| Abstract Oryza sativa, the common cultivated rice, is one of the most important crops for human consumption, but production is increasingly threatened by abiotic stresses. Although many efforts have resulted in breeding rice cultivars that are relatively tolerant to their local environments, climate changes and population increase are expected to soon call for new, fast generation of stress tolerant rice germplasm, and current within-species rice diversity might not be enough to overcome such needs. The Oryza genus contains other 23 wild species, with only Oryza glaberrima being also domesticated. Rice domestication was performed with a narrow genetic diversity, and the other Oryza species are a virtually untapped genetic resource for rice stress tolerance... |

| Abstract This research aimed to evaluate techniques for in vitro multiplication and rooting and ex vitro adaptation of wild blackberry plants (Rubus bogotensis Benth. and Rubus macrocarpus Kunth). In in vitro phases, the influence of culture media was evaluated based on Murashige & Skoog (MS) composition, with or without a 50% reduction in salts, vitamins, and myo-inositol and supplemented or not with benzylaminopurine (BAP), indole acetic acid (IAA), L-cysteine, agar, peat, perlite, and vermiculite. The ex vitro phase was based on a soil, rice husks, peat, and perlite substrate management. After two months of evaluation of the in vitro phases, it was determined that the MS medium at 50% salts, vitamins, and myo-inositol and supplemented with sucrose... |

| ABSTRACT The eggplant is a highly valuable horticultural crop grown all over the world and it is of substantial economic importance in Asia. However, its production is severely threatened by several soil-borne and foliar diseases, insect-pests, drought, heat, and frost damage. Therefore, efforts to transfer useful resistance genes into eggplant from their wild relatives is important. In the present study, interspecific and intraspecific hybridization was carried out, that included three cultivated genotypes of eggplant (Solanum melongena MEE, Solanum melongena MEP, Solanum melongena MEB) and one wild Solanum species (Solanum incanum INC). The F1 hybrids were made by inter and intraspecific hybridization. A total of 632 possible inter and intraspecific... |
