Última Evaluation of genetic mixtures of sorghum lines for anthracnose resistance management Trop. Plant Pathol. Costa,Rodrigo V. da; Casela,Carlos R; Zambolim,Laércio; Santos,Fredolino G; Vale,Francisco X. R. do. The main objective of this work was to evaluate the diversification of sorghum (Sorghum bicolor) populations as a way to manage resistance to the sorghum anthracnose fungus Colletotrichum graminicola. A total of 18 three-way hybrids were obtained by crossing six single cross male-sterile F1 hybrids, derived by crossing A (non restorer sterile cytoplasm) and B (non restorer normal cytoplasm) lines, with three fertile R (restorer) lines, previously evaluated for their differential reaction to the pathogen. Variation in the level of resistance was observed, as indicated by the values of the area under the disease progress curve (AUDPC) obtained for each hybrid. Lines contributed differently to the level of resistance of each hybrid. All hybrids in which... Tipo: Info:eu-repo/semantics/other Palavras-chave: Colletotrichum graminicola; Resistance management.

Barbosa,Flavia C. R; Casela,Carlos R; Pfenning,Ludwig H; Santos,Fredolino G. The main objective of this work was to identify sources of resistance in sorghum (Sorghum bicolor) to Peronosclerospora sorghi, the causal agent of downy mildew, through the evaluation of 42 sorghum genotypes under natural infection in the field. Genotypes were planted in single row plots between two rows of the susceptible line SC283, planted 30 days before, to act as spreader rows, in two separate nurseries. The experimental design was a completely randomized block design with three replications. Sorghum genotypes CMSXS156, CMSXS157, CMSXS243, TxARG-1, 8902, 9902054, 9910032, 9910296, Tx430, QL-3, SC170-6-17, CMSXS762 and BR304 were classified as highly resistant in both nurseries. Among these, SC170-6-17 and 9910296 showed 0% systemic infection. Results... Tipo: Info:eu-repo/semantics/other Palavras-chave: Sorghum bicolor; Diseases; Genetic; Resistance; Downy mildew.
