[目的]研究马氏珠母贝(P.f.martensii)“海选1号”的生长性状.[方法]测定并比较马氏珠母贝(P.f.martensii)“海选1号”养殖品种和对照养殖群体的受精率、孵化率和变态率及不同月龄生长数据.[结果]“海选1号”和对照群体的受精率没有显著性差异(P＞0.05),“海选1号”的孵化率和变态率显著高于对照群体(P＜0.05);3日龄和5日龄“海选1号”幼虫的存活率和对照组不存在显著性差异(P＞0.05);10日龄、15日龄和20日龄“海选1号”幼虫的存活率显著高于对照组(P＜0.05);3日龄“海选1号”幼虫的壳长和壳高与对照组差异不显著(P＞0.05);5日、10日龄、15日龄、20日龄“海选1号”幼虫的壳长和壳高均显著大于对照组(P ＜0.05);40日龄、100日龄、150日龄、250日龄和360日龄“海选1号”稚贝的壳长和壳高均显著大于对照组(P＜0.05).[结论]马氏珠母贝“海选1号”较对照养殖群体具有较好的生长优势.该研究为马氏珠母贝育种工作和产业应用提供了基础数据.%[Objective] Growth traits of Pinctada fucata martensii Haixuan No.1 were studied.[Method] Fertilization rate,hatching rate,meta-morphosis rate and growth traits at different months of Pinctada fucata martensii" Haixuan No.1" and control groups were measured and compared.[Result] There was no significant difference in fertilization rate between "Haixuan No.1" and control groups (P ＞ 0.05),but the larval hatching rate and metamorphosis rate of "Haixuan No.1" were significantly higher than that of control groups (P ＜ 0.05).At days 3 and 5,no significant differences were found in the larval survival rate between "Haixuan No.1" and control groups,but survival rate of "Haixuan No.1" was significantly higher than that of control groups at days 10,15 and 20 (P ＜0.05).At days 3,the larval shell length and shell height did not significantly differ between "Haixuan No.1" and control groups (P ＞ 0.05),but shell length and shell height of "Haixuan No.1 "showed significantly higher than that of control groups at days 5,10,15 and 20 (P ＜0.05).Similarly,at days 40,100,150,250 and 360,shell length and shell height of "Haixuan No.1 "observed significantly higher than that of control groups (P ＜ 0.05).[Conclusion] "Haixuan No.1 "exhibited better growth performance than control groups.This can provide a basis for breeding work and industrial applications of P.f.martensii.
