Adult Plant Resistance in Selected Indian Wheat Cultivars and Postulation of Yellow Rust Resistance Genes

Wheat varieties were screened against different pathotypes of Puccinia striiformis for yellow rust resistance both at seedling in optimum temperature under controlled green house as well as adult plant stage under field conditions. By applying the gene matching technique, different combinations of yellow rust resistance genes, viz. Yr 2, Yr9, and Yr18 were characterized. Promising adult plant resistance was observed on the varieties during cropping season 2014 - 15 and 2015 - 16.
