合浦珠母贝4种壳色选育系主要性状的比较分析

为评估合浦珠母贝（Pinctada fucata）白壳、黑壳、红壳和金壳色选育系F6代的育种性能,对养殖达18个月龄4种壳色合浦珠母贝的形态、质量、闭壳肌拉力和抗才女虫寄生病等12个性状指标进行了方差分析和多重比较。结果显示,4种壳色选育系间壳高、绞合线长、壳宽、体质量、壳质量、软体部质量、闭壳肌质量、闭壳肌拉力、右壳感染率和贝壳感染率均存在显著差异（P〈0.05）。综合相关分析表明,白壳色选育系可作为壳高和低才女虫感染率同时选育的最优育种群体,金壳色选育系可作为壳宽、体质量和闭壳肌拉力复合选育的最优育种群体。该研究结果为开展合浦珠母贝多性状复合选择育种工作提供了科学根据。...

To evaluate the breeding performance of sixth generations of pearl oysters（ Pinctada fucata）（ white,black,red and gold shell color selective lines）,we analyzed 12 indices of morphological traits,weight,shell-closing strength and resistance to Polydora ciliata for an 18-month culture cycle by ANOVA. Significant difference was found in shell height, hinge length, shell width,body weight,shell weight,tissue weight,adductor weight,shell-closing strength,infestation ratio of right shell and infestation ratio of shell among four shell color selective lines（ P〈0. 05）. The average values of selective breeding traits indicate that white shell color line was the best line for growth of shell height and resistance to P. ciliate. Golden shel
