| Abstract: | Growth performance was compared in four groups of F1 generation of Macrobrachium nipponense from Taihu Lake(T) and Poyang Lake(P) populations by complete diallel crosses.The results showed that the group of F1 generation from T(♀)×P(♂)(TP) had the largest body length and weight gain and the fastest growth speed,which were significantly larger and faster than those of P(♀)×T(♂)(PT) and inbreeding groups.The coefficient of variation of PT group in length and weight increased accompanying with the increase of month age,while the growth coefficient of variation and discrete degree of TP group always kept lower among four groups.The correlation of body length and weight accorded with the power function W=aLb with very high relativity.The relation of body length and weight inrcease accompanying with farming time met exponential relationship L/W=ced△t,and the related coefficient of TP and PT groups was significantly higher than that of inbreeding ones.All of above,the obvious heterosis in growth performance could be achieved through the cross of M.nipponense populations between Taihu Lake(♀) and Poyang Lake(♂). |
