6.荷包红鲤抗寒品系 亲本来源:黑龙江野鲤×荷包红鲤 选育单位:黑龙江水产研究所 采用黑龙江野鲤和荷包红鲤杂交,将黑龙江野鲤的抗寒因子转移给杂种,再通过F1自交,从分离的F2中获得一个携带抗寒因子、红色体色、全鳞的荷包红鲤。再通过二代强化选育,培育成一个体型似荷包红鲤的抗寒品系,抗寒能力提高到95％以上。生长速度比亲本快10％。荷包红鲤的抗寒品系自育成后,已推广到黑龙江、吉林、内蒙和新疆等地,收到一定效益。荷包红鲤抗寒品系具有较强的抗寒能力,生长速度和含肉率都比亲本
6. Purse red carp cold-resistant strains of parents Source: Heilongjiang wild carp × purse red carp Breeding unit: Heilongjiang Institute of Fisheries Heilongjiang wild carp and red purse hybrids, the Heilongjiang wild carp cold-resistant factor transferred to the hybrid, and then by F1 selfing, from isolated F2 to get a cold-carrying factor, red body color, full-scale purse red carp. Through the second generation of enhanced breeding, breeding into a body-like purse red carp cold-resistant strains, cold-resistant capacity increased to 95%. Grow faster than the parent 10%. Cold-blooded red carp after self-fertility, has been extended to Heilongjiang, Jilin, Inner Mongolia and Xinjiang, received some benefits. Purse red carp cold hardiness has strong cold resistance, growth rate and meat content than the parent
