Estudaram-se os efeitos da sulfato de amonio, nitrocalcio, salitre-do-chile, ureia e nitrato de calcio sobre a formacao de galhas em raizes de mudas de cafeeiro inoculadas com Meloidogyne exigua, bem como a influencia desses fertilizantes sobre a taxa de eclosao de larvas do nematoide. A excecao do salitre-do-chile, todos os demais nitrogenados em estudo afetaram o numero de galhas. Houve reducao desse numero com nitrocalcio e sulfato de amonio, e aumento com ureia e nitrato de calcio, quando comparados a testemunha. Dentre os fertilizantes estudados, apenas o nitrocalcio reduziu a taxa de eclosao de larvas de M. exigua. O sulfato de amonio e estimulou e os demais nao alteraram o processo. Muito embora o nitrocalcio e o sulfato de amonio tenham reduzido o numero de galhas, nao se constituem, na dosagem utilizada, numa apreciavel medida de controle de M. exigua, porque o numero medio de galhas, em ambos os tratamentos, foi muito alto. |

In the present work, it was phenotyped 29 Coffea canephora clones for resistance to Hemileia vastatrix races II and XXXIII and investigated the presence of molecular markers associated with Coffee Leaf Rust (CLR) and Coffee Berry Disease (CBD) resistance loci in 67 clones. Phenotyping for resistance was performed by evaluating six components of quantitative resistance using the leaf disc technique. The averages of the components were submitted to the Scott-Knott test and to the multivariate analysis to obtain the generalized Mahalanobis distance, which was used to group the clones by the unweighted pair-group method using arithmetic averages. In screening resistance to CLR, molecular markers were evaluated associated with two resistance loci. Three sequence characterized amplified regions (SCAR) and a simple sequence repeats (SSR) markers associated with the locus of SH3 gene (Locus A); a SCAR and a cleaved amplified polymorphic site (CAPS) associated with a locus of resistance to races I, II and pathotype 001 of H. vastatrix (Locus B). For screening resistance to CBD, two SSRs were associated with the locus of the resistance Ck-1 gene (Locus C) were evaluated. The phenotyped clones were grouped into five resistance classes for each H. vastatrix race. Fifteen clones have locus of resistance to races I, II, and the pathotype 001 of H. vastatrix. Three clones have the Ck-1 gene. These results support growers to choose resistant clones for crop composition and indicate potential sources of CLR and CBD resistance for C. canephora breeding programs.
