Abstract

Seedless table grapes are the most preferred grapes by the consumers. Stenospermocarpy and parthenocarpy are the natural causes of seedlessness in breeding studies. The most significant characteristic of seedless grapes are their small sized and seedless fruits. Polyploidy is an alternative way to obtain seedless and large sized new table grape cultivars. Kyoho, Pione, Olimpia, Heukgoosul are some of the tetraploid grape varieties. Triploid grapes of the variaties Honey Seedless, King Dela and Mirai were obtained by hybridization of these tetraploid cvs. with diploid genotypes.
