摘要
对罗氏沼虾(Macrobraciumrosenbergii)四个选育系——新引进系、原引进系、正交系和反交系,进行了养殖对比研究。研究结果表明:新引进系的生产性能最优,试验池单位养殖产量比反交系增产3·40%,比正交系增产8·35%,比原引进系增产12·16%;试验塘单位养殖产量比反交系增产21·24%,比正交系增产27·60%,比原引进系增产11·12%;杂交系的杂种优势不明显。
A comparative study on culture effects of four different strains of Macrobrachium rosenbergii （ new introduced strain, former introduced strain, positive hybridized strain and reverse hybridized strain）was conducted in this paper. The results indicated that the new introduced strain had the most productive capability. In the test basin, the yield of the new introduced strain was 3.40% higher than the reverse hybridized strain, 8.35% higher than the positive hybridized, and 12. 16% higher than the former introduced strain. In the test pond, the unit yield of the new introduced strain was 21.24% higher than the reverse hybridized strain, 27. 60% higher than the positive hybridized, and 11.12% higher than the former introduced strain, and the heterosis of the hybridized strain is not distinctive.
