The occurrence of powdery mildew of watermelon has significantly increased in recent years. While the majority of the watermelon varieties evaluated in South Carolina were susceptible to powdery mildew, the seedless variety Suprema and seeded variety Declaration were relatively less susceptible and the commercial pollenizers Lion, SP5 and SP6 were resistant across three years of testing. Because of the frequent […]
CucCAP plant breeder, Todd Wehner talks about breeding cucumber and watermelon varieties for disease resistance.
Watermelon has been domesticated for more than 4000 years and modern sweet watermelons have been selected to carry large fruits with crisp, non-bitter and sweet flesh. The CucCAP team has co-led an international effort to generate an improved watermelon ‘97103’ reference genome and resequence 414 accessions from the seven extant Citrullus species.
The MELCAST and ipmPIPE cucurbit disease forecasting tools have discontinued updates for the 2019 growing season.
SNPS from GBS data of Cucurbita accessions, including C. pepo, C. maxima and C. moschata are made publicly available prior to publication under a data release policy.
With a wide variety of options to choose from, researchers are working with technology in order to grow better cucurbits. Genome-wide association studies (GWAS), marker assisted selection and genomic selection have been used to improve specialty crops like squash, pumpkins and watermelons.
Researchers will focus specifically on vegetable systems and find long-term sustainable solutions to manage whiteflies and whitefly-transmitted virus complexes. There are three whitefly-transmitted viral pathogens, which are known to reduce the quality of vegetable crops, specifically cucurbits: cucurbit leaf crumple virus, cucurbit yellow stunting disorder virus and sida golden mosaic virus.
The McGregor Lab at UGA will collaborate with researchers from three research institutions to use a grant from the USDA to fight whiteflies on vegetable crops. Cecilia McGregor and her lab group will be involved with research on Plant resistant traits and Molecular tools & biotechnology.
