摘　　要：用太湖鹅、四川白鹅、豁眼鹅、皖西白鹅等4个我国主要白鹅品种,组成包括纯繁在内的15个组合,测定了60、70日龄仔鹅活重的杂种优势、纯繁效应、一般配合力、特殊配合力、正反交效应和母体效应。60日龄活重的一般配合力、母体效应、正反交效应达到显著水平(P<0.05),70日龄活重仅母体效应达到显著水平(P<0.05),60日龄活重的一般配合力,皖西白鹅为197.8克,四川白鹅为108.6克,豁眼鹅为311.1克,太湖鹅为-617.4克。70日龄活重的一般配合力,皖西白鹅为213.8克,四川白鹅为183.3克,豁眼鹅为21.9克,太湖鹅为-419.0克。60日龄活重这个性状四川白鹅(公)×豁眼鹅(母)组合具有最高的特殊配合力278.6克。以豁眼鹅为母本的3个杂交组合都具有正向的杂种优势。The 15 possible combinations including pure breeding and reciprocal crosses were made among four Chinese White Geese Breeds, i. e. Taihu, Sichuan, Huoyan and Wanxi to analyse the effects of heterosis, pure breeding, general and specific combining ability, sex linkage and maternal effects on 60-day and 70-day weight. General combining ability materal effects and effects of sex linkage were significant (P<0.05) at 60-day, but only maternal effects were significant at 70-day (P<^0.05). The general combining ability of the breeds were -617.4 grs, 183.3 grs, 21.9 grs and 213.8 grs for 70-day weight respectively. The specific combining ability of the cross combination between Schuan ( ) and Huoyan ( ) was highest (278.6 grs). Three cross combination using Huoyan goose as dam gave positive heterosis.
