【摘要】 用单元内同胞相关法对法系獭兔 3个世代的繁殖性状和生长发育性状进行了遗传力估计，并对 6月龄的体重体尺进行了相关分析。结果表明：产仔数 (0． 15)和初生窝重 (0． 20)属中等遗传力性状； 21日龄个体重 (0． 42)、 32日龄断奶个体重 (0． 38)及成活数 (0． 42)皆属高遗传性状； 3月龄体重 (0． 37)及体尺 (0． 28～ 0． 37)属较高遗传力性状，而 6月龄的相应性状遗传力值 (0． 47～ 0． 63)明显地高于 3月龄。 3月龄体重与 6月龄体重、 6月龄体尺间皆有很高的遗传相关 (0． 81～ 0． 96)和表型相关 (0． 46～ 0． 79)。更多还原

【Abstract】 Genetic parameters of reproductive and growth traits in 3 generations of French Strain Rex rabbit were estimated by the method of half－ sib correlation within male－ line unit． Correlation analysis on 6－ month weight(wt．)and body measurements of Rex rabbits were studied at the same time． The results indicated that the heritability of litter size at birth,birth wt． of litter， 21－ day wt． ,weaning wt． and living litter size at 32days are 0． 15， 0． 20， 0． 42， 0． 38 and 0． 42 respectively,the first two be medium and the rest to be high． 3－ month wt．(0． 37)and body measurements(0． 28～ 0． 37)belong to higher heritability,while the values(0． 47～ 0． 63)at 6 months are higher than that of 3－ month distinctively． As to genetic and phenotypic correlation， 3－ month wt． with 6－ month wt． and between body measurements at the age of 6 monthes， are all high values．更多还原
