摘要： 随着生活水平的提高,猪肉的肉质问题已引起消费者和生产者的重视。遗传
因素是改善肉质品质的关键。对猪的肉质性状进行数量性状位点(QTL)定位是当前国际畜禽遗传育种的一个热点。本文较全面地介绍了有关肉质基因定位的情况,包括基本明确的主效基因:氟烷基因和酸肉基因;肌内脂肪的统计分析、候选基因及基因扫描定位结果:以及肌纤维、嫩度、多汁性、失水率、pH值和肉色的定位。同时论讨了肉质检验和基因定位面临的问题。
Abstract:People tend to be interested in meat quality when the standand of living has been increased.Location of quantitative trait loci(QTL)affecting meat quality were performed in many countries.The objective of this review is to provide a detailed introduction of meat quality mapping in pig.It included halothane gene,acid meat gene,intramuscular fat,firmness,fruice,drop loss,pH value and meat color.It also discussed the problems of meat quality testing and QTL mapping.
