Abstract: An albino group of plateau pika (Ochotona curzoniae) was bred in the latoratory of our institute．The hair-color heredity and biochemical canse of albino phenomenon of plateau pika were studied．The results mainly are as foliow ：
(1) The albino characteristics of the pika．white hair and red eyes,are controlled by recessive genes and can be inherited stcadily．
(2)The characteristics of wild-color pika,brown hair and black eyes，are controlled by dominant genes．
(3) The cause of albino phenomenon of platcau pika is due to the albino pika can not produce enough quantity of melanin．
(4) Genes which control albino characteristic of plateau pika are not distributed on the sexual chromosomes．
In this paper，the growth and development of albino pika are compared with those of wild-color plateau pika, There are no obvious differences in them ，but litter size of albino pika is less than wild-color pika.
