Research Project: Applying Advanced Phenotypic and Genomic Tools to Improve Flavor, Nutrition, and Production Traits in Carrot (Wisconsin)

Location: Vegetable Crops Research

Project Number: 5090-21000-073-083-A
Project Type: Cooperative Agreement

Start Date: Sep 15, 2022
End Date: Aug 14, 2026

Objective:
Obj. 1 - Develop cost-effective genomic tools to advance breeding populations and integrate loci related to economically significant traits identified by stakeholders. Obj. 2 – Using multi-parental and bi-parental populations to map location(s) of genes underlying economically important traits using an optimized genomic-assisted strategies from Obj 1. Obj. 3 - Evaluate bioavailability of nutrients in selected breeding stocks with varying nutrient composition that may influence bioavailability (e.g., greater nutrient content, mixtures of carotenoids and anthocyanins).

Approach:
1- Identify single nucleotide polymorphisms and structural variants representative of genetic diversity in diverse germplasm and elite breeding lines; 2 – Conduct field trialing of genetic mapping populations created from crosses with elite breeding lines and landraces for economically important traits with complex genetic inheritance including resistance to root knot nematode and cavity spot, bolting resistance, flavor, pigments, and seedling vigor. 3 - Evaluate high and low carotenoid and/or anthocyanin bioavailability in carrot lines with methods we have established.
