高产高蛋白大豆皖豆28新品种选育及栽培技术

目的]介绍高蛋白大豆新品种皖豆28的选育及栽培技术。方法]皖豆28由安徽省农业科学院作物研究所于1996年以濮90-1为母本,宝92-1为父本进行有性杂交,经系谱法选择和海南加代选育而成。描述了该品种的产量表现及品种特征特性,并介绍了其栽培技术和试验示范情况。结果]皖豆28参加2005～2006年国家夏大豆品种区域试验,2年平均产量2 455.65 kg/hm2,比对照品种增产4.42%,并表现丰产、稳产、抗病、抗倒伏。该品种生育期107 d,单株有效荚数35.2个,百粒重22.1 g,籽粒蛋白质含量45.83%,脂肪含量19.94%,最佳种植密度为22.5万～27.0万株/hm2,在中高肥力田块易获高产。结论]皖豆28是高产、大粒、高蛋白夏大豆新品种,适宜在黄淮海南部地区作中熟夏大豆种植。

Study on Breeding and Cultivation Technology of a New High Protein Soybean Variety Wandou 28 with High yield

Objective] To introduce the breeding and cultivation technology of a new soybean variety Wandou 28 with high protein and high yield.Method] Wandou 28 was bred through first sexual hybridization with Pu 90-1 as the female parent and Bao 92-1 as the male parent,then selected with pedigree method and finally generation-adding in Hainan by Crop Institute of Anhui Academy of Agricultural Sciences in 1996.The yield preferment and variety characteristic of this variety were described and its main cultivation technique and trial demonstration were introduced.Result] In the area test of summer soybean variety in national regional test in 2005-2006,Wandou 28 got the mean yield of 2 455.65 kg/hm2 in 2 years,increasing by 4.42% compared with CK and showing the characteristics of high yield,stable yield,disease resistance and lodging resistance.The variety had the growing period of 107 d,the effective pods per plant of 35.2,100 grain weight of 22.1 g,protein content in grain was 45.83% and fat content was 19.94%.Its optimum planting density was 225 000-270 000 plants/hm2 and it was easy to get high yield in the field with middle-high fertility.Conclusion] Wandou 28 was a new summer soybean variety with high protein,big grain and high protein,which was the middle summer soybean suitably to be planted in the south area of Huang-Huai-Hai Plain.
