Heritability estimates for processing and quality traits in common carp (Cyprinus carpio L.) using a molecular pedigree

摘要: Abstract Heritability estimates with a microsatellite parentage assignment based pedigree are of special interest in common carp cultured under traditional pond conditions. This method reduces environment effects as all families can be grown immediately after hatching mixed the same pond. We applied this to study genetics growth and processing traits at market size (1.5 kg more). The experimental progeny was established by crossing 147 two-year old males 8 females (six eight-year old) Hungarian synthetic mirror population. fish grew up through three vegetation seasons end sample 331 examined for biometrical (standard length, body weight, relative head height, width), percent fat (% processed body, % fillets skin, without skin). It shown that sex had significant effect on most traits: were larger fatter than males, they both higher fillet skin. Standard length high heritability (> 0.5), while width, yields medium (0.2–0.5). found relatively positive genetic correlations between weight) (0.71 0.59, respectively), favourable (0.69 standard 0.74 (0.50–0.77). Genetic shape (relative height width) weak moderate, thus selection better should have little impact towards more rotund shape. Relative strong negative correlation (− 0.7 − 0.9) fat, yields. means indirect reduced effective improving yield.
