RESUMO:

Ramularia leaf spot is one of the diseases that affect cotton in Brazil. The disease is widely spread in cotton producing region in Brazil. The aim of this study is to identify critical point on the leaf of cotton in which disease develops by the use of different microscopy.

The comparative histopathological characterization is among the study carried out in the evaluation of the disease resistant cultivars. It help in understanding the plant pathogen intraction, detect critical point for the pathogenesis, pathogen’s infectious process, plant defense responses and component of structural or constitutive defense of the plant. Several tools can be used for selection of line in genetic improve program from techniques that require less resources to those that require very expensive reagents and equipment, to more sophisticated techniques.

Three cotton cultivars with different levels of resistance to two isolates ofRLS( FICC and F3) will be used in this study to determine the level of susceptibility and resistant.Microscopy techniques will be use (LM, SEM, TEM and LCM) to characterize the interaction of Ramulariopsispseudoglycineswith leaf tissues of cotton genotypes with different levels of resistance to RLS. Using completely randomized block design, a total of 60 plastic pots will be required to grow three cotton cultivars. Thirty (30) plastic pots of cotton seed containing three cultivars will be used for severity. The other 30 will be used to determine the effect using microscopy in the laboratory.
