摘要

Crossbred layer chickens derived from a diallele crossed F_1 population were selected as a parental stock. Artificial inseminations were performed to generate F_2 progenies. The traits of the F_2 population considered Were the age of first egg (AFE), the average egg weight at 262 days of age (EW), and the egg number at 262 days of age (EP). The data were analyzed for genetic parameters using 2 method; the least squares by analysis f variance (ANOVA) and the restricted maximum likelihood (REML).
