摘要
研究选用草原红牛、草原红牛与利木赞牛杂交后代共计40头作为试验牛群体,以体尺、体重作为衡量其生长发育指标,利用SPSS软件分析了8个微卫星位点基因标记与体尺性状的关系。结果表明,IDVGA55等位基因C(203bp)对体高、十字部高和坐骨端高三个体尺性状有正效应;BM2113等位基因C(142bp)对腿围性状有正面影响;ETH225等位基因A(123bp)对腰角宽具有正面影响;BM1824等位基因A(171bp)对十字部高性状有正效应,等位基因C(179bp)对胸深性状有正效应;TGLA44等位基因E(221bp)对体重有正面影响。
In this study,40 individuals of Grassland Red Cattle(GLRC)and its improved hybrid by Limousine(LM)were chosen as test population,and the body measurements traits and body weight were used to evaluate their growth and development,and the relationship between the body measurements traits and body weight trait and 8 microsatellite genetic markers was analyzed by using SPSS.The results showed:for microsatellite loci IDVGA55,allele C(204bp)had a positive correlation with Body height,Height at hip cross(HHC)and Height at capitulum body measurement traits.For BM2113,allele C(142bp)had a positive correlation with gam girth.For ETH225,allele A(123bp)had a positive correlation with waisr corner width.For BM1824,allele A(171bp)had a positive correlation with Height at hip cross(HHC) and allele C(179bp)had a positive correlation with Chest depth.For TGLA44,allele E(221bp)had a positive correlation with body weight.
