摘要: 以中系长毛兔为母本,西德长毛兔为父本,进行级进杂交试验,两批F1代母兔的年累计平均产毛量分别为401.85克、486.97克,比我省原来中系毛兔年产毛量180克左右,分别提高了1.23倍和1.70倍,杂种优势率分别为19.64%和20.01%。F1代母兔在70日龄、100日龄、180日龄和成年时,体重增长的杂种优势率分别为32.57%、27.58%,11.70%和0.62%,随日龄增长而减弱。

Abstract: The grading cross-experiment was carried out with the China Angora Rabbit as the female parent and the German Angora Rabbit as the male parent. The result proves that:the average amount of the mulative fur production of two batches of the female rabbits of F1 generation is respectively 401.85g and 486.97g, which has repectively increased by 123% and 170% compared with the annual fur output of about 180g of the former China Angora Rabbits in Sichuan province. The frequency of the hybrid vigour is respectively 19.638% and 20.01%, and the frequency of the heterosis of the gain of the body weight of the female rabbits of F1 generation at the age of 70 days,of 100 days,of 180 days and in the adult period is respectively 32.57%, 27.58%, 11.70% and 0.62%, and also the frequency gradually weakens as the age increases.
