Seed and Germination Characteristics of Different Hybrids Belonging to Vitis Species

Abstract

In this research, some grape cultivars are belonging to Vitis vinifera, Vitis labrusca, and interspecific grape cultivars were used for crossbreeding. The aim of the cross-breedings was to obtain individuals that could be used as a table grape, female flower type genotypes, and would be resistant to disease and cold hardy grapes. In the research, berry set (seeded and seedless berry number), seed weight (g), seed width and length (mm), floating empty seed rate (seed viability, %), seed germination rates (%), seedling survival rates (%) and shoot length (cm) were calculated in the seeds obtained as a result of cross-breeding. In this research, as a result of crossbreeding with different Vitis species and hybrids, the germination rate was significantly higher, especially when using ‘Red Globe’ and ‘Cayuga White’ cultivars as maternal parents. Although the germination rates of the seeds obtained after cross-breeding are low, the use of ‘Çavuş’ grape cultivar with female flower form in cross-breeding facilitates the work since emasculation is not necessary. It would be appropriate to increase the number of grapevines with female flowers type in breeding studies.
