摘　　要：测量了小荚蛏壳长、壳宽、壳高等壳性状和活体重、软体部重等经济性状.分析表明,小荚蛏各性状的相关系数均达到极显著水平(P<0.01).壳长与壳高、壳长与壳宽、壳高与壳宽、体重与软体部重均呈线性相关;壳长与体重、软体部重呈幂函数相关.多元回归分析建立的壳长(SL)、壳高(SH)和壳宽(SW)、估计活体重(WB)和软体部重(WF)的回归方程为:WB=-2.43+0.07SL+0.21SW+0.06SH,WF=-1.09+0.04SL+0.13SW-0.01SH.A total of 1001 individuals of Siliqua minima, were collected for the correlated response analysis of the quantitative characters. The shell length （SL）,shell height （SH）, shell width （SW）, live body weight （WB） and tissue weight （WF） were measured. The results revealed significant phenotype correlation between the parameters （P 〈 0.01）. Shell length was liner to shell width and shell height, Shell height was liner to shell width, Live body weight was liner to tissue weight. Shell height was power function to live body weight and tissue weight. The multiple regression equation obtained to estimate live body weight and tissue weight as： WB = -2.43 ＋ 0.07 SL ＋ 0.21 SW ＋ 0.06 SH,WF = -1.09 ＋ 0.04SL ＋ 0.13SW - 0.01SH.
