Evaluation of some productive and reproductive crossbreeding of two different lines of common carp (Cyprinus carpio L.)

The study seems highly statistically significant differences (p<0.01) between the parentsof these two schools for the features (eggs number (thousand)/Kg life fish weight, Eggsweight(gm)/Kg life fish weight, Egg radius mm, body depth/ standard hergth ) showingsuccess Iraqi parents Carp on Hungarian parents, while the Hungarian parents carp success innumber of eggs(million)/Kg eggs . Also the result indicated that the in vesfigated productionparametes of the cultured hybrids for 5 month (total length, standard length, depth of body,depth of body / standard hergth , the average weight) highly significant differences (p<0.01)in new generation of cross-breeding Hungarian male Iraqi female . Otherwise the studyshowing the average daily increasing in body weight for the crossing of (Hungarian male ×Iraqi female), (Iraqi male × Hungarian female), (Iraqi male × Iraqi female) ,(Hungarian male×Hungarian female )whose breeding for 153 days was consequently as well as highlystatistically significant differences (p<0.01) in calculated average growth , more over there isno statistical significant differences in feed conventional factory between these crossing.
