Natural genetic variation for fruit set rate within Malbec grapevine (Vitis vinifera L.) clones

Fruit set is the transformation of flower ovaries into berries. Fruit set rate determines the number of berries produced per bunch, which is a major component of yield in grapevines. Malbec is a black-berried grapevine cultivar recognized for producing high-quality wines, and particularly relevant f...

Sumario:Fruit set is the transformation of flower ovaries into berries. Fruit set rate determines the number of berries produced per bunch, which is a major component of yield in grapevines. Malbec is a black-berried grapevine cultivar recognized for producing high-quality wines, and particularly relevant for Argentina's winemaking industry. Clonal variation has been reported for Malbec at the phenotypic and molecular levels. However, less is known about clonal variation for agronomically relevant features affecting yield. In this work we evaluated 25 Malbec clones for the fruit set rate and other related features over multiple seasons.
