More than 10,000 seedlings were studied to elaborate the mode of inheritance of seedlessness in grapes (Vitis spp.). Self-pollinations of seeded selections having seedlessness in their parentage gave 0 to 10.7% seedless progeny. Crosses between seeded selections with seedlessness in one or both parents gave similar proportions. Crosses of seeded × seedless selections gave 0-55% seedless. Results were extremely variable, without apparent correlation to normal genetic ratios. Seedlessness appeared to be largely controlled by recessive factors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
