【摘要】 用五龙鹅产蛋系选育群三个世代,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(Best linear unbiased prediction,BLUP法)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;三个世代的效应值分别为63.68个、65.95个、67.38个,三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。更多还原

【Abstract】 To analyse the egg performance genetic tendency by BLUP (Best Linear Unbiased Prediction),and with three generational Wulong 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 63. 68, 65. 95 and 67. 38 respectively. The mean breeding value is -0. 58,0. 12 and 0. 60 respectively. The mean breeding values are rising generation by generation.更多还原
