a. Allelism tests of downy mildew resistance loci in cucumber. b. Molecular mapping of downy mildew resistance loci. c. Conduct an outreach program.
a. Allelism tests of downy mildew resistance loci in cucumber: inbred lines carrying multi-source downy mildew resistance genes will be crossed and segregation of resistance will be evaluated in multi-year and location field and greenhouse trials. b. Molecular mapping of downy mildew resistance: Multiple mapped populations will be developed and phenotypic data of downy mildew resistance will be collected. Genomic DNAs of segregation populations and parental lines will be used for molecular marker analysis to identify markers for downy mildew resistance major QTL. c. The outreach program will enhance communication with various segments of the industry, and educate the public on the need for sound scientific practices to resolve biological problems. The outreach target groups will include the cucumber growers, the private seed companies, cucumber scientific community, the youth, and the general public.
