MARGUERIT Elisa

Elisa Marguerit is a research professor in viticulture at Bordeaux Sciences Agro. Her teaching focuses on viticultural practices such as fertilization and vigor management, experimentation and statistics applied to viticulture, and quantitative genetics. Her research activities aim to study the responses induced by grapevine rootstocks and to identify the genetic architecture of adaptive traits. An agricultural engineer, she obtained her PhD in 2010 on the genetic architecture of grapevine rootstock-induced responses to water deficit. A genetic region has been identified as being involved in the water extraction capacity of rootstocks. She coordinates an experimental set-up that is unique in the world: the GreffAdapt plot. This experimental set-up consists of 55 rootstocks grafted onto 5 scions. The aim is to characterize rootstocks used abroad and to revisit rootstocks not widely used in France, in order to diversify the range of products available to professionals in the industry. This approach is complementary to that of varietal creation, which it tackles by creating new crosses and by studying Vitis berlandieri in particular.
