摘要: 通过对白丝羽乌骨鸡的复冠父系和单冠母系进行家系选育5个世代,在早期体重、孵化性能、开产性能及产蛋量方面得到了明显进展,而且可见单冠在这些性状上的正向效应。尤其是产蛋性能上的选育进展非常明显,开产后头4个月产蛋量增加了1倍左右,300日龄产蛋量达到110个左右,500日龄产蛋量超过220个。

Abstract: Through 5 generations' strain breeding of rose or pea comb paternal strain and Single comb maternal strain in white Silkies, distinct progress was obtained in early body weight, incubation traits, maturity and egg production. The positive effects of single comb on these traits are also distinctly expressed. The egg production of first 4 months in the fifth generation is two times as in the first generation. The age of 300 days egg production of two strains reaches 110 eggs or so, and the age of 500 days egg production is more than 220 eggs.

Key words: WHITE SILKIES, STRAIN BREEDING, SINGLE COMB, ROSE OR PEA COMB
