摘　　要：本文论述了塞北兔几个繁殖性状简化选择指数的制订，其塞北兔简化选择指数的公式如下：Ｉ＝４．０５４６Ｐ１＋０．０１９ＩＰ２＋０．０４３９Ｐ３公式中，Ｉ为简化选择指数，Ｐ_１、Ｐ_２、Ｐ_３分别为窝产仔数、泌乳力、断奶个体重，４．０５４６、０．０１９１、０．０４３９分别为三个繁殖性状的系数值。通过使用算图的方法，可大大简化计算指数的程序，且详细说明了算图的制作方法。This article deals wih the determination of simplified selection index of reproductivecharacter in Saibei rabbits.The index formula to be solved is as follows :I=4.0546P1+0.019IP2+0.0439P3 where,I means the index to be calculated. P1,P2,P3 mean the phenotypic value of littersize born alive,wt. of litter at 21 days,rabbit wt. at weaning reparately.4.0546,0.0191,0.0439 mean coefficient value of reproductive character reparately. The procedure of calcula-tion can be greatly simplified by using the method of diagram. Detail of making a calculatingdiagram are presented.
