瓯江彩鲤体色与生长的遗传-环境互作分析

对五种体色的瓯江彩鲤进行稻田、网箱和水泥池生长对比试验,探讨体色与生长的遗传-环境互作。结果表明:瓯江彩鲤的体色与生长率存在一定程度的互作效应,在稻田中,“全红”和“麻花”彩鲤的生长率显著地高于其它三种体色(P<0.05);在网箱中,“大花”、“粉玉”和“粉花”彩鲤的生长率显著地高于“全红”和“麻花”彩鲤(P<0.05);在池塘中,“大花”彩鲤的生长率极显著高于其它四种体色彩鲤(P<0.01),而其它四种体色彩鲤的生长性能不存在显著差异(P>0.05)。由此认为,“全红”和“麻花”彩鲤比较适合稻田饲养,“大花”、“粉玉”和“粉花”彩鲤比较适合网箱或池塘饲养。“粉花”彩鲤与环境的互作效应最大。

Genotype-environment interaction analysis from the body color and growth character in Oujiang color common carp,Cyprinus carpio var.color

The growth experiments on 5 color patterns of Oujiang color common carp ( Cyprinus caipio var. color) reared in paddies, net cages and concrete tanks were conducted to analyze the genotype - environment interaction from body color and growth character. The result indicated that the genotype-environment interaction was detected in Oujiang color common carp. At paddy field environment, AGRW and IGRW of "whole red" and "red color with small black spots" were significantly higher than those of the other three kinds of color patterns (P < 0.05); at net cage environment, AGRW and IGRW of "red color with big black spots", "whole white" and "white color with big black spots " were significantly higher than those of "whole red" and "red color with small black spots"( P < 0.05); at concrete tank environment, AGRW and IGRW of "red color with big black spots" were significantly higher than those of other four kinds of color patterns ( P < 0. 01), but the other four kinds of color patterns had no significant difference ( P > 0.05). "whole red" and "red color with small black spots" would be more suitable to be reared in paddy field, "red color with big black spots", "whole white" and "white color with big black spots" would be'more suitable to be reared in concrete tank and net cage than other color patterns; "white color with big black spots" was detected with the most obvious genotype-environment interaction.
