Cassava root rot disease is caused by a complex of soil-borne pathogens and has high economic impacts because it directly affects the tuberous roots, which are the main commercial product. This study aimed to evaluate cassava genotypes for resistance to root rot disease in a field with a previous history of high disease incidence. It also aimed to identify possible genomic regions associated with field resistance based on genome-wide association studies. A total of 148 genotypes from Embrapa Mandioca and Fruticultura were evaluated over two years, including improved materials and curated germplasms. Analysis of phenotypic data was conducted, as well as a genomic association analysis, based on the general linear model, mixed linear model, and fixed and random model circulating probability unification. The observed high disease index (ω) was directly correlated with genotype survival, affecting plant height, shoot yield, and fresh root yield. The genotypes were grouped into five clusters, which were classified according to level of root rot resistance (i.e., extremely susceptible, susceptible, moderately susceptible, moderately resistant, and resistant). The 10 genotypes with the best performance in the field were selected as potential progenitors for the development of segregating progenies. Estimates of genomic kinship between these genotypes ranged from -0.183 to 0.671. The genotypes BGM-1171 and BGM-1190 showed the lowest degree of kinship with the other selected sources of resistance. The genotypes BGM-0209, BGM-0398, and BGM-0659 showed negative kinship values with most elite varieties, while BGM-0659 presented negative kinship with all landraces. A genome-wide association analysis detected five significant single nucleotide polymorphisms related to defense mechanisms against biotic and abiotic stresses, with putative association with fresh root yield in soil infested with root rot pathogens. These findings can be utilized to develop molecular selection for root rot resistance in cassava.

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.
