摘要
测定了利木赞×娟姗牛杂交一代3头公牛所有回交后代的背最长肌和半腱肌的剪切力、pH值及煮 制损失3个表型性状,与已构建的遗传连锁图谱和基因型值相结合,利用QTL Express软件的“Half-Sib QTL Analysis Servlet”进行QTL分析。共发现6个可能的QTL位点,其中背最长肌剪切力性状3个QTL(BTA2 45 cM,BTA29 54 cM)、半腱肌剪切力1个QTL(BTA2 12 cM)、半腱肌pH值1个QTL(BTA24 0 cM)、背最长肌 煮制损失1个QTL(BTA142 cM)。
Shear force, cook loss and PH value were assayed for Longissimus dorsi （LD） and Semi tendinosus（ST） of backcross progeny of 3 Limousin × Jersey F1crossbred sires, and the QTL analysis was done with the Half-Sib QTL Analysis Servlet of QTL Express by combined these phenotypes with the genetic linkage map and genotypes built previously, 6 considerable QTL were detected including 3 for shear force LD（BTA2 45 cM, BTA18 38 cM, BTA29 54 cM）, lfor shear force ST（BTA2 12 cM）, lfor PH value ST （BTA2 12 cM）, 1 for pH valus ST （BTA24 0cM）and 1 for cook loss LD（BTA14 2 cM）.
