Research Project: Screening Diverse Carrot Germplasm for Improved Germination and Seed Characteristics

Location: Vegetable Crops Research

Project Number: 5090-21000-073-061-I
Project Type: Interagency Reimbursable Agreement

Start Date: Jun 15, 2021
End Date: Jun 14, 2023

1) Measure variance of seed size within and between carrot accession, and map associated loci with GWA analysis 2) Calculate correlation between seed size and germination-percentage, time-to-germination and consistency in non-salt-stressed and salt-stressed germination conditions. 3) Test if larger seed size results in faster or greater growth carrot growth in field environments.

1) Seed increase of 700 carrot accessions in controlled environment 2) Next-gen sequencing to generate genotypes for 700 carrot accessions 3) Digitally measure seed size and complete GWA analyses 4) Petri-dish germination assays for 700 carrot accessions and complete GWA analyses 5) Grow subset of lines in field to compare controlled environment and field results.
