Summary The genetics of quantitative characters, namely, fruit shape, fruit weight, period from seeding to flowering, bunchiness and hairiness have been studied withGriffing's method of the constant parent regression analysis. There are arithmetically cumulative action with negative dominance in respect to genes for shape, and the genes for the period from seeding to flowering. The degree of dominance of genes for shape is very slight. The degree of dominance is highly variable in the genes for the length of the period between seeding and flowering, in some crosses even overdominance may be observed. In the case of the genes for weight a more adequate model of gene actions is logarithmic. The genes for bunchiness show no dominance so far as the present experiment is concerned, and the genes for hairiness show negative dominance.
