“赣豆４号”（原代号赣８３－６０）系江西的中熟春大豆“六月白”与从福建引进夏大豆“融豆２１”杂交，经多年选育而成的大豆新品种。该品种具有高产、优质、抗逆性强、适应性广的特点，经省区试鉴定，适应全省各地区种植，属春大豆类型。中熟，全生育期９５ｄ，株高５０～６０ｃｍ，株型紧凑，茎秆粗壮，有限结荚习性，结荚高度１５ｃｍ左右，单株结荚２５～３０个，单株生产力９～１０ｇ。叶片大小中等，叶色深绿。花白色，荚果茸毛棕色，成熟后呈褐色，不易裂荚。每荚粒数２～３粒，籽粒椭圆，种皮黄色有光泽，脐褐色，百粒重１８～２０ｇ，粗蛋白质达４５．３％，脂肪含量为１８．６８％。１９９１～１９９４年参加江西省预试和区试平均产量达１９３８．６８ｋｇ／ｈｍ２，比ＣＫ（矮脚早）增产１１．１％，居第一位，１９９３～１９９５年生产示范平均产量１９７８．１ｋｇ／ｈｍ２。通过Ｎ、Ｐ、Ｋ及密度试验对该品种的综合研究、筛选出了三种高产高效最佳栽培模式。１９９６年通过江西省农作物品种审定委员会审定。
“Gan Dou 4” (formerly “Gan 83-60”) is a new soybean variety that has been bred for many years by crossbreeding “Jun Yue Bai”, a middle-aged spring soybean from Jiangxi province, with “Xiaodong 21”, a summer soybean introduced from Fujian. The varieties with high yield, high quality, strong resistance, wide adaptability characteristics, the provincial test identification, adapted to all regions of the province planting, is a spring soybean type. Medium maturity, the whole growth period of 95d, plant height of 50 ~ 60cm, plant compact, stalks stout, limited pod habit, pod height of about 15cm, plant pod 25 to 30, single plant productivity 9 ~ 10g. Medium leaf size, dark green leaf color. Flowers white, pod hairy brown, mature brown, not easy to crack pods. Each pod has 2 ~ 3 grains, the oval of the grain is yellow, the seed coat is yellow and shiny, the umbilicus is brown, the weight of the grain is 18-20g, the crude protein is 45.3% and the fat content is 18.68%. From 1991 to 1994, the average output of pre-test and regional test in Jiangxi province reached 1938.68kg / hm2, which was 11.1% higher than that of CK (bantet), ranking the first place. The average output of demonstration in 1993-1995 was 1978.1kg / Hm2. Through N, P, K and density tests of the variety of comprehensive research, screened three kinds of high yield and efficiency of the best cultivation patterns. In 1996 through the Jiangxi Provincial Crop Variety Approval Committee.
