A cultura da manga (Mangifera indica L.) possui grande importância social e econômica no Brasil. Entretanto,os cultivos comerciais são baseados apenas nas cultivares Tommy Atkins e Palmer, sendo necessário o aumento dabase genética por meio da disponibilidade de novas cultivares superiores. Neste trabalho, objetivou-se verificar avariabilidade genética molecular de 15 cultivares e híbridos elite de manga avaliados no Ensaio Nacional deCultivares, utilizando marcadores moleculares RAPD e ISSR. O DNA genômico das 15 plantas foi extraído e amplificadovia Reação em Cadeia Polimerase, utilizando-se 10 primers para RAPD e 7 para ISSR. Foram obtidos 150 marcadoresRAPD e 135 marcadores ISSR, os quais foram codificados em dados binários. Foi calculada uma matriz de dissimilaridadegenética, a partir da qual foram realizadas as análises de agrupamento e dispersão gráfica. Pela análise de agrupamentoe dispersão gráfica foi possível observar a variabilidade genética entre os materiais. A cultivar ?Rosa 2? e o ?híbrido263/99? foram os que apresentaram maior dissimilaridade genética, sendo alternativas para ampliar a base genética dasatuais cultivares de manga utilizadas pelos fruticultores. Os marcadores moleculares RAPD e ISSR foram úteis ecomplementares para o estudo da variabilidade genética das cultivares e híbridos de manga. |

The objective of this study was to analyze the relationship between aspects related to financial management and The objective of this study was to analyze the relationship between aspects related to financial management and scale of production with quality traits (total bacteria count - TBC; somatic cell count - SCC) and composition (protein, fat, lactose, total solids, and non-fat solids) of refrigerated bulk tank milk from 100 dairy farmers located in the south of Minas Gerais state, Brazil, by application of a semi-structured questionnaire. Dairy farmers were categorized according to the daily milk production: small (lower than 150 L); medium (151 to 500 L); and large (higher than 501 L). Chi-square tests and identification of possible relative risks between financial aspects and current regulation standards (Normative Instruction No. 62 of December 29, 2011, Ministry of Agriculture, Livestock and Supply) associated to TBC (higher 300,000 CFU/mL) and SCC (higher than 500,000 cells/mL) means from bulk tank milk among different milk scales productions were performed. Bulk tanks milk composition met the legislation standards and had not differ between scales of production; however, SCC means within all scales, and TBC of small farmers had not attended the legislation standards and differences were identified (P < 0.05). Regarding the financial management aspects, most farmers had no control over incomes, costs, nor calculated milk production cost, with decreased incidences as scale of production increased. Chi-square tests identified that producers that had no concern about milk quality payment bonuses had TBC means 2.95 times more likely (P < 0.05) to be above the current regulations. Small dairy farmers had a greater negligence of the costs management and hygienic milk production as compared to medium and large farmers. scale of production with quality traits (total bacteria count - TBC; somatic cell count - SCC) and composition (protein, fat, lactose, total solids, and non-fat solids) of refrigerated bulk tank milk from 100 dairy farmers located in the south of Minas Gerais state, Brazil, by application of a semi-structured questionnaire.
