Five spring wheat cultivars differing in partial resistance (PR) to wheat leaf rust were tested at Wageningen (the Netherlands) on a sandy and a clay site, El Batan (CIMMYT, Mexico) and Ponta Grossa (Brazil) over two years . The cultivars were Skalavatis 56, Little Club (both very susceptible), West

Three components of partial resistance (PR) were studied at three post-infection temperatures using seven spring wheat genotypes differing in level of PR and two different wheat leaf rust races . The components were latency period (LP), infection frequency (IF) and urediosorus size (US) . The expres
Latency period (LP), infection frequency (IF) and urediosorus size (US) of leaf rust were determined on primary leaves and young flag leaves of 18 spring wheat cultivars . A large growth stage effect and a large cultivar effect on all three components were observed . Partial resistance as measured b
