为了选育更适合于湖南省栽培条件下种植的春大豆高产优质品种,用丰产性较好、中熟偏早的春大豆品种湘春豆12号与早熟、优质春大豆品种湘春豆17号杂交,经多代选择、产量鉴定、品比试验及省内多点试验,于2006年育成了比普通早熟品种早熟6 d以上,且丰产稳产性好,适合湖南及南方类似地区种植,蛋白质、脂肪双高的春大豆新品种,2007年2月已通过湖南省农作物品种审定委员会审定,定名为湘春豆25号.

In order to breed out high yielding and high quality soybean variety with better adaptability to cultivating condition of Hunan province, high yielding and early medium mature spring soybean variety Xiangchundou 12 and high quality and early mature spring soybean variety Xiangchundoul7 were crossed. Through continuous selection, yield appraisal, varietal comparison, and multi-spot production experiment in Hunan province, the variety Xiangchundou 25 were bred out and released in 2006. Xiangchundou25 is a variety with higher protein and higher fat content, its growth duration was over 6 days shorther than that of ordinary early maturing varieties, and its productivity was higher and stable. It is suitable for planting in Hunan province and other similar areas of south China. The high yielding cultivation technology for Xiangchundou25 has been studied as well.
