Abstract
Consumers are waiting for constant improvement of nutritional and sensorial quality of fruits and vegetables.
Specialized metabolites are a priority target to improve the quality of plant products due to their nutritional and sensory attributes.
Among vegetables, carrot is distinguished by its ability to accumulate a wide range of metabolites in root, including polyacetylenes, carotenoids and sugars.
Therefore, carrot may be considered as a root plant model to better understand the involvement of biochemical compounds in vegetable quality.
Ensuring a guaranteed content of these metabolites, considering their respective sensory and nutritional attributes, is crucial to achieve an optimal quality in carrot crops.
The purpose of this work is to develop an integrative approach, including different cultivars and multi-environment trials, to grasp the respective influence of different factors in the accumulation of compounds of interest.
By focusing on biochemical compounds with organoleptic and nutritional attributes, this study aims to create a typology and thus identify agronomical levers to ensure a guaranteed content of metabolites of interest in carrot crops.
Beyond a better appreciation of phenotypic plasticity levels obtained by variation analyses, the identification of leading environmental factors related to key metabolites content was done using PLSr models.
A sequential approach was used considering the whole crop cycle and the different development stages of carrot.
This work paves the way for a better mastering of carrot quality and address recommendations for breeders and growers.
