| 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. |
