Conteúdo: |
A novel powdery mildew disease was observed on chickpea (Cicer arietinum) in Brazil. The morphological features of fungal colonies and conidia were in agreement with those typical for the genus Leveillula. The total DNA of three field-collected samples were used as template in PCR assays with the pair of primer PMITS1 and PMITS2, targeting the internal transcribed space (ITS) region of Erysiphales isolates. Amplicons were Sanger sequenced and their BLAST analysis revealed 100% identity with a large number of L. taurica (lato sensu, Clade 1) isolates from GenBank. Phylogenetic analysis confirmed the pathogen identification. Equivalent symptoms were observed on chick-pea seedlings after controlled inoculation, fulfilling the Koch's postulates. Leveillula taurica (lato sensu, Clade 1) isolates have been reported infecting Fabaceae hosts worldwide, including chickpeas in North America, Africa and Asia. However, this is the first record of L. taurica infecting this crop in Brazil and South America. |

Conteúdo: |
The objective of this work was to estimate the phenotypic correlation and the direct and indirect effects of the aerial part components of common bean (Phaseolus vulgaris) that are associated with root distribution, in order to facilitate the indirect selection for this character. Sixteen genotypes were used, from which 12 are segregating populations in the F6 generation and four are fixed populations, which were conducted in field conditions in a randomized complete block design, with two replicates. The root system evaluation was performed according to Böhm?s method. Pearson?s phenotypic correlation was estimated by the path analysis. The characters stem diameter, leaf area index, first pod set, and root angle showed the highest positive correlations with root distribution and, therefore, may help the indirect selection for this character. The residual effect was higher than the determination coefficient, which indicates that the independent characteristics do not have a total influence on root distribution, and the low values of the determination coefficients can be attributed to environmental effects, competition for nutrients, and to different physiological mechanisms that control the expression of several genes with minor effects. |
