Development and utilization of phenotyping pipelines to assess resilience to transient abiotic stress in vegetable crop populations

摘要: Climate change and associated weather fluctuations are producing both long-and short-term variability in crop growing conditions, leading to a range of chronic and transient abiotic stresses. Reproducible methods to reliably assess crop germplasm resources for resilience to these abiotic stress types are required to identify elite accessions bearing traits that can be used in breeding programmes. Abiotic stresses rarely occur in isolation, and responses to combined stresses can often not be predicted from those to individual stresses, requiring assays employing multiple simultaneous abiotic stress types. In order to identify potential breeding material of interest we have utilized populations of vegetables from the Defra funded UK VeGIN project, which include diversity fixed foundation sets (DFFSs), recombinant inbred line (RIL) mapping and half-sib populations, in order to identify resilience to transient abiotic stresses …
