| 摘 要： | 在德系黑白花奶牛中，对产奶量、乳蛋白量、乳脂量和奶中体细胞数四个数量性状进行基因定位，试验采用祖孙女设计法。试验动物为１６个父系半同胞家系共７５５头种公牛，试验共测定了８对染色体上的６４颗微卫星，父代公牛四个性状的育种值由孙代母牛估算得到。连锁分析采用回归间距定位法，临界Ｆ值由置换试验法得到。

| Abstract: | A total of 755 bulls belonging to 16 half sib families of German Holstein dairy cattle were genotyped for 64 microsatellite markers on 8 chromosomes. The data were used in an attempt to map quantitative trait loci applying regression as interval mapping approach. For association analysis with a granddaughter design, the estimated breeding values for 4 traits were used: milk yield, protein yield, fat yield and somatic cell count. The empirical values of significance thresholds were determined using a permutation test on the experimental data. |
