1. Potential of forage and grain yield of maize genotypes in the Brazilian semiarid region
ABSTRACT Maize is importance in the semiarid region due to its forage potential. However, the large number of hybrids on the market hampers the selection of the hybrid by the producer. Given the above, the objective of this paper is to identify genotypes with productive potential for forage and grain production according to the characteristics of the semiari

2. Genome composition and pollen viability of Jatropha (Euphorbiaceae) interspecific hybrids by Genomic In Situ Hybridization (GISH)
Abstract Interspecific hybridization is required for the development of Jatropha curcas L. improved cultivars, due to its narrow genetic basis. The present study aimed to analyze the parental genomic composition of F1 and BC1F1 generations derived from interspecific crosses (J. curcas/J. integerrima and J. curcas/J. multifida) by GISH (Genomic In Situ Hybrid

3. Backcrosses in a segregating population of Passiflora mediated by morphoagronomic and resistance traits
ABSTRACT The present study aims to characterize the genetic diversity of Passiflora setacea, P. edulis, their hybrids, and first-backcross progenies, and to indicate promising recombinants for generation advancement in a breeding program for transferring resistance to cowpea aphid-borne mosaic virus (CABMV). Ninety-one genotypes were evaluated for 37 morphoa

4. Competitive Ability of Canola Hybrids Resistant and Susceptible to Herbicides
RESUMO: Este trabalho objetivou comparar a habilidade competitiva de híbridos de canola, suscetível (convencional) ou com resistência aos herbicidas do grupo das triazinas ou das imidazolinonas, com o nabo. Os experimentos foram conduzidos em casa de vegetação, no delineamento inteiramente casualizado com quatro repetições. Foram utilizados os híbrid

5. Genetic assessment of seed yield-related traits in superior hybrids of Paspalum plicatulum × Paspalum guenoarum
ABSTRACT This study aimed to estimate the genetic parameters, genetic correlations, genetic dissimilarity, and predicted gains with the selection of interspecific apomictic Paspalum plicatulum × Paspalum guenoarum hybrids in relation to seed yield traits. Nineteen genotypes that showed increased forage yield in previous studies were planted in a randomized

6. Selection gains for bunch production in interspecific hybrids between “caiaué” and oil palm
Resumo: O objetivo deste trabalho foi estimar ganhos de seleção para produção de cachos em híbridos obtidos de genitores caiaué (Elaeis oleifera) da população Manicoré e dendê (Elaeis guineensis) da população La Mé, do terceiro ao oitavo ano após o plantio. Avaliaram-se 39 progênies de irmãos completos em experimentos conduzidos em delineamen

7. Evaluation of production and quality traits in interspecific hybrids of ornamental pepper
RESUMO O cultivo de pimentas em vaso como planta ornamental tem aumentado consideravelmente em todo o planeta. No Brasil, esse cultivo é mais recente e ainda carece de cultivares. Para ampliar a variabilidade disponível e obter novas cultivares, a hibridação interespecífica é muito útil como forma de inserir um atributo desejável que ocorre em uma es

8. Biomass association in specimens and interspecific hybrids of tomatoes
ABSTRACT. The objective of this study is to analyze the growth of wild species of tomato, of the cultivar Redenção and of the respective F1 hybrids of interspecific crossings. We evaluated six wild-type accessions (Solanum pimpinellifolium ‘AF 26970’, S. galapagense ‘LA-1401’, S. peruvianum ‘AF 19684’, S. habrochaites var. hirsutum ‘PI-127826

9. Morphological and genetic perspectives of hybridization in two contact zones of closely related species of Petunia (Solanaceae) in southern Brazil
ABSTRACT Interspecific hybridization has several consequences for parental species, from blurring species limits to the emergence of new taxa. Petunia axillaris and P. exserta occur in sympatry in southernmost Brazil and naturally hybridize despite their different pollination syndromes and habitat requirements. We employed genetic and morphological analyses

10. Interspecific Competition Between Sweet Sorghum and Weeds
RESUMO: Enquanto evidências indicam o sorgo sacarino [Sorghum bicolor (L.) Moench] como uma matéria-prima de etanol alternativa durante a entressafra da cana-de-açúcar (Saccharum officinarum L.), pouco se sabe sobre sua capacidade produtiva em condições adversas (sob competição com plantas daninhas, por exemplo). Portanto, o objetivo do presente estu

11. Selection of interspecific Psidium spp. hybrids resistant to Meloidogyne enterolobii
ABSTRACT. Since 2001, the disease known as 'guava decline', resulting from the interaction between the phytonematode Meloidogyne enterolobii and the fungus Fusarium solanie, has caused direct and indirect economic losses to the entire guava production chain. Given the lack of sources of resistance in guava genotypes, interspecific hybrids of Psidium spp. wer

12. A hybrid swarm of manatees along the Guianas coastline, a peculiar environment under the influence of the Amazon River plume
Abstract: The West Indian (Trichechus manatus) and Amazonian (T. inunguis) manatees have a sympatric occurrence at the mouth of the Amazon River. A result of this interspecific encounter is the occurrence of hybrids, which are frequently found along the coasts of Amapá state in Brazil, French Guiana and Guyana. Here we present new genetic evidence indicatin
