吉林白鹅肉用品系的选育

Selection of the Meat Line of Jilin White Goose

吉林白鹅肉用品系是以溆浦白鹅为父本、吉林本地鹅为母本连续进行2代级进杂交,选择700只优秀 个体组成选育核心群,又经过5个世代自繁选育而成。其体形外貌、体尺、体重趋于一致,主要生产性能遗传 性稳定,成龄公鹅体重(7.20±0.17)kg,母鹅重(6.20±0.12)kg,70日龄杂交商品代体重比吉林本地鹅提高 0.97 kg,产肉性能提高极显著(P<0.01)。

2 generations' hybridization in succession with white goose of Xupu as male parent and Jilin local goose as female parent was conducted. 700 outstanding individuals were chosen to compose the nucleus breeding population, and after 5 generations' self-population breeding, Jilin white goose was obtained. Its physical appearance is unanimous, and its body measurement and body weight become balanced. The heredity of its main production performance is steady, adult goose weight is: male goose (7.20± 0.17)kg, female goose (6.20 ± 0.12)kg, and the body weight of the 70-day hybridized commodity generation is 0.97 kg greater than that of Jilin local goose. The improvement of meat production performance is significant (P<0.01).
