摘　　要：以闽-粤东族大黄鱼种群为基础群体,通过开展大黄鱼体型修长、体色金黄和生长速度快的复合多性状进行群体选育,并对选育子代F2和F3的生长性能、体型、背部蓝黄值和遗传力进行测量分析。结果表明,6~24月龄的大黄鱼选育子代F2和F3的绝对增重率、体长/体高、尾柄长/尾柄高和体色均显著高于对照组(P<0.05),选育子代F2的体质量、体长/体高、尾柄长/尾柄高和背部蓝黄值遗传力分别在0.01~0.31、0.08~0.60、0.21~0.34和0.32~0.46,选育子代F3的体质量、体长/体高、尾柄长/尾柄高和背部蓝黄值遗传力分别在0.02~0.56、0.18~0.78、0.17~0.39和0.36~0.64;大黄鱼选育子代在体型、体色和生长速度上均优于对照组,且选育子代F3的经济性状较选育子代F2更具优势。结果表明复合多性状进行大黄鱼群体选育可以明显改良大黄鱼养殖群体的生长、体型和体色等经济性状。Based on the population of Min-Yuedong Larimichthys crocea,population selection was carried out by carrying out the complex characteristics of slender body size,golden body color and fast growth rate,and the growth performance,body size,back blue-yellow value and heritability of the selected offspring F2 and F3 were measured and analyzed.The results showed that the absolute weight gain rate,body length/body height,caudal stalk length/caudal stalk height and body color of F2 and F3 progeny of 6~24 months were significantly higher than those of control group(P<o.05).The heritability of body mass,body length/height,caudal stalk length/caudal stalk height and back blue-yellow value of the selected offspring F2 were 0.01~0.31,0.08~0.60,0.21~0.34 and 0.32~0.46,respectively.The heritability of body mass,body length/body height,caudal stalk length/caudal stalk height and back blue-yellow value of offspring F3 were 0.02~0.56,0.18~0.78,0.17~0.39 and 0.36~0.64,respectively.The size,body color and growth rate of the selected progeny of Larimichthys crocea were superior to those of the control group,and the economic traits of the selected progeny F3 were more advantageous than those of the selected progeny F2.The results showed that the economic traits of growth,body size and body color of Larimichthys crocea cultured population could be significantly improved by using multiple traits in Larimichthys crocea population selection.
