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. | |
Accessions were planted in a randomized complete block design with two replications at the Hancock Research Station in Hancock, WI, in the summer of 2016 and 2017. One hundred seeds of each accession were planted in each 1-m plots. Canopy height was measured just before harvest with three measurements taken per plot. Harsh flavor was evaluated on a scale of 1 to 5 (with 5 being the least harsh, and 1 being the harshest) on at least three individual roots per plot after harvest in fall 2016. | |
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. | |
Traits evaluated: LEAF TYPE (LEAFTYPE); MATURE LEAF LENGTH (MATLEAFLEN); MATURE LEAF WIDTH (MATLEAFWID); MATURE PETIOLE LENGTH (MATPETLENG); MATURE PETIOLE THICKNESS (MATPETTHK); PETIOLE HAIRINESS (PETIOLHAIR) Evaluation location: Iowa, United States. Method: Daucus descriptor data recorded from observation planting at the NCRPIS farm (42 degrees 3 minutes N latitude 93 degrees 30 minutes W longitude). |
