RESUMO:

Tectona grandis, popularly known as teak, is an economically important tree species in the timber sector in Brazil. The market is interested in the attractive characteristics of wood such as beauty, color, durability, physical aspects and flexibility of use. Its use is mainly intended for the furniture industry, but other important sectors are covered such as shipbuilding, floors and decoration utensils. The adaptability of teak to soils and tropical climates is another aspect that makes it possible to maximize commercial plantations. One of the factors that limit production is the occurrence of diseases, including canker caused by L. theobromae, which is one of the most destructive, as it infects the stem and directly compromises the quality of the wood. Therefore, this work will be developed with the objective of identifying teak resistant genotypes to canker, through phenotyping studies of clones inoculated with L. theobromae. A fungus isolate will be inoculated into 187 teak genotypes, in a randomized block design (DBC) with three replications and experimental unit consisting of 2 plants per plot. The inoculation of the seedlings will follow the methodology proposed by the consulted literature, with adaptations, 120 days after transplanting the seedlings. The seedlings will be slaughtered in a destructive way in order to evaluate and measure the area colonized by the pathogen with photographic record and evaluation made through image software 120 days after inoculation. Finally, analysis of variance will be performed and the averages will be grouped by Scott knott. Based on the results obtained, promising clones will be indicated for the next stages of improvement, contributing to the creation of resistant cultivars, collaborating with teak foresters and the country's forestry development.
