易门县中海拔区大豆品种比较试验

为筛选出适宜易门县种植的抗病、高产、稳产大豆品种，引进6个大豆新品种开展品种比较试验。结果表明：云黄1408-1、云黄1408-2、云黄1202-5田间表现生长势较强、抗病性好、综合性状优，产量均突破4 500 kg/hm²，分别比对照品种中品661增产38.39%、36.42%、34.98%，可在易门县中海拔大豆产区进一步示范种植；齐黄34田间表现早熟、株矮抗倒伏、籽粒大且均匀饱满，适宜作鲜食大豆；云黄1202-6和云黄1202-4-2田间表现植株高、百粒重较大，产量中等，可进一步试验。

Comparative experiment of soybean varieties in mid-altitude area of Yunnan

In order to solve the problem of insufficient raw material production of Soya bean industry in Yimen County of Yunnan Province,Six new soybean varieties were introduced to carry out comparative study on high yield, stable yield and disease resistance in middle altitude area of Yimen County,the aim of the study was to screen out disease-resistant,high-yield and stable-yielding soybean varieties suitable for local cultivation in Yimen County.The results showed that the yield of the six cultivars was increased by 10.488-38.392% than that of the control variety Zhongpin 661,Yunhuang 1408-1, Yunhuang 1408-2 and Yunhuang 1202-5 had strong growth potential, good disease resistance and excellent comprehensive traits in the field.Their yield ranked the first, second and third, they had strong growth potential, good disease resistance and excellent comprehensive traits in the field. Their yield ranked the first, second and third,increased 38.392%, 36.424% and 34.979% compared with that of Zhongpin 661. They showed high and stable yield in the field, suitable for net seed and high yield demonstration.Yunhuang 1408-2 and Yunhuang 1202-5 have compact plant types and can be used for soybean and corn strip compound planting. Qihuang 34 can be used as fresh food because of its early maturity in field, short plant, lodging resistance and large grain. Yunhuang 1202-6 and Yunhuang 1202-4-2 have large 100-grain weight and medium yield, which can be further tested.
