Abstract

ROSA, Daniel Dias; FIRMINO, Ana Carolina  and  FURTADO, Edson Luiz. Chinese cabbage hibrids behavior to Plasmodiophora brassicae isolates. Summa phytopathol. [online]. 2010, vol.36, n.4, pp.342-345. ISSN 0100-5405.  https://doi.org/10.1590/S0100-54052010000400011.

We analyzed the performance of five commercial Chinese cabbage hybrids before the aggressiveness of 24 Plasmodiophora brassicae isolates from different regions of the state of Sao Paulo. The test was conducted in a greenhouse and set out in blocks. It was found that the five hybrids were susceptible to all isolates P.brassicae, and the hybrid 3 with behavior more resistant hybrid and two with the behavior more likely. Among the isolates, it was found that the Piedade-SP isolates were the most aggressive and Ribeirão Preto-SP isolates were less aggressive towards the five hybrids.

Keywords : clubroot of Crucifers; resistance; variability.
