      • Abstract
    • Analysis with methods of quantitative genetics and statistics was done on thereults of 36 hybrid combinations from 6 parental varieties in complete dialledcrossing.There was variation in the occurrence of unlaid egg both among par-ents and F1.The number of the unlaid eggs depended on the geneticcombination. The figure in Japanese hybrid tended to be higher.The analysisshowed that there was no corelationship between fecundity and unlaid egg ra-tio.If the unlaid egg ratio was high in the parents,the same would happen intheir off springs.The inheritance of the unlaid egg ratio is super-dominant,withdominant effect greater than additive effect.The frequency of donunant genes washigher than that of recessive genes in the parents.It is soggested that the nulnber ofgenes is 3 pairs.
