豁眼鹅产蛋性能的遗传趋势研究

Study on Genetic Tendency of Huoyan Goose Egg Performance

用豁眼鹅产蛋系选育群3个世代,共37只公鹅的342只女儿产蛋量资料,采用最佳线性无偏预测法(Bestlinearunbiasedprediction,BLUP)分析产蛋系选育群的遗传趋势。结果表明:第一世代公鹅的最大遗传传递力为3.04个蛋,每二世代为4.14个,第三世代为2.19个;3个世代的效应值分别为78.68个、80.95个、82.38个,3个世代公鹅的平均育种值分别为-0.58、0.12、0.60,表现出逐代上升的遗传趋势。

To analyse the egg performance genetic tendency by BLUP(Best Linear Unbiased Prediction),and with three generational Huoyan goose egg performance population,the data get from 342 descendant female geese of 37 male geese.The result shows that the max transmitting ability of male geese is 3.04 in first generation. The second generation is 4.14. The third generation is 2.19. The effect values of three generations are 78.68, 80.95 and 82.38 respectively. The mean breeding value is -0.58,0.12 and 0.60 respectively. The mean breeding values are rising generation by generation.
