| 英文摘要 | 研究了4月龄条石鲷形态特征的相关关系,采用通径分析方法计算了以体质量为依变量,其他性状为自变量的通径系数和决定系数。结果表明,体质量、全长、体长、头长、躯干长、尾柄长、眼后头长、体高和尾柄高9个性状之间的相关系数为0.065~0.949,大部分达到极显著水平(P<0.01);各性状对体质量的直接影响不同,体高对条石鲷的体质量的直接作用最大,通径系数为0.596,决定系数为0.3552。所测各性状对体质量的总决定系数为0.8808,表明所选性状是影响体质量的主要性状。如果该阶段对条石鲷进行性状选择育种,可根据体高、全长性状进行选择育种,对体质量进行间接选择育种,从而保证选择育种的效果。; The correlation of morphological characteristics of the 4-month-old stone bream(Oplegnathus fasciatus)was studied,and the body weight,path coefficient and determination coefficient were calculated via path analysis.The results showed that the Pearson correlations between every two metric traits were ranged from 0.065 to 0.949,with significance(P<0.01);the data showed that the effect of morphometric traits on body weight was different,the trait with the strongest direct effect on body weight showed effect on body depth,with path coefficient of 0.596,and determination coefficient of 0.3552.The total decision coefficient of various characters to body weight was 0.8808.The findings showed that the selected character was the main body quality properties;during the selection breeding of this phase,the body depth,total length should be considered for the indirect selective breeding of the body quality,to ensure the effect of selective breeding.; 福建省教育厅A类科技资助项目(JA12347) |
