| 摘 要： | The inability of Fenneropenaeus chinensis to tolerate low temperatures is of major economic concern in temperate climates,as it reduces their growing season and leads to over-winter mortality.In this study,the heritability of body weight under low grow-out temperature and cold tolerance in F.chinensis were first investigated and estimated using 88 ful-sib families,which might provide crucial information in Chinese fleshy prawn breeding programs.The heritability for body weight under suitable and low temperature of F.chinensis were both moderate(0.158 0±0.307 5 and 0.132 0±0.026 9 respectively);the large coefficient of variation(approximately 21%) and moderate estimate of heritability for body weight indicated substantial potential for selective breeding.The heritability estimate for cold tolerance was low(0.019 2±0.023 5),and showed no significant differences from zero(P0.05).A weak genetic correlation between cold tolerance and body weight was also estimated in the present study,also showing no significant differences from zero(P0.05).Thus,more research needs to be conducted on the more accurate heritability estimate of cold tolerance and genetic correlations between traits in F.chinensis to further improve the achievement of breeding goals.

| Abstract: | The inability of Fenneropenaeus chinensis to tolerate low temperatures is of major economic concern in temperate climates, as it reduces their growing season and leads to over-winter mortality. In this study, the heritability of body weight under low grow-out temperature and cold tolerance in F. chinensis were first investigated and estimated using 88 ful-sib families, which might provide crucial information in Chinese fleshy prawn breeding programs. The heritability for body weight under suitable and low temperature of F. chinensis were both moderate (0.158 0±0.307 5 and 0.132 0±0.026 9 respectively); the large coefficient of variation (approximately 21%) and moderate estimate of heritability for body weight indicated substantial potential for selective breeding. The heritability estimate for cold tolerance was low (0.019 2±0.023 5), and showed no significant differences from zero (P>0.05). A weak genetic correlation between cold tolerance and body weight was also estimated in the present study, also showing no significant differences from zero (P>0.05). Thus, more research needs to be conducted on the more accurate heritability estimate of cold tolerance and genetic correlations between traits in F. chinensis to further improve the achievement of breeding goals. |
