中华绒螯蟹新品种"长江1号"是以体形特征标准、健康无病的长江水系原种中华绒螯蟹为基础群体,以生长速度为主要选育指标,经连续5代群体选育而成。该品种生长速度快,2龄成蟹生长速度提高16.70%;形态特征显著,背甲宽大于背甲长呈椭圆形,体型好;规格整齐,雌、雄体重变异系数均小于10%。
A new variety of Eriocheir sinensis named ＂Changjiang l＂by continuous five-generation mass se- lection was bred based on healthy and disease-free Yangtze River stock.
