| Sumario: | Cultivar diversification and increasing carrot functional value are among the main objectives of the Argentine carrot breeding program at INTA La Consulta (Mendoza). In this context, purple carrots, which originated in the Middle East, are of interest, since some genotypes can accumulate large amounts of anthocyanins in their roots and other plant organs. These pigments are well-known for their health-promoting properties and they are also used as dyes in the food industry. Anthocyanin chemical structure affects their chemical stability and biological properties. Acylated anthocyanins (AA) present higher chemical stability and therefore are more suitable as food dyes than non-acylated anthocyanins (NAA). However, the latter (NAA) have much higher bioavailability, and therefore are of greater for fresh-carrot consumer, from a health-promoting perspective. In this context, it is of interest for the carrot breeding program to develop purple carrot cultivars with high AA, for the production of natural food dyes, and cultivars with high NAA, for fresh consumption. To this end, this project will characterize the purple carrot germplasm for their root anthocyanin content and composition, with the goal of identifying and selecting valuable genotypes suitable for production purposes, fresh consumption and natural food dyes. Variation in anthocyanin composition between the root phloem and xylem tissues and leaves will also be examined. In addition, environmental influence due to agroclimatic conditions on this trait will be investigated. The expected results from this project will allow the identification of valuable materials and optimal growing conditions for the production of purple carrots for fresh consumption and food dyes. |
