Breeding Vines: Unlocking the Grapevine Pollination Dynamics and Potential for Hybridization in Temperate Region of Kashmir Valley

AbstractGrapevine reproductive biology plays a crucial role in viticulture success, yet research specific to the Kashmir region remains limited. This study investigated pollination and hybridization characteristics across three grape varieties (Sahebi, Thompson Seedless, and Fantasy Seedless) over two growing seasons viz., 2022 and 2023 in Kashmir, India. The research examined key reproductive parameters including pollen viability, stigma receptivity, pollen germination, and fruit set. Results demonstrated significant varietal differences across all parameters, with Sahebi consistently outperforming other varieties. Sahebi exhibited superior pollen viability (82.13%), stigma receptivity (84.73%), pollen germination (73.27%), and fruit set (61.72%). These findings provide valuable insights for grape breeding programs in Kashmir and contribute to the optimization of commercial grape production in the region. The study highlights Sahebi’s potential as a superior variety for both breeding and commercial cultivation, offering practical implications for improving grape yield and quality in temperate climates.
