摘要: 试验鉴定获得了猪MMP20基因第3内含子中的2个突变位点g.14334bpC>G和g.14369bpC>T,采用PCR产物直接测序法在大白猪群体中进行基因分型,并对母猪性状进行关联分析,结果发现这两个突变完全连锁,所组成的单倍型显著影响产仔数、产活仔数、21日龄活仔数、出生窝重和出生个体重性状(P<0.05)。GG/CC基因型个体产仔数最低,其次是GC/CT基因型个体,而CC/TT基因型个体产仔数最高。

关键词: 猪, 繁殖性状, MMP20基因, 突变, 关联分析

Abstract: In the present study two mutations (g.14334bpC>G and g.14369bpC>T) at intron 3 in porcine MMP20 gene were identified by Sanger sequencing. These two mutations were completely linked, and the association results showed that they significantly affected the reproduction traits (TNB, TNA, NAd21, BW and LW) in Large White pigs (P<0.05). GG/CC genotype sows had the lowest litter size, followed by GC/CT genotype sows, while CC/TT genotype sows had the highest litter size.

Key words: pig, reproduction traits, MMP20 gene, mutation, association analysis
