| The objective of this work was to identify genomic regions that underlie resistance to Fusarium tucumaniae sp. nov., the causing agent of sudden death syndrome (SDS) in soybean in South America, using a population with a genetic background different from that previously reported for Fusarium virguliforme sp. nov. (F. solani f. sp. glycines), also responsible for SDS in soybean. Although major genes and quantitative trait loci (QTL) for SDS resistance have been identified, little is known about the same disease caused by Fusarium tucumaniae sp. nov., in South America. To identify genetic factors related to resistance to F. tucumaniae and DNA markers associated with them, a QTL analysis was performed using recombinant inbred lines. The map locations of the... |

| Abstract: The objective of this work was to assess the effect of sowing date on the intensity of wheat blast disease, as well as the yield losses caused by this disease in different wheat (Triticum aestivum) genotypes. The experiments were conducted in 2013 at the Sertãozinho experimental station of Empresa de Pesquisa Agropecuária de Minas Gerais (Epamig), in the municipality of Patos de Minas, in the state of Minas Gerais, Brazil. Fourteen wheat genotypes and two sowing dates were evaluated. The experimental design was a randomized complete block with three replicates. The evaluated variables were: incidence, severity, thousand grain weight (TGW), grain yield, and yield losses. A disease index (DI) was calculated, based both on the incidence and the... |

| Charcoal rot, caused by Macrophomina phaseolina (Tassi) Goid., is an economically important disease of oilseed plants in Northern Iran. Seventy isolates of M. phaseolina were obtained from different hosts, including soybean (Glycine max L.), and sunflower (Helianthus annuus L.) in the northern oilseed planting regions of Iran. RAPD-PCR amplification profiles, by using of six random OPA primers (kit A) showed polymorphisms among the isolates. The primer OPA-13 (5'_ CAGCACCCAC_3') amplified the genomic DNA of all isolates of M.phaseolina producing 4-12 bands of sizes between 0.25 and 2.3 kb. Unweighted pair-group method with arithmetic mean (UPGMA) analysis classified the isolates into the nine major groups with 64% similarity. Pathogenicity of isolates was... |
