摘    要:在“珍珠贝育种规划(Pearl Oyster Breeding scheme,POBs)”中,马氏珠母贝的两个地理种群——印度养殖种群和三亚野生种群正在作为两个基础群(Basic population)建立专门化品系,通过杂交获得杂种优势,构建杂交配套系以培育优良品种。从形态上看,印度养殖种群体个体大,而三亚野生种群体个体小;三亚野生种群的壳宽系数为0.18,大于印度养殖种群的0.15,三亚野生种群的贝体外形较凸,而印度养殖种群的贝体外形扁平。三亚野生种群的壳重指数(25.30)大于印度养殖群体(18.80)。通过成像色度检测分析系统分析,每个种群都有自己的颜色特征值——三刺激值和颜色参数;比较两个种群颜色参数Lab时表明,三亚野生种群贝壳珍珠质颜色的明度(L)大于印度养殖种群,色品比印度养殖种群更偏向绿色(-a)和黄色(b),印度养殖种群色品偏向蓝色和红色。两个种群间贝壳珍珠质的色差(△XEab)为10.69,属于大色差,感觉强烈。

关 键 词:马氏珠母贝  地理种群  形态性状  珍珠质颜色

Abstract:pearl oyster, lected as bas system with weight index In our "Pearl Oyster Breeding scheme, POBs", two geographical populations of Pinctada martensii from India (IN) and Sanya (SY,China), respectively, were seic populations to establish two specialized lines and to constitute a hybrid breeding heterosis. Morphologically, IN is larger than SY. Both the shell width and shell of IN were higher than SY (0.18 versus 0. 15 and 25.30 versus 18.80, respectively). SY had a large convexity, while IN appeared a little bit flat. The Imaging and Colour- Measuring Analysis demonstrated that the colour of shell nacre from each population had unique tri-stimulus value and parameter of colour. Compared with parameters of colour (Lab) between the two populations, the lightness of SY was brighter than IN, and chromaticity in SY tended to green (-a) and yellow (b), while it tended to be blue and red in IN. Colour difference (△Eab)of the shell nacre between the two populations was 10.69 and was of significant difference.
Keywords:Pinctada martensii Geographical populations Morphometrics Shell nacre colour
