ReferenceSingh RP et al. (2000) Mapping Yr28 and Other Genes for Resistance to Stripe Rust in Wheat Crop Science 40:1148-1155.
Stripe rust resistance genes were mapped in the Synthetic x Opata RI population, using seedling and adult inoculation tests, at three locations in Mexico.
Seedling inoculation tests were performed in the greenhouse at El Batan and adult inoculations in the field at Toluca and Celaya.
