Search for partial resistance against Puccinia hordei in barley landraces from the Fertile Crescent

A collection of 111 barley landraces from the Fertile Crescent was screened for resistance to barley leaf rust in the field and under controlled conditions. Large variation was observed for disease severity under field conditions. Accessions with high resistance because of hypersensitivity were iden...
