摘要
根据青海八眉猪 (本 )、长白猪 (长 )、杜洛克 (杜 )、大约克夏 (大 )及长×本、杜×本、大×本杂交组合的繁殖性状记录 ,研究了三种杂交组合繁殖性状的杂种优势率及其遗传方式。结果表明 :长×本、杜×本组合各繁殖性能的杂种优势较好 ,尤以长×本组合的产仔性能优势率较高 ,杜×本组合的生长性能表现较好 ,大×本组合繁殖性状的杂种优势率较低。
The heterosis rate and inheritance way of reproduction performance Qihghai Bamei swine with three kinds of cross combination were studied the reproductive performance record of Qinghai Bamei swine(Native),Landrace swine (Landrace),Duroc swine(Duroc),Large Yorkshire(Yorkshire)and Landrace×Native,Duroc×Native,Yorkshire×Native.The results showed that the heterosis of reproductive performance of Landrace×Native and Duroc×Native combination were better,espcially the birth performance of Landrace×Native was higher,the growth performance of Duroc×Native combination was better.The heterosis of reproductive performance of Large Yorkshire×Native combination was lower.Inheritance way of reproductive performance of three kinds of cross combination was intermediate type.
