The association of endogenous viral (ev) genes with quantitative traits in 2 genetically distinct sets of White Leghorn strains were investigated. Strain S had been selected for susceptibility to Marek's disease (MD) whereas strain K had been selected for resistance to MD and high egg production and egg weight. 2. In all, 8 ev genes were typed. Ev10, ev19 and 'newB' occurred exclusively in strain S, 'newA' occurred only in strain K, and ev1, ev3, ev6 and ev8 occurred in both strains. 3. Whereas ev6 and ev8 were associated with reduction in egg production rate in strain S, in strain K, the presence of ev3 was associated with increased group specific antigen. 4. The genetic background of the chicken strain may play a role in the way certain ev genes affect traits. 5. It was thought that the position of ev genes on the chromosome may be important and their association with traits of economic importance make them potential genetic markers for uncovering quantitative trait loci.

研究了内源性病毒（ev）基因与两组遗传背景不同的白来航鸡品系数量性状之间的关联。品系S因对马立克氏病（MD）易感而被选育，而品系K因对MD具有抗性、产蛋量高和蛋重高而被选育。2. 总共对8个ev基因进行了分型。Ev10、ev19和“newB”仅出现在品系S中，“newA”仅出现在品系K中，ev1、ev3、ev6和ev8在两个品系中均有出现。3. 在品系S中，ev6和ev8与产蛋率降低有关，而在品系K中，ev3的存在与群体特异性抗原增加有关。4. 鸡品系的遗传背景可能在某些ev基因影响性状的方式中起作用。5. 人们认为，ev基因在染色体上的位置可能很重要，并且它们与经济重要性状的关联使其成为揭示数量性状基因座的潜在遗传标记。
