Developing of Seedless Grape Varieties

In this study, it was planned to identify the seedless genotypes by screening with molecular markers for early selection among the F1 genotypes obtained in the hybridization study. In addition, it was aimed to determine the appropriate sampling time by applying the embryo rescue technique for F1 genotypes obtained from these combinations in which seedless varieties were used as the female parent. When the conversion rates into plants were examined, 50% success was achieved in the Yalova Seedless X Glenora combination, while this rate was 62.5% in the Yalova Seedless X Philipp combination. In the study, F1 genotypes obtained from these were screened with the VvAGL11 marker. When the appropriate sampling times were examined, while the 8th week was prominent in the Yalova Seedless X Philipp combination, the best results were obtained from the samples taken at the 9th week in the Yalova Seedless X Glenora combination
