摘要
利用25个微卫星标记,对以隐性白羽鸡和仙居鸡为亲本建立的资源群体F2500只鸡进行遗传检测,并测定各个体的鸡肉pH值、失水率、嫩度和肌间脂肪含量,采用方差分析法对标记与性状进行相关分析。结果表明:各位点平均等位基因数为5,平均杂合度为0.701 2,平均多态信息含量为0.646 8。嫩度间与pH值存在显著的正相关(P<0.05),与肌间脂肪存在极显著的正相关(P<0.01),与失水率之间存在显著负相关(P<0.05)。方差分析显示:ADL136对肌间脂肪含量的影响极显著(P<0.01);MCW0095和ADL166对嫩度影响显著(P<0.05);MCW264对pH值影响显著(P<0.05);MCW264、ADL211和MCW0223对失水率影响极显著(P<0.01);其他标记对性状的影响未达到显著水平。
Twenty five microsatellite markers, selected from poultry genome were used to study genetic diversity and four meat quality traits on F2 generation obtained from the mating of Reqessive White chicken with Xianju chicken. Effects of 6 loci on meat quality traits were analyzed with PROC GLM of SAS 9.0 statistical software. The results indicated that, the averages of allelic number,heterozygosity(H) and polymorphism information content (PIC) were 5,0. 701 2 and 0. 646 8, respectively. There were positive correlations between tenderness and pH values(P〈0.05) and high positive correlations between tenderness and IMF(P〈0.01). On the other hand, the correlation between tenderness and water-losing rate was negative and of high values(P〈0.01). The effect of ADL136 on IMF and MCW264,ADL211 and MCW0223 on water-losing rate were hightly significant (P〈0. 01) ,while the effect of MCW0095 and ADL166 on tenderness and MCW264 on pH values was also significant(P〈0.05). No other significant effects on the four meat quality traits were obtained.
