The purpose of the present investigation was to estimate variances of general and specific combining ability, maternal effects and reciprocal effects for inbred line crosses. The data were provided by a commercial poultry breeding farm. Percent hatch of all eggs, percent brooder house mortality, age at 50% egg production, 165-, 269-and 300-day hen-housed percent egg production, hen-day total egg production, egg weight and percent laying house mortality were studied.
