本文以杂色鲍为研究对象，从选择育种及遗传参数的估计、杂交育种及杂种优势的利用和基因型与环境的互作三个方面阐述杂色鲍数量性状遗传与育种方面的研究。主要研究结果如下： 1．两个杂色鲍群体的歧化选择及选择效应：采用歧化选择法对两个杂色鲍群体的壳长进行了双向选择。群体A(台湾群体♀×日本群体♂)经过一代选择，上选组和下选组的生长速度较对照组分别提高和降低了12.79%和15.20%，选择效果十分显著。群体B(台湾群体♀×台湾群体♂)上选组和下选组的生长速度较对照组分别提高和降低了4.58%和5.95%，选择效果较不显著。A群体上选组和下选组壳长的现实遗传力平均值分别为0.396±0.074和0.48...In this research, quantitative tratis genetics and breeding of small abalone Haliotis diversicolor were studied in three parts: selective breeding and estimation of genetic parameters, crossbreeding among different geographically populations and genotype ×environment interaction. The main results are as follows: 1. Divergent selection for shell length in two stocks of small abalone Divergent ...学位：理学博士院系专业：海洋与环境学院海洋学系_海洋生物学学号：2112005140317
