Acta Oceanologica Sinica, 34(2): GENETIC VARIATION IN BODY WEIGHT OF LITOPENAEUS VANNAMEI IN DIFFERENT GROWTH STAGES YUAN Rui-Peng, LIU Jian-Yong, HU Zhi-Guo, ZHANG Jia-Chen (Fisheries College of Guangdong Ocean University, Zhanjiang , China) Abstract We studied the genetic variation in body weight of Litopenaeus vannamei in different growth stages from postlarvae (S1), juvenile (S2), adult (S3), to broodstock (S4). Additive and dominant genetic mode and statistical methods were applied. The results show that the components of unconditional additive variance were nearly 0 in S1 and S2, and and in S3 and S4, respectively. The conditional addition variance was ±0.0101, ±0.0342, ±0.4847, and ± all at highly significant level (P<0.01) in S1 to S4, respectively. The contribution of the unconditional additive variance to phenotypic variance was 8.06%, 0.98%, 11.31%, and 24.64%, and that of the conditional one was 8.13%, 1.20%, 36.12%, and 29.58% in S1 to S4, respectively. Of the accumulated effect, the dominant effect took 88.67%, 98.66%, and 85.05% in stages S1 to S3, respectively, but in S4, additive gene effect contributed for 60.44%. In S1 and S2, the net dominant effect controlled the body weight trait by taking 88.67% and 98.16%, while in S3 and S4, net additive effect played the role accounting for 70.39% and 88.57%, respectively. Therefore, in early stages of L. vannamei grow-up, the additive effect of body weight trait was the main effect and expressed increasingly, while in late stages, the dominant effects overtook, implying that selective hybridization can effectively improve the body weight trait of the shrimp. Key words Litopenaeus vannamei; body weight; genetic variation; additive effect; dominant effect
