Microsatellite markers have been widely used in the quantification of genetic variability and for genetic breeding in Musa spp. The objective of the present study was to evaluate the discriminatory power of microsatellite markers derived from 'Calcutta 4' and 'Ouro' genomic libraries, and to analyze the genetic variability among 30 banana accessions. Thirty-eight markers were used: 15 from the 'Ouro' library and 23 from the 'Calcutta 4' library. Genetic diversity was evaluated by considering SSR markers as both dominant markers because of the presence of triploid accessions, and co-dominant markers. For the dominant analysis, polymorphism information content (PIC) values for 44 polymorphic markers ranged from 0.063 to 0.533, with a mean value of 0.24. A dendrogram analysis separated the BGB-Banana accessions into 4 groups: the 'Ouro' SSR markers from 'Calcutta 4' and 'Ouro' libraries and 'Muísa Tia' accessions were the most dissimilar (93% dissimilarity), while the most similar accessions were 'Pacovan' and 'Walha'. The mean genetic distance between samples was 0.74. For the analysis considering SSR markers as co-dominants, using only diploid accessions, two groups were separated based on their genome contents (A and B). The PIC values for the markers from the 'Calcutta 4' library varied from 0.4836 to 0.7886, whereas those from the 'Ouro' library ranged from 0.3800 to 0.7521. Given the high PIC values, the markers from both the libraries showed high discriminatory power, and can therefore be widely applied for analysis of genetic diversity, population structures, and linkage mapping in Musa spp. MenosMicrosatellite markers have been widely used in the quantification of genetic variability and for genetic breeding in Musa spp. The objective of the present study was to evaluate the discriminatory power of microsatellite markers derived from 'Calcutta 4' and 'Ouro' genomic libraries, and to analyze the genetic variability among 30 banana accessions.

The objective of this study was to determine relationships between insect resistance and some horticultural traits and the implications on selection. A potato population of 11 clonal families derived from crosses between insect resistant and genotypes adapted to the southern region of Brazil was used. The following traits were evaluated: plant size and vigor, incidence of insect attacks on leaves and tubers, tuber yield and appearance components. Phenotypic and genotypic correlations between leaf and tuber resistance were not significant for the population, while phenotypic correlations between the two resistance types were significant for individual families, with exception of the family originated from the cross involving ‘ND263-32’. The incidence of insect attacks on tubers was significantly correlated with tuber yield and appearance in families derived from crosses of ‘NYL235-4’. The manifold correlations of leaf resistance with horticultural traits for all families were significant and unfavorable. |
