超早熟大豆品系筛选研究

目的]对引种选育的24个超早熟大豆进行品种(系)比较试验,筛选出适合北疆麦收后复播的优质、高产、超早熟大豆新品种。方法]采用随机区组试验对参试品种主要农艺性状、产量性状及品质性状进行分析。结果]田间试验初步表明,HH-25早熟性最好,生育期为74 d,生育期短于79 d的品系有6个;产量达3 000 kg/hm2以上的品系有9个,HH-50的产量最高,为4 305 kg/hm2;高蛋白质的品系有4个,DN-41的含量最高,为42.5%;高油品系有3个,伊大豆1号的含量最高,为21.8%;蛋脂高的品系有5个,ND-4的含量最高,为60.4%。结论]大部分品系适宜麦后复播;部分品系具有高产、优质特性,有望成为北疆麦后复播后备新品种。

Field Trial of Ultra-early Maturing Soybean Varieties

Objective] Field trial was conducted to test performance of 24 earlier-maturing soybean varieties newly introduced and selected cropping after winter wheat in North Xinjiang.Method] The agronomic character,yield and quality traits of these varieties were analyzed with randomized block experiment.Result] The results showed that HH-25 characterized with the shortest growth period(74 d),and there were 6 varieties with growth period less than 79 d.Seed yields of 9 varieties were higher than 3 000 kg/hm2,and HH-50 has the highest yield(4 305 kg/hm2).There were 4 varieties ranked into higher protein one,and DN-41 with the highest protein content(42.5%).There were 3 varieties ranked into higher oil one,the highest is Yidadou 1(21.8%).The total protein fat contents of 5 varieties were higher than the others,and ND-4 has the highest protein fat content(60.4%).Conclusion] Most varieties tested were suitable for cropping after wheat,and particularly those varieties with high yield and high-quality may be play key roles in cropping after wheat in North Xinjiang.
