摘要
采用人工授精方法,进行了家蚕和蓖麻蚕的种内和种间杂交试验,结果提示:1)在家蚕和蓖麻蚕的种内不同品种间杂交,人工授精的成功率较高,杂交后代的遗传表现也与采用自然交配的相同;2)在种间杂交的情况下,人工授精的成功率很低,而且其杂交后代的染色体数目和基本特征与母本相同或相似,但也有颇多变化,其遗传学意义尚待阐明。
By artificial insemination, the intra-and inter-specific cross of domesticated silkworm and eri silkworm were studied. The results indicated that: 1)In the intraspecific hybridization (between different varieties).the rate of success is higher, and the hereditary characters are the same as those of natural mating. 2)In the interspecific hybridization,the rate of success is much higher, furthermore, the number of chromosomes and many other basic characteristics of the hybrids are the same as or similar to those of the female parent. But, there are a lot of changes in them at the same time. Its genetic sense is to be clarified.
