摘  要:
为了寻找控制重要经济性状的基因座位 ,我们在国内较早开始组建资源家系。利用 3头大白猪和 7头梅山猪作父母本 ,产生F1 。F1 随机交配产生F2 ,147头F2 个体记录了生长、胴体及肉质性状。对各性状进行统计分析 ,结果表明 ,各性状变异程度大、变异范围广 ,性状间有不同程度的相关 ,从一个侧面预示着QTL的存在 ;同时 ,这些性状的统计分析 ,为定位QTL时协变量的选择提供了参考价值。

摘  要:
One three\|generation resource families of Large White×Meishan were established at Huazhong Agriculture University for gene mapping and quantitative trait loci(QTL)identification.147 F\-2 offspring were slaughtered in tow years for which a total of 30 traits to growth,carcass and meat quality were measured.The simple statistics and correlations of these traits showed a large range of variation and correlation.This could give a reference for localization of QTTL and selection of covariance factors.
