Abstract以壳长为标准,在菲律宾蛤仔生长速度快的家系中选择大、小两种规格蛤仔,上选雌性个体为A、雄性为B;下选雌性个体为a、雄性为b,采用双列杂交方法,分别建立AB、Ab、aB、ab4组近交家系。测量并统计分析各近交家系的幼虫期和稚贝期的壳长生长及变态情况。结果表明:近交家系的生长顺序为AB>Ab>aB>ab,除9日龄外,AB与ab的壳长生长差异显著(P<0.05)。随着日龄的增加,AB逐渐体现出明显的生长优势,在90日龄时与其它三个家系的生长差异明显(P<0.05)。杂交组Ab的生长优于aB,表明菲律宾蛤仔前期的生长也受母本效应的影响。从6日龄起,各近交家系开始附着变态,AB的变态率为71.12%1....
