我国科研人员研制的“黄海1号”中国明对虾养殖新品种通过了技术鉴定。该品种表现出生长速度快、抗逆能力较强的优良性状。规模养殖试验群体的体长比对照平均增长8.40％,体重增长26.86％,养殖成功率超过90％,而未经选育的对照池养殖成功率不足70％。通过采用同工酶电泳技术、RAPD技术、微卫星DNA技术以及线粒体DNA分析等研究了不同选育世代的遗传变异,进行了与生长速度相关的遗传标记的筛选,已初步找到8个可能与生长性状相关的分子遗传标记。分子
China’s scientific research personnel to develop “Huanghai No. 1 ” China Ming shrimp breeding new varieties passed the technical appraisal. The variety showed good growth rate, strong resistance to adverse traits. The body length of large-scale aquaculture test population was 8.40% higher than the control, 26.86% weight gain, more than 90% aquaculture success rate, while the success rate of control aquaculture without breeding was less than 70%. The genetic variations of different breeding generations were studied by isozyme electrophoresis, RAPD, microsatellite DNA and mitochondrial DNA analysis. The genetic markers related to the growth rate were screened. Trait-related molecular genetic markers. molecular
