Common bean cultivar Mexico 309 presents a wide resistance spectrum to several pathotypes of the fungus Uromyces appendiculatus that occurs in the states of Minas Gerais and Goiás, in Central Brazil. This pathogen is the causal agent of common bean rust. The present study had the following objectives: (i) to determine the inheritance of rust resistance in segregating populations obtained from crosses between cultivars Mexico 309 and Rudá (commercial cultivar susceptible to rust), and (ii) to validate the SCAR marker SI19460 as linked to 'Mexico 309' resistance gene. Results confirmed that 'Mexico 309' has a single dominant rust resistance gene (Ur-5) and that marker SI19460 is linked in coupling phase at 3.31 cM of this gene. This marker can be used for indirect selection of gene Ur-5 during the development of common bean lines resistant to rust using 'Rudá' as one of the progenitors. |

The aimof this study was to develop a diagrammatic scale to evaluate angular leaf spot (ALS) severity in primary leaves of common bean. A diagrammatic scale was developed and validated with nine levels of severity: 0 %; 0.1 to 0.5 %; 0.6 to 4.0 %; 4.1 to 7.0 %; 7.1 to 16 %; 16.1 to 26 %; 26.1 to 32 %; 32.1 to 38 % and 38.1 to 60 %. The use of this scale, associated with the early inoculation method, allowed rating of ALS severity in common bean leaves in the V2 stage of development that is, when the primary leaves are fully open. Validation of the scale was performed by 14 Evaluators. These Evaluators estimated the severity in 40 common bean leaves with different levels of severity, previously measured by the software Quant®. The accuracy and precision of each Evaluator were determined by simple linear regression, by comparing between actual severity, measured electronically, and that estimated by the Evaluator. Without the scale, most of the Evaluators overestimated the severity of the disease. With the scale, the Evaluators obtained better levels of accuracy and precision, with absolute errors less than 5 %. The diagrammatic scale proposed proved to be adequate for early performance of the pathogenicity test. |
