Recent Developments in Seedless Grapevine Breeding

Abstract

Grapes are one of the most commonly produced fruit crops in the world and are consumed as table grapes, wine grapes and dried grapes. In line with consumer demands, seedlessness continues to be an important feature that increases the chances of marketing grapes. Nearly all of the dried grapes that are offered to the world markets are seedless grapes. In addition, the demand for seedless varieties has increased steadily in the table grape trade over the years. Therefore, the production of new seedless grape varieties with large berries that are suitable for table consumption is one of the important goals of breeding studies in viticulture. In this study, recently bred and released new seedless grape varieties are briefly introduced, seedless grape breeding methods are summarised, and the latest developments in breeding methods are explained.

Impact of Methyl Jasmonate, Abscissic Acid and Ethephon on the Consistency of Flame Seedless Grapes Pre-harvest and Post-harvest

“…It is a robust grape cultivar with a heavy bearing ability which also remains well in storage. It is a hybrid of several cultivars of (Vitis vinifera ), (Cardinal x Sultanina) x [(Red Malaga x Tifafihi Ahmer ) x (Muscat of Alexandria x Sultanina)] (Akkurt et al, 2019). Flame Seedless was bred in the U.S.A. in 1973.…”

Vascular Connections Into the Grape Berry: The Link of Structural Investment to Seededness

“…Unlike the seeded wine grape cultivars, seedless cultivars are popular for the table grape and dried fruit industries. The seedlessness in these cultivars, such as Ruby Seedless and Flame Seedless, is typically the result of stenospermocarpy ( Gribaudo et al, 1993 ; Akkurt et al, 2019 ), in which the embryo is aborted shortly after fertilization leaving only small seed remnants ( Pratt, 1971 ).…”

Search for donors of powdery mildew resistance genes among seedless and table grape varieties

“…Most often, the population chooses seedless grapes from table varieties for fresh consumption. Seedless grape varieties also play an influential role in the industry, as almost all dried products are made from them [2].…”
