2020 Watermelon Field Evaluations

 We just finished our watermelon field evaluation for summer 2020. Due to Covid we did not have as many field plots as usual, at least we got something out of this season. Thanks for everybody's help with planting, trailing and harvesting.

At last - Field plots 2020!

Due to covid all our field trials were delayed and we scaled down our summer field plots significantly. But al last we were able to transplant some watermelon this week! As you can see we are all staying safe in the field!

Winnie Gimode (PhD student) is very excited that this will be her last watermelon field transplanting. She will be graduating in August.

And here is Sammy Josiah (PhD student) planting his first field experiment.

PostDoctoral Position available

The Vegetable Breeding, Genetics and Genomics lab searches for an energetic and creative postdoc. The applicant will participate in cucurbit breeding and genetics for resistance to whitefly and whitefly transmitted diseases as part of a team in the southeastern USA. The applicant will work on identifying sources of resistance, resistance loci and genes, doing functional analysis of genes, and introgression of resistance into elite material. The candidate will work in collaboration with molecular biologists, plant pathologists, entomologists and extension faculty.

The position will start on 1 Oct 2019, but a later start is negotiable. We provide competitive salary, and benefits. Screening of applicants will begin immediately and applications will be considered until position is filled. Interested parties should submit their application at UGA Jobs (https://www.ugajobsearch.com/postings/106233), including a curriculum vitae (CV), a cover letter, statement of how your research interests are related to the interests of the lab, and contact information for 3 references.

UPDATE: This position has been filled.

Mathew Li Wins First Place in Young Scholar Oral Presentation Competition!


Over this summer our lab had the pleasure of hosting Stevenson High School student Mathew Li through the UGA CAES Young Scholar program. Mathew worked with one of our graduate students on determining the sporulation rates of various isolates of Stagonosporopsis fungi so that they can be used for phenotyping watermelon lines for resistance to gummy stem blight. Mathew’s work helped to identify 8 isolates with sufficient spore production for making GSB inoculum, as well as determining which species of Stagonosporopsis each of the isolates belonged to. Mathew took first place in the Athens division of the Young Scholar oral presentation competition, continuing the McGregor lab's tradition of victory in the Young Scholar program. We look forward to seeing great things from Matt and hope that he chooses UGA to continue his educational journey.

Derrick Ousley - REEU fellow

This summer our lab hosted Derrick Ousley as part of the Crop Genetic and Genomics REEU program. Jorge Reyes mentored Derrick in his research project. Today Derrick presented his poster  entitled "Developing Recombinase Polymerase Amplification (RPA) Assays for Gummy Stem Blight Pathogen Detection in Watermelon" at the REU/REEU Summer Research Poster Forum. It was a pleasure having Derrick with us this summer and we wish him all the best as he continues his undergraduate education.
