QTL mapping and underlying genes for heat tolerance in grapevine (Rhine Riesling × Cabernet Sauvignon) under field conditions.

ABSTRACT:

Key message

QTL analysis for key physiological traits assessed during hot days highlighted 26 genomic regions and promising candidate genes for thermotolerance and response to light stress under field conditions in grapevine. Grapevine is one of the most widely cultivated perennial fruit crops in the world, with its economic relevance mainly related to wine production. Climate change, with global warming and increased frequency of intense phenomena, is greatly affecting viticulture and the wine sector. Thus, studying the genetic factors involved in grapevine response to high temperatures can help to improve vineyard management strategies and support plant breeding innovations. In this experiment, a mapping population (Rhine Riesling × Cabernet Sauvignon) was used to perform a genet
