摘要
Abstract
[ Objective ] The program aimed to determine the optimai hybrid iines and offspring by using ordinary method to caicuiate heterosis rate in different hybrid groups of Bashbay and wiid Argaii sheep. [ method Heterosis rate of body size and body weight of newborn and 4. 5 months iambs of backcross hybrids was anaiyzed. Result The resuits showed that heterosis rate of the newborn F2 backcross generations 4. 5 months and 12 months iamb weight was 9. 25% , 17. 74% and 13. 7% , which was 6. 25% , 7% and 9. 8% higher than F1 backcross generation heterosis. The differences were not significant (P > 0. 05). During the growth segments of backcross generations from birth to one years oid at 4. 5 months oid the weight heterosis rate was the highest. The significant difference was 17. 74% P < 0. 01. [ Conclusion 4. 5 months F2 generation backcross iambs have high profitabiiity of the best siaughter and high heterosis rate of body size and body weight. It was the good source for deveioping new iines of Bashibai iean sheep.关键词
