荷包红鲤抗寒品系是选用黑龙江野鲤与江西婺源县荷包红鲤杂交,然后通过杂种 F_1自交,获得荷包红鲤的个体自繁,经几代筛选育成适于北方地区养殖的抗寒品系。这个品系主要形态特征:体色为桔红色,体长/体高比为2.15倍,体长/头长比为2.8倍,尾柄长/尾柄高比为0.57倍,具有原种体色和体型。荷包红鲤抗寒品系虽然在体色、体型性状上与原种相同,但在其它性状上基因仍带有黑龙江野鲤种质表现出抗寒和生长快的特性。其生长速度快于原种5%～10%,成活率达95%,自然越冬成活率为90%,
Cold-resistant purse red carp is the selection of Heilongjiang wild carp and Wuyuan County, Jiangxi red purse hybrids, and then self-hybrid F1 hybrids, red purse to obtain the individual since the fan, after several generations of breeding bred suitable for breeding in the northern region of the cold-resistant strains . The main morphological characteristics of the line: body color is orange, body length / body ratio of 2.15 times, body length / head length ratio of 2.8 times, caudal peduncle length / caudal ratio of 0.57 times, with the original species color and body size . Although cold-resistant strains of red purse carp were the same as the original ones in body color and body shape, the genes of Heilongjiang wild carp still showed the characteristics of cold resistance and fast growth in other traits. Its growth rate is faster than the original species 5% to 10%, the survival rate of 95%, the natural survival rate of overwintering 90%
