Heritability Estimates of Growth-Related Traits in Oriental River Prawns, Macrobrachium nipponense

Breeding programs in oriental river prawn populations would benefit from a knowledge of heritabilities for growth-related traits to assess their potential genetic improvement. This study reports the results heritability estimation and evaluation epistatic interactions (Macrobrachium nipponense). The showed that estimates (h2) were low medium magnitude, ranging between 0.10 (±0.02) 0.22 (±0.01) females 0.08 0.26 males. additive × epistasis was directional synergistic body weight (growth), length, two processing (abdominal meat abdominal percentage). presence biallelic provides additional new information formulation selection programs. Elimination some sources nonadditive effects phenotypes can lead more accurate evaluations, desirable gains could be achieved through integration heritability, (breeding values), prawns.
