The Effect of Feeding Level and Genetic Background on Sex Determination in XX;mas-1/mas-+ Common Carp (Cyprinus carpio L.)
摘要
Abstract
The effects of feeding level and genetic background on sexual determination of XX; mas-1/mas-+ common carp (Cyprinus carpio L.) were investigated. The effect of feeding level on a F1 hybrid of E4×E5 (XX;mas-+/mas-+ × XX;mas-1/mas-1) clone was highly significant, high feeding level (HFL) groups contained 51.5% females while only 4.l % females were found in the low feeding level (LFL) groups. In the backcross of a F1 hybrid of E45×E5 (XX;mas-1/mas-+×XX;mas-1/mas-1) clone, genetic background was more important than feeding level. In both treatment groups only 1~2 females were found. The third progeny was a backcross of F1 hybrid of E4×E45 (XX;mas-+/mas-+×XX;mas-1/mas-+) clone,the frequency of females in the HFL groups (86.2% and 76.8% respectively) was significantly different from those of one LFL group (76.8 %) but not of the other (57.9%). There was no significant difference in the rate of sex reversal of XX; mas-1/mas-+ common carp between the E4×E5 and the E4×E45 offspring at both feeding levels.关键词
