PHENOTYPICAL PERFORMANCES AT 5 CYPRINUS CARPIO LINES RESULTING FROM GALITIAN VARIETY GENITORS SELECTED ON DNA FINGERPRINTING AT 45 AND 145 DAYS

Abstract

The paper presents some phenotypical performances of five offsprings families who belong to five lines created in Cyprinus carpio population, Galitian variety, at Arinis fishery complex, Maramures county. We observed the total body length (from top of nose to tail’s end), the tail base length (from top of nose to tail’s base), maximum height, body weight. The data were statistical analyzed using the average and dispersal indices and the differences were tested using Student test. There are significant differences at all the observed traits, between the offsprings obtained from the parental couples matched after DNA fingerprinting using PCR-RAPD technique and migration on polyacrylamide gel. There is also observed a homogeneity between the families offsprings, as well as a variability quite big between the families, which allows a good intra- and interlinear selection, useful for the lines consolidation. The performance values are shown at the ages of 45-47 days and 145-147 days, on 100 offspring per family, randomly captured for the representability of the extraction population.
