The Cucurbit Genetics Cooperative (CGC) was established in 1977 to develop and advance the genetics of economically important cucurbits. CucCAP Team members have contributed many articles to the Cucurbit Genetics Cooperative throughout the years. Members of the CucCAP Team contributing to CGC report#41 for 2018 include authors Todd Wehner and Jim McCreight along with editors, Amnon Levi and Linda Wessel-Beaver.
Wehner Lab @ NC State
Todd C. Wehner led the Cucurbit Breeding Lab at NC State University and was a member of the Cucumber and Watermelon teams during the first CucCAP grant; Luis Rivera-Burgos, (aka. Luchinski Rivera) was a post doctoral candidate in the lab in 2016 and 2017 working on Breeding Watermelon for Gummy Stem Blight Resistance. Emily Silvermen was a Graduate Research Assistant in the Wehner Lab.
Wehner Appointed Williams Neal Reynolds Distinguished Professor | NC State
Dr. Todd C. Wehner is William Neal Reynolds Distinguished Professor and leader of the cucumber and watermelon breeding project at North Carolina State University.
Watermelon Team | 2019 CucCAP Progress Report
Watermelon Team members: Amnon Levi (USDA, ARS), Shaker Kousik (USDA, ARS), Kai-shu Ling (USDA, ARS), Cecilia McGregor (Univ. Georgia), Pat Wechter (USDA, ARS), Todd Wehner (North Carolina St. Univ.)
Overall objectives: Identifying quantitative trait loci (QTL) associated with resistance to major and emerging diseases, developing useful molecular markers and utilizing the genomic tools to incorporate resistance into watermelon cultivars.
Major diseases: Gummy stem blight, Fusarium wilt, Powdery mildew, Phytophthora fruit rot, Papaya ringspot virus (PRSV) and Cucumber green motile mosaic virus (CGMMV).
Cucumber Team | 2019 CucCAP Progress Report
Team members: Yiqun Weng (USDA, ARS), Rebecca Grumet (Michigan St. Univ.), Todd Wehner (North Carolina St. Univ.) report on GBS of PI lines and GWAS panel selection, Phenotyping of morphological traits and DM resistance in cucumber natural populations, QTL mapping, marker development for DM and PFR resistances, Phytophthora capsici fruit rot resistance in cucumber, Young fruit resistance to P. capsici, Age-related resistance (ARR) to P. capsici, Defense response in ARR+ fruit., QTL mapping of ARR., Advanced line development for downy mildew resistance, Breeding line development for DM resistance, and RIL development and evaluation of DM resistance in 2018 & 2019.
CucCAP Researchers Provide High Resolution Genetic Characterization of the U.S. Cucumber Germplasm Collection
High-throughput, high resolution, genetic characterization of the complete cucumber germplasm collection. maintained by the US National Plant Germplasm System was performed by genotyping by sequencing.
CucCAP at Cucurbitaceae 2018
Cucurbitaceae is an international conference of cucurbit scientists held every four years in North America. Cucurbitaceae 2018 was hosted by UC Davis in Davis, California. CucCAP was well represented with 14 Co-PIs and 28 lab members in attendance presenting five invited keynote talks, an additional 12 invited talks, and 19 posters.
CucCAP research identifies a cucumber gene for resistances to downy mildew, angular leaf spot and anthracnose
Development of varieties with multiple disease resistances is always an important goal for plant breeders. Dr. Yiqun Weng’s Lab at the Vegetable Crops Research Unit in USDA-ARS, Madison, Wisconsin identified the STAYGREEN gene that is responsible for the PI 197087-derived triple-disease resistances.
CucCAP team presentations at Cucurbitaceae 2018
CucCAP plant breeders, pathologists and genomic scientists will present results of their work with cucurbit breeding lines and disease resistance at Cucurbitaceae 2018. On Wednesday, November 14, Rebecca Grumet will be the keynote speaker in the first genomics session with the presentation, The CucCAP Project: Genomic Tools and Resources to Facilitate Breeding for Disease Resistance […]
