Methods for Screening Wheat Genotypes for Resistance to Sharp Eyespot in the Field and Greenhouse

Screening methodology of wheat genotypes for resistance to sharp eyespot (caused by Rhizoctonia cerealis) was developed. Disease severity differed among cultivars and between field and greenhouse trials. However, the cultivars Bobtail and Rosalyn had consistently lower severity in field experiments...

520 |a Screening methodology of wheat genotypes for resistance to sharp eyespot (caused by Rhizoctonia cerealis) was developed. Disease severity differed among cultivars and between field and greenhouse trials. However, the cultivars Bobtail and Rosalyn had consistently lower severity in field experiments with high sharp eyespot disease pressure. Artificial inoculation was crucial to achieving adequate disease levels for effective screening but planting date had very little effect. Greenhouse inoculation of adult wheat plants was much less successful in categorizing resistance to sharp eyespot. Seedling inoculations in the greenhouse were highly inadequate as a screening method. Selection for resistance to sharp eyespot by artificial inoculation in field trials is feasible in wheat breeding programs
