Evaluation location: Arkansas, United States
Germination rate under Pythium inoculation (P. aphanidermatum Yuma isolate) and normal condition
in 176 spinach accessions. Two reps of germination rate under Pythium inoculation as a percent of two reps of germination rate in normal conditions. RDI (relative disease index) (100* germination rate under disease stress / germination rate control). The 'Viroflay' check variety RDI = 8.84. Data provided by Ainong Shi, University of Arkansas, in 2023. Shi, A., J. Correll, and Gehendra Bhattarai, “Evaluation and Association Analysis of resistance to Pythium on USDA Spinach Germplasm” from USDA Germplasm Evaluation grant 58-5030-0-047, 08/01/2020 – 08/31/2022, a total of $24,500.
