -8 and Zhongzuo 06-06, average yield was 2 815. 5,2 704. 5 and 2 667. 0 kg/hm2 respectively, yield was increased 17. 50%,12. 86%, 11. 30%respectively compared with adjacent control Jidou 12. The mature period of top 3 varieties were close to that of control variety, days of growth period were all less than 107 d. Conclusion] Zhongzuo 04-19, He 99-8, Zhongzuo 06-06 are suitable for summer sowing in Cangzhou region.
