Seedless grapes have high commercial value and seedlessness for table grapes and raisins is one of the principle objectives of Vitis vinifera grape breeders. Recent studies have shown that the seedless trait in grapes is controlled by one major and some minor genes. The position and mapping of the major gene for seedlessness was studied in this research using Red Globe, Flame Seedless, and Thompson Seedless, together with Fl progenies from Red Globe X Flame Seedless crosses. The sequences of marker linked t...
