Correlation and path analysis of phenotypic traits on meat yield of Ruditapes philippinarum in different seasons
摘要
Abstract
In order to study the correlation between phenotypic traits and dry meat yield of Ruditapes philippinarum in different seasons,270 individuals in spring,141 individuals in summer,and 55 individuals in autumn were sampled in Xiangshan Bay,respectively.The shell length(X1),shell height(X2),shell width(X3),back edge length(X4),frond edge length(X5),live body mass(X6),soft part mass(X7),and shell mass(X8)were measured.The dry meat weight(X9)was then obtained by dehydrating the soft part mass.SL/SH(X10),SL/SW(X11),SH/SW(X12),FEL/BEL(X13)and dry meat yield were calculated.Correlation analysis,path analysis,determination coefficient analysis,and regression analysis were conducted to identify the main traits affecting the meat yield of the clams and to establish regression equations.The results showed that the coefficient of variation for the soft part mass of the autumn populations was the highest,while the coefficient of variation for morphological traits was relatively lower.In summer,the number of phenotypic traits significantly correlated with dry meat yield were the highest.Path analysis indicated that shell length,shell height,and shell width were important factors affecting dry meat yield.In particular,shell width had a significant positive impact on the meat yield of the R.philippinarum,especially in autumn and spring.In summer,the ratio of shell height to shell width had a significant negative impact on dry meat yield.The regression equation for the dry meat yield of the spring population is:Y=-9.765+0.888X1-1.470X6-0.379X4+0.609X3,R2=0.157.The regression equation for the dry meat yield of the summer population is:Y=5.89+0.884X2-5.473X12-0.413X5,R2=0.474.The regression equation for the dry meat yield of the autumn population is:Y=35.286-11.076X11,R2=0.161.These research findings provide theoretical reference for the selection of high meat yield strains in R.philippinarum.关键词
