大豆北9939的选育及栽培技术研究

The Cultivation and the Process of Selective Breeding of Bei 9939

北9939是新疆农科院粮作所采用联合育种模式，于2002年从黑龙江省农垦总局北安农业科学科研所引进，经过异地鉴定，选择培育的早熟高产高油大豆新品种，籽粒蛋白质含量37．0％（干基），脂肪含量22．8％（干基），且蛋白质含量受环境影响较小，脂肪含量与蛋白质和脂肪总量受环境影响较大。2004～2005年参加新疆大豆品种（早熟组）区域试验，平均产量3400．05kg／hm^2，较对照阿豆1号增产8．68％，居参试品种第一位。2005年参加新疆大豆品种（早熟组）生产试验，平均产量2962．05kg／hm^2，比对照阿豆1号增产2．67％，居参试品种第二位。该品种适宜新疆北部冷凉大豆产区春播。

A new, early maturity, high yield and high oil soybean variety Bei 9939 was breeded by Grain Crops Institute, Xinjiang Academy of Agricultural Sciences, which was introduced from Beian Institute of Agricultural Sciences , Heilongjiang General Bureau of Agricultural Reclamation in 2002 through appraising in different place with combined breeding pattern .Protein and fat contents of seed in the variety were 37.0% （DM） and 22.8% （DM）, the former was less affected by environment, the latter and total contents of protein and fat was. Institute of Xinjiang soybean variety（ early maturity groups） regional trials were conducted in 2004 to 2005, its average yield was 3 400.05 kg/hm^2 and increased by 8.68% more than contrast Adou No. 1,which got the first in all experiment varieties yield. Xinjiang soybean variety by （early maturity groups） production trials were conducted in 2005, its average yield reached 2 962.05 kg/hm^2 and increased by 2.67% more than contrast Adou No. 1,which came to the second in all varieties yield.The variety was suitable for sowing in spring in north of Xinjiang.
