The objective of this work was to evaluate the yield performance of two generations (BC2F2 and BC2F9) of introgression lines developed from the interspecific cross between Oryza sativa and O. glumaepatula, and to identify the SSR markers associated to yield. The wild accession RS‑16 (O. glumaepatula) was used as donor parent in the backcross with the high yielding cultivar Cica‑8 (O. sativa). A set of 114 BC2F1 introgression lines was genotyped with 141 polymorphic SSR loci distributed across the whole rice genome. Molecular analysis showed that in average 22% of the O. glumaepatula genome was introgressed into BC2F1 generation. Nine BC2F9 introgression lines had a significantly higher yield than the genitor Cica‑8, thus showing a positive genome interaction among cultivated rice and the wild O. glumaepatula. Seven QTL were identified in the overall BC2F2, with one marker interval (4879‑EST20) of great effect on yield. The alleles with positive effect on yield came from the cultivated parent Cica‑8. |

Persimmon fruit (Diospyros kaki L.) from commercial orchards located in southern Brazil, in Curitiba, Paraná, showed dark firm rot. The incidence in the field was about 2% in an evaluation in the 2016 growing season, and from these infected fruit, three Phytophthora sp. isolates were obtained. Therefore, this study aimed to identify the causal agent of the disease through morphophysiological and molecular analysis of the isolates. Initially, the pathogenicity test was performed on persimmon fruit to fulfil Koch's postulates. Mycelial growth at eight temperatures ranging from 8°C to 35°C was evaluated for taxonomic purposes. Next, the morphological characteristics of sporangia, chlamydospores and oospores were evaluated. For molecular characterization, sequencing of the ITS-rDNA region and portions of the COXI and TEF1? genes and phylogenetic analysis were performed. All isolates were pathogenic, causing symptoms of firm and dark rot similar to those observed in the orchards. Mycelial growth was not observed at 35°C. There was an abundant production of ellipsoid, papillate, deciduous sporangia with long pedicels and the formation of globose chlamydospores. The isolates were heterothallic, all belonging to group A1, in which the production of plerotic oospores with amphigenous antheridia was verified. The morphophysiological and molecular characterization allowed the identification of the isolates as Phytophthora tropicalis. To our knowledge, this is the first report of persimmon fruit rot caused by P. tropicalis.
