摘要:

制片蚌珍珠层颜色是决定培育珍珠颜色的主要因素,珍珠层颜色性状已成为珍珠贝遗传改良的重要目标性状,但珍珠层颜色度量难度较大,严重降低了选育效率。本文选用12月龄红色、蓝色、金色和白色选育系三角帆蚌(Hyriopsis cumingii)幼蚌为试验材料,利用色差仪获得上述4个三角帆蚌选育系珍珠层颜色与外壳色的颜色参数L、a 和b值,并对各颜色参数进行相关性分析、主成分分析和回归分析,探索珍珠层颜色与外壳色之间的相关性。结果表明:4个三角帆蚌选育系珍珠层颜色与外壳色皆显著相关(P<0.05),红色和蓝色选育系珍珠层颜色与外壳色相关性相对更强。红色和蓝色选育系珍珠层颜色的L、a 和b值均分别与外壳色中至少1个颜色参数存在显著相关(P<0.05),其中红色选育系中珍珠层颜色的a值与外壳色的b值相关性最强(P<0.01),相关系数r为-0.557;蓝色选育系中珍珠层颜色与外壳色的L值相关性最强(P<0.01),相关系数r为0.533;金色选育系中外壳色的L值与珍珠层颜色的a和b值均显著相关(P<0.05),相关系数r分别为0.331和0.335;白色选育系中仅a值在珍珠层颜色与外壳色存在极显著相关(P<0.01),相关系数为0.286。本研究揭示了不同颜色选育系的三角帆蚌幼蚌珍珠层颜色与外壳色具有相关性,对指导三角帆蚌珍珠层颜色早期选育具有重要意义。

Abstract:

The nacre color is the main factor that determines the color of the cultivated pearls.The nacre color trait has become an important target trait of the genetic improvement of the pearl oyster,but the measurement of the nacre color is difficult,which seriously limits the efficiency of pearl mussel breeding.Using 1-year-old red,blue,golden and white strains of juvenile H.cumingii as experimental materials,the color parameters L,a and b values were obtained by the X-Rite ColorEye XTH spectrophotometer,while correlation analysis,principal components analysis,and regression analysis were performed on each color parameter to explore the correlation between nacre color and shell color.The results showed that the nacre color and the shell color of the four H.cumingii strains were significantly correlated,and the correlation between the nacre color and the shell color of the red and blue strains was relatively stronger.The L,a and b values of nacre color in red and blue strains were all significantly correlated with at least one color parameter in shell color.Among them,the a value of nacre color in red strains had the strongest correlation with the b value of shell color,with the correlation coefficient as -0.557 (P<0.01).The L value correlation between the nacre color and the shell color was the strongest in the blue strain,and the correlation coefficient was 0.533 (P<0.01).The L value of the shell color in the golden strain was significantly correlated with the a and b values of the nacre color (P<0.05),and the correlation coefficients were 0.331 and 0.335,respectively.In the white strain,only the a value had a very significant correlation between the nacre color and the shell color (P<0.01),and the correlation coefficient was 0.286.This study reveals that the nacre color is correlated with the shell color in these four H.cumingii strains of juvenile mussels,which is of great significance for guiding the early selection of nacre color of H.cumingii.
