Comparative Analysis of Heterosis of Two-way and Three-way Cross Modes Mutton
摘要
Abstract
To investigate the best cross modes of mutton in farming pastoral zone in Jilin province,the Small Tail Han sheep was selected as female parent while the Suffolk sheep and Dorper sheep were selected as male parent,four hybridization modes of Dorper×Han,Suffolk×Han,Dorper×Suffolk×Han,Suffolk×Dorper×Han were used to analyse the body weight,body size index and heterosis rate.The result showed that four hybridization modes showed significant heterosis,and the heterosis of two-way cross mode was better than tree-way cross mode.These results indicated that genetic genes of Suffolk sheep and Dorper sheep,which regulated body weight and bust,could be stably inherited to future generations.Moreover,the hybridization effect of Dorper sheep crossed with Small Tail Han sheep was better than Suffolk sheep crossed with Small Tail Han sheep.关键词
