Morphometric variations analysis of Cyprinus carpio var. jian, Cypri-nus carpio haermatopterus and the reciprocal F1 hybrids (Cyprinus carpio var. jian♀×Cyprinus carpio haermatopterus♂, Cyprinus carpio var. jian♂×Cyprinus carpio haermatopterus♀)

Abstract
The morphological variations between common carp Cyprinus carpio var. jian, Cyprinus carpio haermatop-terus and the reciprocal F1 hybrids(Cyprinus carpio var. jian♀×Cyprinus carpio haermatopterus♂, and Cyprinus car-pio var. jian♂×Cyprinus carpio haermatopterus♀) were studied by variance analysis and by three methods of multi-variate analysis, based on their morphological characters. There were no significant differences among four groups based on the number of scales on the lateral line, scales above the lateral line, scales beneath the lateral line, spines of pectoral fins and ventral fin(P>0.05) except for the number of spines of the dorsal fin, anal fin, and soft rays of the dor-sal fin, anal fin, ventral fin and pectoral fins. The cluster results showed that the morphological traits were similar be-tween the parent fish stocks, but quite different from those of the reciprocal F1 hybrids. The discriminant functions of the four stocks were established, and the discriminatory accuracies were 76.7%-96.7%(P1)and 85.2%-90.6%(P2).The total discriminatory accuracy was 87.5%. In the principal component analysis, nine principal components were con-structed, and the cumulative contributory ratio was 68.94%. The study would be beneficial for identifying groups, and for determining genetic relationships and breeding.关键词
