摘要
对家蚕的杂交后代采用不同的选择方法，可获得不同的选择效果，累代添氟饲养直接选择法＞蛾区半分法的间接选择法＞常规饲养选择法。经７个世代的选择，添氟系和选种系的抗氟性均高于对照系，茧质性状则以对照系略高，但差别较小。
Different selection effects were observed by different selection methods in con- tinuous selection of the hybrid offsprings of 7532×Guang408 and 837×Su5 forseven generations in three years. That is, direct selection with increasedfluoride added to feed of each generation > indirect selection with divided rearing lots > conventional selection. Measured by LC50 , the fluoride-resistance of theoffsprings of 7532×Guang408 and 837×Su5 in the increased fluoride groupincreased by 35.4% and 25.6% respectively as compared to the control group. However, the cocoon quality was slightly better in the control group.
