Hybrid Vigor in Egg-Plants and Its Practical Utilization

“…He said that "if the pollen parent is of a light and white-seeded race, while the mother parent is a colored and heavy-seeded one, then the FI seeds will be more or less intermediate." WINGARD (1927), making reciprocal crosses of six combinations of bean varieties, found a marked increase in weight of the F1 seed in one of these crosses, while in its reciprocal cross and the crosses of the other five combinations, no apparent difference was seen from the selfed seeds of the mother parents. I n the particular cross just mentioned, the selfed seed of the mother parent had an average weight of 0.694 gram and that of the pollen parent 0.420 gram, while the F1 seed had an average of 1.076 grams.…”
