A uva de mesa no submedio Sao Francisco ocupa uma area cultivada de cerca de 4.500 ha, dos quais cerca de 85% sao explorados com a cultivar Italia. As condicoes edafoclimaticas dessa regiao favorecem a producao de uva de mesa durante todo o ano. Diversos fatores causam perdas na qualidade e conservacao pos-colheita, sendo a deterioracao patologica responsavel por serios prejuizos economicos. A uva e atacada por varios microorganismos durante as fases de producao. Um levantamento dos fungos pos-colheita foi realizado em 193 amostras de uva cultivar Italia, produzidas nesta regiao durante o periodo de 1994/96, para determinar a incidencia e a frequencia de fungos associados a deterioracao patologica pos-colheita da uva, apos o periodo de armazenamento. As caixas de uva foram coletadas ao acaso, periodicamente, nas lavouras da regiao e armazenadas em camara fria a temperatura entre 2-4oC, com umidade relativa entre 85-95%, durante 39 duas, Detectaram-se onze generos de fungos associados a deterioracao patologica pos-colheita, dos quais os mais frequentes foram: Cladosporium (67,9%), Alternaria (42,5%); Aspergillus (37,3%), Penicillium (25,9%) e Rhizopus (22,3%). |

Conventional methods for the selection of papaya inbred lines are time-consuming. Procedures involving the use of molecular markers can reduce this time considerably, by indirect selection of homozygous plants. The objective of this study was to use microsatellite markers in marker-assisted selection (MAS) to develop new papaya inbred lines, and categorize the inbred lines into useful groups based on the molecular profiles and agronomic traits. Thirty-six lines from F4 (Calimosa × Common papaya) and S3 derivate from open-population accessions of germplasm, and 6 controls were used for the molecular analysis with 27 microsatellite primers. Twelve polymorphic and 15 monomorphic microsatellite primers were identified, allowing the identification of 59 alleles, with an average of 2.19 alleles per primer. The observed heterozygosity values (Ho) were low for both the markers (0.00-0.24) and the individual lines (0.00-0.19). The inbreeding coefficient (f) ranged from 0.80 to 1.00. Eleven papaya inbred lines and checks (landrace, cultivars, and other pure lines) showed complete inbreeding (f = 1). A broad genetic variability for all agronomic traits analyzed, especially for productivity (10.34-86.39 t ha-1), was observed and was confirmed using agronomic and molecular data simultaneously to group the new papaya inbred lines and checks. Hierarchical and silhouette-width method using Gower's dissimilarity revealed 9 major clusters. Despite the fact that self-pollination and selection lead to reduction of genetic variability, papaya inbred lines are proved to be genetically diverse representing a large proportion of the genetic variation occurring in ?Solo? and ?Formosa? groups. This seems to be promising for success in further developments of new hybrids in breeding programs. MenosConventional methods for the selection of papaya inbred lines are time-consuming.
