Chickpea rust (Uromyces ciceris-arietini (Grognot) Jacz. & Boyd.) is an important foliar disease in all areas where this legume is cultivated. The present work was carried out during two consecutive years (2009 and 2010), with the objective of evaluating, under field conditions, the incidence (I) and severity (S) of chickpea rust on 28 genotypes and its relationship with leaf types (TH) uni-imparipinnate (A) and multipinnate (B). In the time studied, rust manifested massively late, with I = 92.14 % and S = 61.10 %, corresponding the highest infection levels to genotypes with leaf type A, compared to leaf type B; three lines B and one A presented better behavior to rust. Severity and incidence was correlated with each other and with the TH. This work constitutes the first study carried out in Cuba about genotypes response to rust and represents an advance step in the genetic improvement related with the selection, adoption and dissemination of chickpea cultivars with a better disease behavior.
