Adaptabilidade e avaliação de progênies de Acca sellowiana (O. Berg) Burret oriundas de melhoramento genético participativo no sul do Brasil

The feijoa is a native species of Southern Brazil and Northeast of Uruguay, with commercial crops and genetic improvement well structured in international scope, specially at New Zealand and Colombia. It has a high potential for cultivation compared to other fruit trees widely cultivated in Brazil....

It has a high potential for cultivation compared to other fruit trees widely cultivated in Brazil. However, despite being well studied, the genetic improvement in Brazil has not yet produced varieties adapted to the different soil and climatic conditions of its area of natural occurrence. The present study aims to evaluate the performance and growth adaptation of seven progenies obtained from crosses between A. sellowiana matrices from a participatory breeding program in eight different locations in southern Brazil, characterizing these segregating populations by identifying superior progenies with better adaptation to the conditions of each place evaluated in relation to the characteristics of survival and initial growth, identifying preferential and marginal places of cultivation for the crossings and plants. The quality of fruits of some progenies in Vacaria - RS was also analyzed in order to highlight promising progenies. The plants were evaluated at 2.5 and 7 years of age, and the height from the ground to the top of the crown (cm), the crown diameter (cm) and the sectional area of the plant neck (mm²) were measured for growth analysis. The data was transformed into annual growth rates to equalize the analyses, in addition to the plant mortality rate at the sites. For the analysis of Vacaria fruits, the fruit diameter (cm), length (cm), total weight (g), pulp yield (%), peel thickness (mm), soluble solids content (°Brix) and total titratable acidity (% citric acid) was measured. It was concluded that there was a GxE interaction for plant growth and mortality. There was better adaptation in general to the Caçador, Ipê, Maquiné and Paraí locations. Dois Vizinhos, David Canabarro, Rio do Sul and Vacaria had lower performance. Likewise, the 1001xHel and 1006xHel plants with greater survival stood out. On the other hand, plants of 1004x1035 and 1051x1035, despite greater growth, had low survival. Therefore, from these results it is not possible to identify an ideal location or progeny, as studies with the fruits are also necessary for the selection of plants in each location, as this is the purpose of their cultivation. Regarding the fruits of Vacaria, the fruits generated by plants three (455) and nine (1001) stand out as promising plants in size, pulp yield and SS content of the fruits, but more studies are needed for an effective selection, as these were the first crops analyzed. A Goiabeira-serrana é uma espécie nativa do Sul do Brasil e Nordeste do Uruguai, com cultivos comerciais e melhoramento genético bem estruturados em âmbito internacional, especialmente na Nova Zelândia e Colômbia. Apresenta elevado potencial de cultivo comparada a fruteiras exóticas comercialmente cultivadas no Brasil, mas apesar dos esforços em pesquisas, o melhoramento genético ainda não produziu variedades adaptadas às diferentes condições edafoclimáticas de sua área de ocorrência natural. O presente trabalho objetivou avaliar em oito diferentes locais da região Sul do Brasil a performance e adaptação de crescimento de sete progênies obtidas a partir de cruzamentos entre matrizes de A. sellowiana provenientes de um programa de melhoramento genético participativo, caracterizando-se essas populações segregantes identificando progênies superiores com melhor adaptação às condições de cada local avaliado em relação às características de sobrevivência e crescimento inicial, identificando-se locais preferenciais e marginais de cultivo para os cruzamentos e plantas. Analisou-se também a qualidade de frutos de algumas progênies em Vacaria – RS com objetivo de destacar progênies promissoras. As plantas foram avaliadas aos 2,5, e 7 anos de idade sendo mensurados para análise de crescimento a altura desde o solo ao topo da copa (cm), o diâmetro de copa (cm)e a área seccional do colo da planta (mm²), dados transformados em taxas de crescimento anuais para equalizar as análises, além da taxa de mortalidade de plantas nos locais. Para análise dos frutos de Vacaria foram mensurados o diâmetro do fruto (cm), comprimento (cm), peso total (g), rendimento de polpa (%), espessura da casca (mm), teor de sólidos solúveis (°Brix) e acidez total titulável (% ácido cítrico). Concluiu-se que houve interação GxA para o crescimento e mortalidade das plantas. Houve melhor adaptação de forma geral aos locais Caçador, Ipê, Maquiné e Paraí. Já Dois Vizinhos, David Canabarro, Rio do Sul e Vacaria obtiveram desempenho inferior. Da mesma forma, destacaramse as plantas de 1001xHel e 1006xHel com maior sobrevivência. Já as plantas de 1004x1035 e 1051x1035, apesar de maior crescimento, obtiveram baixa sobrevivência. Portanto, a partir desses resultados não é possível a identificação de um local ou progênie ideais, pois são necessários estudos com os frutos também para seleção de plantas em cada local, pois esse é o objetivo de seu cultivo. Em relação aos frutos de Vacaria, destacam-se plantas promissoras em tamanho, rendimento de polpa e teor de SS os frutos gerados pelas plantas três (455) e nove (1001). Mais estudos são necessários para uma seleção efetiva, pois essas foram as primeiras safras analisadas. 2022-12-19T21:22:56Z 2022-12-19T21:22:56Z 2022-08-31 masterThesis SOHNE, Ana Elisia.
