Abstract:

This study evaluated the performance of various grape hybrids for yield and quality traits, and to identify hybrid vigor for specific traits that can be utilized in future breeding programs. The research involved evaluating 76 hybrids derived from two diverse parents i.e., Pinot Noir and Marselan, during 2021 and 2022. Multiple fruit yield and biochemical traits were examined and quality traits of peel, flesh, and seeds were recorded. Two-way analysis of variance for parents was performed for all the traits under study to understand the significance of these traits over two years. Likewise, statistical analysis, such as the coefficient of variation, combined transmissibility rate, heterosis, and heterobeltiosis were computed to compare the performance of the hybrids against mid and better parents. The highest CV and Ta values were observed for fruit yield and peel phenolic contents respectively, across both years. The two-year data suggested that certain hybrids displayed superior heterosis and heterobeltiosis for numerous individual traits. Hybrid number 7 exhibited negative hybrid vigor for most of the traits and must be avoided for general cultivation. while hybrid number 25 showed increased hybrid vigor fruit yield and total flavonoids in peel, flesh, and seeds as well as a higher concentration of tannins in seeds. This research underscores the potential of hybrid number 25 for grape farmers and the wine industry in China, hinting at the untapped potential of hybrid grapes in producing superior wines. The study's insights aim to aid the development of indigenous grape varieties, reducing China's reliance on imports and fostering a unique Chinese wine identity in the global market. The data derived from this two-year evaluation can guide future breeding programs and further exploration of grape hybrid vigor to optimize both yield and wine making quality.
