I am identifying which of Michael Mazourek’s Cucurbita moschata and C. maxima breeding lines are: 1) resistant to powdery mildew and 2) candidate replacements for the susceptible cultivars used in the processing industry.
CucCAP researchers and stakeholders met on October 27, 28 & 29, 2022 to present and discuss the grant’s accomplishments, ongoing research, plans and expectations. Lina Quesada-Ocampo (NC State University), Mary Hausbeck (Michigan State University), Chris Smart (Cornell University), Anthony Keinath (Clemson University), Shaker Kousik (USDA-ARS), Jonathan Schultheis (NC State University), Daniel Tregeagle (NC State University), and Mary Lorscheider (NC State University Extension communicator) reported on the Integrated Disease Management Team’s progress.
This pHD candidate’s CucCAP grant research focused on developing squash breeding lines with some Phytophthora blight resistance and mapping genes involved in disease resistance. His other focus was pathogen population genetics. In CucCAP1 the squash team sequenced and characterized isolates of the causal agent, Phytophthora capsici, from around New York and mapped genes in the pathogen associated with mating type, fungicide resistance, and virulence.
CucCAP researchers and stakeholders met on October 27, 28 & 29, 2022 to present and discuss the grant’s accomplishments, ongoing research, plans and expectations. Michael Mazourek (Cornell Univ), Mary Hausbeck (Michigan St Univ), Shaker Kousik (USDA-ARS, Charleston), Geoffrey Meru (Univ Florida), Angela Linares Ramirez (Univ Puerto Rico), and Chris Smart (Cornell Univ.) reported on the Squash Team’s progress.
In this study, researchers at Cornell collected 252 strains of the pathogen from across New York State and sequenced portions of their DNA in order to characterize the genetic structure of the pathogen population.
The CucCAP squash team is breeding squash for Powdery Mildew and Phytophthora rot resistance.
CucCAP scientists from the Cornell University research groups of Michael Mazourek and Christine Smart along with Michael Gore’s lab combined linkage mapping and bulked segregant methods for molecular mapping and QTL identification.
Researchers at Cornell University developed squash breeding lines with increased resistance to Phytophthora crown and root rot.
