适宜陕西关中地区夏大豆新品种选育研究

Evaluation of New Soybean Varieties Suitable for Summer Planting in Guanzhong Area of Shaanxi Province

为了筛选适宜陕西省关中地区夏季种植的大豆品种,以期提高该产区大豆的产量水平,对陕西省夏季播种的大豆11个品种(系)进行产量和农艺性状比较分析。结果表明:在参试的品种(系)中,‘V94-3971’的产量最高为243.2kg/667m2,比对照‘秦豆8号’增产39.6%,其次是‘21P369’,为239.8kg/667m2,较对照增产37.7%;其余增产的是‘XN21(20)-8’‘黄矮丰’和‘SFG04626’,分别较对照增产37.5%、15.9%和12.7%。4个品种(系)包括‘21P369’‘黄矮丰’‘SFG04626’和‘XN21(20)-8’,由于生育期适中,丰产性、抗病性、抗倒性、籽粒商品性等性状综合表现好,比较适宜陕西关中地区种植和推广。

New summer soybean varieties（lines）suitable to be planted in central Shaanxi were tested in terms of yield and other agronomic traits in order to increase the yield of soybean in central Shaanxi.Of all the varieties（lines）tested,‘V94-3971＇and‘21P369＇presented the first and second highest yields of 243.2kg/667m^2 and 239.8kg/667m^2,which increased by 39.6% and 37.7% compared with that of ‘Qindu 8＇as the control,respectively. ‘SFG04626＇‘Huangaifeng＇and‘XN21（20）-8＇showed yield increases within 12.7%-37.5% compared with ‘Qindu 8＇.Favorable appropriate growth,higher yields,resistances to diseases and lodging,commercial appearances of four summer soybean varieties（lines）,‘Huangaifeng＇‘21P369＇‘SFG04626＇and ‘XN21（20）-8＇,determined that they were varieties suitable to be adopted and promoted in Central Shaanxi.
