    家蚕的抗氟性及其与数量性状的相关研究

    STUDY ON THE FLUORIDE-RESISTANCE OF BOMBYX MORI AND ITS RELATIONSHIP TO QUANTITATIVE CHARACTERS

    • 摘要: 测定家蚕幼虫抗氟中毒的抵抗能力,4龄>3龄>2龄。强抗原种杂变组成的杂种一代,抗性介于两亲之间,弱抗原种杂交组成的杂种一代,其抗性表现出超亲的遗传现象,不同浓度的氟素对品种间的生长发育影响有着显著的差异,说明了品种间的抗氟能力存在着差别;抗氟性与DNV抗性有着显著的相关性;与茧质性状表现为不显著的正相关,抗氟性与蚕血中Ca~(2+)、Mg~(2+)含量无明显的相关关系。

       

      Abstract: Investigation on the fluoride-resistance of silkworm,Bombyx mori,and estimation of the corelatlonship between the fluoride-resistance and the other economic characters had been conducted.These can provide the scientific basis for the breeding of anti-fluoride races.The resistance to the fluoride-poisoning is strengthened with the growth of silkworm larvae,that is,4th instar>3rd instar>2nd instar.The resistant ability of F1 hybrids of the strong fluoride-resistance crossing groups was in between that of the parents'.For the Fl of the weak fluoride-resistance crossing groups,their resistance expressed was higher than their parents'.The resistance of different varieties was significantly different due to the various concentrations of fluoride.The andi-fluoride and the anti-DNV characters wen in significant positive corelation.But there were no such corelation to the cocoon quality,and the content of Ca and Mg ions in the larvae blood.
