The processes of the study are:1.appling mordern principles and methods of animal breeding and fully using domestic and abroad excellent breed resources to build the ideal basic herd.2.recombinating good genes of the basic herd and by method of overlapping of generation of non-complete closed population to establish the coarse-wool rabbit lines with steady hereditary characters and good productivity.The performances of two lines and their offsprings are as follows:average adult weight 5 344.26g,annual wool yield 1 648.74g and coarse-wool rate 19.82%of paternal line,average adult weight 5 027.31g,annual wool yield 1 585.74g,coarse-wool rate 21.79%and litter size 8.72 of maternal line,average adult weight 5 574.26g,annual wool yield 1 734.32g,coarse-wool rate 22.64%and ratio of feed-wool 42.5∶1 of their offsprings.
