Abstract: FSH β subunit gene polymorphism and the relationships between FSH β subunit gene and little size traits of the first parity in the new Huai pig line group with 212 sows were analyzed in this paper. In the New Huai Pig Line sow group, A allele of FSH β subunit gene is the superior allele, and its gene frequency is 0.6085. To the litter size traits of the new Huai pig line sows, AA genotype of FSH β subunit gene is the beneficial genotype, and the sows of AA genotype produce 1.47 total number born(P<0.01) and 1.15 number born alive(P<0.05) more than the sows of BB genotype do in the first parity.
