Abstract
|
|
|
|
Genetic polymorphisms was investigated at five single nucleotide polymorphisms(SNP) sites in four porcine genes(ADCYAP1R1, FABP3, MC4R, and MYL2) and analyzed their statistical association with growth traits in F2 reciprocal-crossbred population between Landrace and Jeju native black pig(JNP). All populations, JNP, Landrace and their F2 were polymorphic for all five SNP loci tested, however, the homozygote T/T of FABP3 g.-158T>C and the homozygote G/G of ADCYAP1R1 intron 2 337A>G were not found in JNP and Landrace, respectively. The genotypes of ADCYAP1R1 were significantly associated with body weights(BW) at 3 weeks and at 20 weeks(P<0.05), respectivley, those of FABP3 g.-135delT were associated with late average daily gain(LADG) (P<0.01), and those of FABP3 g.-158T>G were associated with body weights during late growth period such as, BW20 and LADG(P<0.01).
