[Effects of microsatellite DNA markers on meat quality traits in pig chromosome 13].
In this reseanch, 7 microsatellite DNA loci linked with PPAR gene were selected from the published genetic map of chromosome 13 in pig,and polymorphisms of these microsatellites in 100 samples from Sutai pigs (Duroc x Erhualian) populations were detected. Results revealed that the number of alleles were 6-9, heterozygosity 0.59 - 0.81, polymorphism information content 0.51 - 0.76. Effects of S0021, SW1937, SW482, S0222, S0293, S0281 and SWR2054 on meat quality traits were analyzed with PROC GLM of SAS. Results showed that the effects of S0021 on pH value and SW937 on water-holding capacity reached a significant level at P < 0.01 respectively. The effect of S0293 on tenderness and SW482 on BFT were also significant (P < 0.05). S0222, S0281 and SWR2054 had no significant effect on the 7 selected meat qualitytraits (P>0.05).
