四种紫胶虫雄性外生殖器观察及初步杂交试验

On the Male Acdeas of Four Species of Lac Insects and Preliminary Cross Breeding Test

紫胶虫遗传育种工作在我国几乎还是空白。印度人在紫胶虫的育种方面做过的工作,主要是在紫胶虫种内不同品系间进行杂交。紫胶虫种间杂交的研究,国内外尚未见报道。 杂交育种是解决我国紫胶质量的有效途径之一。紫胶虫的种间杂交首先必须弄清杂交亲本双方能否进行交配,即在交配上有无障碍,生殖器是否吻合。为解决这个问题,我们对四种不同种的紫胶虫的雄性外生殖器进行了观察、比较,探讨了四种紫胶虫相互杂交的可能性,并进行了初步的杂交验证。

This paper reports the cross breeding test of lac insects in China. The results have shown that these different species of lac insects (Kerria lacca, K. sindica, K. chinensis, K. fici) can be alternatively crossed without barrier. The crossing test has also shown that the crossing between K. sindica and K. lacca is amphimictic.
