摘要
根据淮南猪原种场１９８５～１９９０年育种资料，系统研究了淮南猪繁殖性状的表型参数、遗传参数以及繁殖性状与生长发育性状间的遗传参数。淮南猪繁殖性状的在型参数在国内地方品种猪中居较高水平，遗传力估计值大多较低。性状间相关研究表明：在评定母猪繁殖力时应将断奶窝重和产仔数作为两项主要指标来考虑。
On the base of breeding test data gained by Huainan Swine farm in l985～1990,mean population,heritability,phenotypic correlation,genetic correlation and eviron-ment correlation to the reproductive characters of Huainan Swine are estimated.The phono-typic parameter of the reproductive characters of Huainan Swine is in the rather high level a-mong the swine breeds at home,heritability is in rather low level.The correlation amongdifferent characters are shown when evaluating dam swine reproductive characters,we mustconsider two main indexes of weaning weight of litter and the number of piglets which wereborn alive.
