Abstract
A collection consisting of 140 accessions of chickpea (Cicer arietinum L.) and 109 accessions of related wild species (Cicer spp.) was screened for resistance to chickpea rust (Uromyces ciceris-arietini (Grognot) Jacz. & Boyd). Varying levels of partial resistance were identified, based on a reduced disease severity and area under disease progress curve without any macroscopically visible host cell necrosis. Higher levels of resistance were observed in wild Cicer species, but neither associated with hypersensitivity. Components of resistance have been macros- and microscopically studied in selected C. arietinum accessions. Resistance was expressed as longer latent period and lower infection frequency, which were associated with increased percentage of early aborted colonies, reduced number of haustorial mother cells and haustoria per colony, and reduced colony size.

| Additional Information: | Authors are greatly indebted to projects RTA01-130 and AGL2011-22524 for financial support and to A. Moral, A. Molina and R. Cantarero for technical assistance. This study was inspirited in the memorial of Manuel Rubiales, a subsistence farmer that during the difficult times after Spanish Civil Word (around 1940) lost his chickpea crop in the hills of Silla del Caballo, at Ubrique, southern Spain due a to ‘‘mildew that put your trousers red-brown’’. This vague and imprecise oral reference of the reasons of the famine to his child nephew inspired the interest on this little studied disease. |
