| 摘 要： | 选用胫色、肤色均为深乌的四川山地乌骨鸡和黄肤、黄胫的岭南黄鸡作为参试品种,通过品种的纯繁和正反杂交,进行四川山地乌骨鸡肤色、胫色遗传规律的研究。结果表明:岭南黄鸡的肤色、胫色基因为纯合基因,四川山地乌骨鸡虽经四代纯繁选育,肤色、胫色基因仍未完全纯合,尚需进一步加强选育。在含有四川山地乌骨鸡血缘的组合(WW、WH和HW),初生雏鸡肤色、胫色尚未完全稳定,有随日龄发生转变的现象,说明控制肤色、胫色黑色素沉积的基因具有表达的时效性;用四川山地乌骨鸡(♂)与岭南黄鸡(♀)杂交,F1代10周龄时深乌个体几乎全为母鸡,而1日龄雏鸡依肤色或胫色尚不能进行雌雄鉴别;本实验结果也提示雏鸡体内的真皮黑色素含量似乎与雏鸡的死亡率有关。 |
| 关 键 词： | 乌骨鸡 肤色 胫色 遗传 |

Observation on the Inheritance of Skin Color,Shank Color in Sichuan Mountain Dark-bone Chickens (SMDC) |
|
| Abstract: | In order to make clear the inheritance of skin color, shank color in SMDC chickens, a cross between SMDC and Lingnan yellow meat chicken (LYMC) was conducted. The results indicate that the skin color and shank color of day old chicks are incompletely stable in the intercrossing groups, and they change with age, which indicates the expression of genes that controls the deposition of melanin changes with the age of chickens. In the population which are produced by intercrossing between SMDC (♂) and LYMC (♀), almost all darkly pigmented chicks are female at age of 10 weeks, but the sex of day old chicks can not be determined by skin color or shank color. The research also shows that the content of dermal melanin in the chicken seems to have certain relation with the mortality rate. |
