CucCAP Cucumber Team
CucCAP Cucumber Team contributions include annual reports of research activities, publications and presentations, and articles about the team’s research efforts and accomplishments.
CucCAP scientists uncover the genetic basis of unique horticultural traits in the multi-disease resistant cucumber germplasm line WI2757
CucCAP researchers conducted molecular mapping using populations involving WI2757, and uncovered a large paracentric inversion of about 10 megabases in length on cucumber chromosome 1 of WI2757 and found that inversion region harbors genes or quantitative trait loci for fruit length, diameter, fruit shape, fruit number, and flowering time.
CucCAP #1 Cucumber Research Publications
CucCAP scientists provide inventory of genes and QTL for cucumber breeding and genetics community
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.
