ABSTRACT - The objective of this work was to determine the genetic diversity, yield, and fruit quality of persimmon genotypes grown in the tropics, in order to select promising genetic materials. DNA extraction was performed on young leaves of 19 persimmon genotypes. For pomological characterization, 15 genotypes were selected. From each genotype, 50 fruit at the physiological maturity stage were harvested in the morning, in order to determine the following parameters: physicochemical characteristics; and the productive variables number of fruit per plant, average fruit fresh mass, average yield, and estimated average yield in two seasons. Twenty SSR markers were tested, out of which 12 were selected to evaluate genetic similarity, which allowed of the identification of distinct groups. The mean genetic diversity value found was 0.41, which is an indicative of low diversity among the analyzed persimmon genotypes. The 'Guiombo', 'Iapar 125', 'Kakimel', 'Mikado RJ', 'Rama Forte Tardio', and 'Taubaté' genotypes show a high yield. The genotypes classified as pollination-constant astringent ('Pomelo', 'Regina', 'Rubi', and 'Taubaté') and those classified as pollination-variant astringent ('Rama Forte', 'Guiombo', and 'Cereja') are potential materials for selection and genetic breeding programs due to their excellent fruit physicochemical characteristics. The investigation through molecular markers is an efficient approach to study the genetic diversity of persimmon genotypes grown in the tropics. RESUMO - O objetivo deste trabalho foi estimar a diversidade genética, o rendimento e a qualidade de frutos de genótipos de caquizeiros cultivados nos trópicos, para selecionar materiais genéticos promissores. A extração de DNA foi realizada em folhas jovens de 19 genótipos de caqui. Para a caracterização pomológica, foram selecionados 15 genótipos. Para cada genótipo, 50 frutos foram colhidos pela manhã, no estágio de maturidade fisiológica, para determinar os seguintes parâmetros: características físico-químicas; e as variáveis produtivas número de frutos por planta, massa de matéria fresca média dos frutos, produtividade média e produtividade média estimada, em duas safras. Vinte marcadores SSR foram testados, dos quais 12 foram selecionados para avaliar a similaridade genética, o que permitiu a identificação de grupos distintos. O valor médio de diversidade genética encontrado foi 0,41, o que é indicativo de baixa diversidade entre os genótipos de caqui analisados. Os genótipos 'Guiombo', 'Iapar 125', 'Kakimel', 'Mikado RJ', 'Rama Forte Tardio' e 'Taubaté' apresentam alta produtividade. Os genótipos classificados como sendo de polinização constante adstringente ('Pomelo', 'Regina', 'Rubi' e 'Taubaté') e os classificados como sendo de polinização variante adstringente ('Rama Forte', 'Guiombo' e 'Cereja') são materiais com potencial para uso em programas de seleção e melhoramento genético, devido às suas excelentes características físico-químicas de fruta. A investigação por meio de marcadores moleculares é uma abordagem eficiente para estudar a diversidade genética de genótipos de caquizeiro cultivados nos trópicos.

Intensive melon cultivation is based on conventional monoculture models that can inefficiently use natural resources, which, combined with inadequate management, contribute to climate change. The main objective of this study was to model the future carbon stock in melon cultivation agroecosystems under different climate scenarios. The study was conducted at the Bebedouro Experimental Field of Embrapa Semi-arid, Petrolina/PE, Brazil, in an area cultivated with yellow melon cv. Gladial, and eight cultivation cycles were considered. The experimental design was composed of two types of oil management (with and without tillage), two treatments using green manures consisting of 14 species with different proportions of legumes, grasses and oilseeds, and spontaneous vegetation, containing four replications divided into randomized blocks. After 70 days of development, the plants were cut and placed in the soil. Temperature and precipitation data were acquired from the BCC- CSM, MIROC5, CESM1-BGC, IPSL-CM5B-LR, and HadGEM2-AO climate models, following the RCP 4.5 and 8.5 climate scenarios. The carbon (C) stock was estimated until the year 2071 using the RothC model. The treatment with a predominance of legumes and no rotation increased the C stock in the soil, regardless of the climate scenario. The soil tillage did not favor C accumulation, meaning that none of the treatments reached the same stock as the Caatinga. The MIROC5 model in the RCP 4.5 scenario favored greater C accumulation in the soil, while the lowest C stocks occurred in the CESM1-BGC and IPSL-CM5B-LR models under the RCP 8.5 scenario.
