Number of genes controlling slow rusting resistance to leaf rust in five spring wheat cultivars

Summary The number of genes controlling slow rusting resistance to leaf rust (Puccinia triticina) was estimated in five spring wheat (Triticum aestivum) cultivars using quantitative formulae. Parents and F 6 families were evaluated in replicated field trials under epidemics initiated by artificial inoculation. The F 6 families resulted from a diallel cross involving the fast‐rusting cultivar Yecora 70 and five slow‐rusting wheat cultivars:...
