1龄三角帆蚌壳形态性状对体质量的通径分析
|
摘要
为探究三角帆蚌Hyriopsis cumingii幼蚌各形态性状与体质量的相关关系,随机选取1龄三角帆蚌120只,测量其壳长(x_1)、壳高(x_2)、壳宽(x_3)、全高(x_4)和体质量(y)等5个数量性状参数,运用相关分析、通径分析对各性状间的相互关系进行了统计分析。结果表明:1龄三角帆蚌各性状间的表型相关均达到了极显著水平(P<0.01);壳长对三角帆蚌体质量的直接影响作用最大,为0.479,而壳高、壳宽与全高主要通过壳长间接影响体质量;壳长、壳高、壳宽、全高等形态性状对体质量的总决定系数为0.933,表明本研究中所列形态性状是影响体质量的重点性状,其他形状影响相对较小;壳长对体质量的综合决定系数最大,为0.641,是这些性状中理想的选育目标性状;运用逐步回归方法,建立了各形态性状对体质量的最优回归方程为y=-157.919+12.195x_1+5.266x_2+22.613x_3+4.920x_4。本研究结果可为三角帆蚌选择育种提供数据资料。
Five quantitative traits including shell length(x_1),shell height(x_2),shell width(x_3),total height(x_4),and body weight(y)were measured and statistically processed by correlation analysis,path analysis,and stepwise regression analysis in 120 individuals of one-year-old freshwater mussel Hyriopsis cumingii to evaluate the correlation between morphometrical characters and body weight.Results showed that there was significant Pearson correlation between morphological characters and body weight(P<0.01).Shell length had predominant direct effect(P_1=0.479)and determinacy on body weight,while shell width and shell height showed indirectly affects body weight via shell length.The total decision coefficient of all morphological characters was found to be 0.933,indicating that the body weight are primarily dependent of these morphometrics,less impact of other factors.The shell length has the maximal impact on body weight,with total decision coefficient of 0.641,being the ideal target trait for selective breeding among these traits.The optimal regression equation of morphological characters on body weight was expressed as y=-157.919+12.195x_1+5.266x_2+22.613x_3+4.920x_4by step wise regression analysis.The finding provides theoretical evidence and perfect measure targets for selective breeding of freshwater mussel.
