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

Abstract:

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.
