Phenotyping selected Australian wheat genotypes for resistance to stem rust and yellow rust and yield performance in Kenya

June 2022

Stem rust and yellow rust are major diseases of wheat (Triticum aestivum L.) caused by Puccinia graminis and Puccinia striiformis, respectively. In Kenya, although the two diseases occur together, available genetic resistance is limited. Therefore, research for resistance to both diseases is of priority. We therefore evaluated 59 Australian wheat genotypes alongside local checks over three seasons in Njoro, Kenya, for...
