CucCAP scientist James D. McCreight is a contributor to the 2021 CGC report.
Melon – Breeding, Genetics, Genomics, Pathology Publications and Presentations
Germplasm collections maintained by the US National Plant Germplasm System and those of other countries are critical sources of diversity utilized by breeders for crop improvement. This review summarizes status of collections and vulnerabilities for cucurbit crops.
Jim McCreight leads the Melon team. Their objectives are to Map and develop markers for disease resistance in Melon and introgress, pyramid/stack resistances into advanced breeding lines.
The U.S. National Plant Germplasm System maintains a melon germplasm collection from worldwide melon production areas and regions where primitive melons exist. The CucCAP team genetically characterized the collection to increase understanding of genetic diversity, phylogenetic relationships, and population structure of the collection, and to improve melon taxonomic classifications. A core collection was developed from the analysis to provide a public resource for future research and genomics-assisted breeding. Thirty-five morphological characters were evaluated in the core collection to identify genomic regions potentially related to fruit quality and other horticultural traits important in melon improvement.
Resistance to CYSDV is exhibited by melon PI 313970, a vegetable type melon introduced from India.
CucCAP scientist, Rebecca Grumet, will present, “Application of genomic tools for mapping and analysis of valuable traits in cucurbit” at the XIIth Eucarpia Meeting on Cucurbit Genetics and Breeding.
The CucCAP melon team is breeding melons for disease resistance to Powdery mildew, Fusarium wilt, and Cucurbit yellow stunting disorder virus.
