Method: General evaluation of the Daucus Collection. Data was recorded in Ames, Iowa by the staff of the North Central Regional Plant Introduction Station. | |
Traits evaluated: HUNDRED SEED WEIGHT (100SEEDWGT) Method: This is the generic evaluation method that can be used for transferring hundred seed weights from the prod.nc7iv table to the prod.ob table. The prod.ob table is where the values for the descriptors are stored. | |

This study was designed to estimate ion leakage and increase in cell permeability in response to heat stress at the early and late seedling developmental stages of 215 diverse accessions of wild and cultivated carrot germplasm. | |
The objectives of this study were to evaluate the response of diverse carrot germplasm to salinity stress, identify salt-tolerant carrot germplasm that may be used by breeders, and define appropriate screening criteria for assessing salt tolerance in germinating carrot seed. | |
The objectives of this study were to evaluate the response of diverse carrot germplasm to heat stress, identify heat-tolerant germplasm that may be used by plant breeders, and define the appropriate temperature for assessing heat tolerance in germinating carrot seed. | |
This study was designed to define the appropriate osmotic potential for evaluating drought tolerance in carrot, to evaluate the response of diverse carrot germplasm to drought stress during seed germination to identify drought tolerant accessions that may be used by plant breeders, and to evaluate the relation between amylase activity and germination rate of drought tolerant and sensitive accessions. | |
This study is the first field-based, multi-year experiment to evaluate shoot-growth trait variation over a 100-day growing season in a carrot diversity panel (N=695) that includes genetically diverse carrot accessions from the United States Department of Agriculture National Plant Germplasm System. This study provides the first broad-sense heritability estimates for early-season seedling vigor and early-season canopy coverage on a diverse collection. We also develop a method for characterizing flowering to identify accessions that are predominantly biennial, which could be incorporated into biennial breeding programs without substantially increasing the risk of annual growth habits. |
