高产优质大豆新品种评价筛选研究

目的]为了适时更新宁夏大豆品种资源,筛选高产优质大豆品种,促进大豆发展。方法]以12个春大豆新品种为材料,主要对农艺性状、生物学性状进行品种的再评价并初步筛选主导品种。结果]2009年,产量位居前5位的大豆品种依次为承豆6号、晋豆42、晋豆19、K丰70-1和邯豆3号,产量分别为3 826.80、3 726.90、3 593.55、3 420.50、3 366.90 kg/hm^2;品种间没有显著差异。2010年,产量位居前5位的大豆品种依次为邯豆3号、承豆6号、晋遗42、晋豆19和K丰70-1,产量分别为4 942.50、4 646.90、4 311.30、4 231.35、3 660.15 kg/hm^2;除晋遗42与晋豆19品种间没有显著差异外,其他品种间差异达极显著水平。结论]邯豆3号、晋遗42、晋豆19和K丰70-1,各生物学性状及产量表现较优,可进一步大面积推广示范。

Evaluation and Screening of New Soybean Varieties with High Yield and Good Quality

Objective] To timely update soybean varieties in Ningxia,and screen the varieties with high yield and good quality for soybean development.Method] The agronomic traits and biological characteristics of 12 new spring soybean cultivars were re-evaluated and screened.Result] The top five high-yield soybean varieties in 2009 were Chengdou 6,Jindou 42,Jindou 19,K Feng 70-1 and Handou 3 with the yield of 3 826.80,3 726.90,3 593.55,3 420.50 and 3 366.90 kg/hm2 respectively.No significant significance was seen among varieties.The top five high-yield soybean varieties in 2010 were Handou 3,Chengdou 6,Jinyi 42,Jindou 19 and K Feng 70-1 with the yield of 4 942.50,4 646.90,4 311.30,4 231.35 and 3 660.15 kg/hm2 respectively,apart from Jinyi 42 and Jindou 19,the difference among other varieties was extremely significant.Conclusion] Handou 3,Jinyi 42,Jindou 19 and K feng 70-1 had good biological traits,therefore could be planted on large areas.
