CucCAP scientists and collaborators provide an extensive review of the literature to systematically document genes for simply inherited traits, QTL for 130 quantitative traits, and develop recommendations for QTL nomenclature in cucumber. In a separate study, researchers conducted comparative analysis on the genetic basis of fruit size and shape variation among cucumber, melon and watermelon, and revealed both conserved and unique genetic architecture of fruit size/shape variation among cucurbit crops.
PAG brings together over 3,000 leading genetic scientists and researchers in plant and animal research, and over 130 exhibits, 150 workshops, 1100 posters and over 1800 abstracts.
CucCAP participants at PAG XXVIII include cucurbit breeders and genomic scientists. The cucurbit session organizers are Amnon Levi and Patrick Wechter. Presenters include Zhangjun Fei, Rebecca Grumet, Ben N. Mansfeld, Yiqun Weng, Sandra E. Branham, Shaker Kousik, Amnon Levi, and Patrick Wechter, and Umesh Reddy.

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.
The CucCAP team, in collaboration with scientists from around the world, has developed the Cucurbit Genomics Database (CuGenDB), which provides a central portal for the research and breeding community to store, mine, analyze, integrate and disseminate rapidly accumulated genomic and genetic data in cucurbits.
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.
The Plant & Animal Genome Conference (PAG) is designed to provide a forum on recent developments and future plans for plant & animal genome projects. Consisting of technical presentations, poster sessions, exhibits and workshops, the conference is an excellent opportunity to exchange ideas and applications on this internationally important project.
