In Brazil cultivars have been already developed for high altitude conditions in Santa Catarina state and there is a participatory breeding program of the species in the high altitude region of Rio Grande do Sul state, where the species is adapted to the conditions of that climate. Adaptation of superior genotypes to the southwestern region of Paraná state is unknown, although the species is native to the higher altitude regions of the state. In this context, the objective of this research was to analyze phenological behavior, reproductive biology (pollen germination and autoincompatibility), fruit growth, and yield components of a segregating A. sellowiana population, in order to study the behavior of these species in the region, as well as to select promising genotypes adapted to the region. The experiments were carried out in Dois Vizinhos and Pato Branco, Paraná state from 2014 to 2017, with progenies of five crosses originating from diallel crosses between four elite matrices of the Germoplasma Active Bank of the species: Alcântara, Helena, Mattos e Nonante varieties. The spacing was 4.5 x 3.0m, with experimental arrangement in randomized blocks, containing four replications and each experimental plot being composed of three plants. The evaluated parameters were the phenology of flowering, pollen viability, self-incompatibility, fruit set, fruit growth and productivity. The phenological data were tabulated and presented in graphical form correlated with local meteorological data. The reproductive biology (through manual self-pollination, manual cross-pollination, and open pollination) was also determined, and pollen viability was evaluated by in vitro germination test. In the reproductive phase, productivity, fruit characteristics (size, weight, pulp yield, thickness, soluble solids, color, roughness, and sensory evaluation), maturation and precocity were evaluated. The continuous data collected were submitted to variance analysis and the discrete data to frequency analysis. The cross-pollination at the two study sites showed the greatest increase of fruit set; the progenies that presented the highest number of flowers and fruits were those of the Non x Hel and Alc x Hel crosses. The pollen viability from the two sites was extremely low and atypical for the species. For the fruit growth, cross pollination was the one that presented the greatest length and diameter of fruits. As for phenology, the flowering was advanced by one month at the two sites compared with data from the place where the progenies originated. This set of results aimed to assist the selection of superior genotypes of feijoa, correlated with their adaptability to southwestern Paraná. A Acca sellowiana é espécie frutífera pertencente à família Myrtaceae, nativa do sul do Brasil e do norte do Uruguai, conhecida popularmente no Brasil pelos nomes de goiabeira serrana, araçá-grande, goiabeira-do-mato e feijoa. No Brasil, já foram lançadas cultivares para as condições de altitude de Santa Catarina e há programa de melhoramento participativo na região serrana do Rio Grande do Sul, onde a espécie é adaptada ao clima. Não se conhece a adaptação de genótipos superiores para a região sudoeste do Paraná, embora a espécie seja nativa nas regiões de maior altitude do estado. Neste contexto, este trabalho teve como objetivo analisar o comportamento fenológico, a biologia reprodutiva (germinação de pólen e autoincompatibilidade), crescimento dos frutos e os componentes de rendimento de populações segregantes de feijoa, visando estudar o comportamento desta espécie na região, bem como contribuir para a seleção de genótipos promissores e adaptados. Os experimentos foram instalados em Dois Vizinhos e Pato Branco, no ano de 2011, com progênies de cinco cruzamentos envolvendo quatro matrizes elite do Banco Ativo de Germoplasma da espécie: Alcântara, Helena, Mattos e Nonante. O espaçamento adotado foi 4,5 x 3,0m, com arranjo experimental em blocos ao acaso, contendo quatro repetições, sendo cada parcela experimental composta por três plantas. As variáveis avaliadas foram fenologia de floração, viabilidade do pólen, auto-incompatibilidade, frutificação efetiva, crescimento dos frutos e componentes de rendimento. Para a fenologia da floração, os dados foram tabulados e apresentados na forma gráfica, relacionados com os fenômenos meteorológicos dos locais dos experimentos. A biologia reprodutiva foi estudada mediante autopolinização manual, polinização cruzada manual e polinização aberta, e a viabilidade de pólen avaliada por meio de teste germinativo in vitro. Na fase reprodutiva foi avaliada produtividade, as características de fruto (tamanho, peso, rendimento da polpa, espessura, graus Brix, cor e rugosidade). Os dados contínuos coletados foram submetidos à análise de variância e teste de comparação de médias e os dados discretos à análise de distribuição de frequência. Para os dois locais de estudos a polinização cruzada foi a que mais incrementou a frutificação efetiva. As progênies que apresentaram maior número de flores e frutos foram as do cruzamento Non x Hel e Alc x Hel. Para os dois locais a viabilidade de pólen foi extremamente baixa e atípica para a espécie. A polinização cruzada foi a que apresentou maior comprimento e diâmetro de frutos. Quanto a fenologia, a floração é adiantada em um mês nos dois locais comparandose com os dados de onde as matrizes são oriundas. Esse conjunto de resultados contribui para a seleção de genótipos superiores de feijoa, relacionados com sua adaptação ao sudoeste do Paraná. 2018-05-21T16:08:03Z 2018-05-21T16:08:03Z 2017-08-21 masterThesis TURRA, Eliza Luana Charneski.
