Behavior of different potato genotypes against early blight(Alternaria solani) (Sor.) in seedbed conditions
Journal Title: Biotecnología Vegetal - Year 2004, Vol 4, Issue 1
Abstract
The behavior of variantees IBP-10, IBP-27, the varieties ‘Diacol capiro’, ‘Desirée’ and Solanum chacoense species was evaluated in seedbed in front of Early blight diseases. Artificial inoculation with micelial homogenized of CCIBP-As 4 isolated obtained at the Phytopathology laboratory from the Instituto de Biotecnología de las Plantas. The number and weight of tubers was also evaluated in the studied genotypes. It was observed differential behavior in the intensity of the affectations caused by the disease in the evaluated genotypes. An increase in the intensity of the affectations from 50 days the plants had sprouted was observed. It was realized that the ‘Diacol capiro’ variety presented greater number of tubers but their weight was lower. The IBP-10 reached superior values in both variables with respect to the variety ‘Desirée’.
