Efficacy of selection in sexually breeding Artemia (Artemia franciscana, Kellogg, 1906)

摘要

Bi-directional selection for smaller naupliar sizeud(SNS) and bigger naupliar size (BNS) was practicedudto develop two divergent lines. The e⁄cacy of bidirectionaludmass selection in Artemia franciscana wasudevaluated by comparing the predicted genetic gainsudwith the realized genetic gains. Two sets of predictionsudwere made using two heritability estimates,ude.g., the heritability estimate from full-sib analysisud(h2) and the estimate from regression of o¡spring onudmid parent (bop). Predictions with the full-sib heritabilitiesudwere of very high magnitude as comparedudwith predictions with bop heritabilities.
