Abstract ‘SCS453 Noninha’ and ‘SCS454 Carvoeira’ are new banana cultivars derived from the subgroup Prata (AAB). In comparison with the latter, ‘SCS453 Noninha’ has a low pseudostem height, 'SCS454 Carvoeira' a high yield and both unchanged fruit characteristics. Both also have increased resistance to Panama wilt and ‘SCS454 Carvoeira’ to Sigatoka.

Quarenta e sete cultivares de ameixeira japonesa (Prunus salicina) foram genotipadas com a utilização de oito marcadores microssatélites, objetivando obter o perfil genético (DNA fingerprinting), distinguir e caracterizar o grupo de cultivares possuidores da maior variabilidade genética da espécie. Os oito locos SSR amplificaram 104 alelos (8 a 21 alelos por loco, média 13). O conteúdo de polimorfismo variou de 0, 680 a 0, 886 (média 0, 803). A heterozigosidade observada (Ho) variou de 0, 529 a 0, 915 (média 0, 07). A Probabilidade de Identidade (I) para cada loco variou de 0, 019 a 0, 113 (média 0, 054) e a Probabilidade de Identidade combinada foi de 2, 66 x 10-11. O Poder de Exclusão dos oito locos foi 99, 99976%. 57 alelos de 104 apresentaram frequência menor que 0, 05. As baixas frequências alélicas contribuíram para aumentar a distinguibilidade da análise. Os resultados obtidos irão auxiliar na identificação de parentais para cruzamentos, clones segregantes com potencial de cultivares e proteção de cultivares.

Forty-seven Japanese plum (Prunus salicina) cultivars were genotyped with eight microsatellite markers, aiming at obtaining the DNA fingerprinting profiling, distinguishing and characterizing a representative set of Japanese plum cultivars. The eight SSR loci amplified 104 alleles (8 to 21 alleles per locus, mean 13). Polymorphism Information Content (PIC) ranged from 0.680 to 0.886 (mean 0.803). The observed heterozigozity (Ho) ranged from 0.529 to 0.915 (mean 0.770). Probability of Identity (I) of each locus ranged from 0.019 to 0.113 (mean 0.054). The combined Probability of Identity was 2.66 x 1011, and the Power of Exclusion of the eight loci was 99.99976%. 57 out of 104 alleles showed frequency lower than 0.05. These low allele frequencies contributed to raise the distinguish ability of plum cultivars. These results will contribute, as excellent descriptors, to select parental for crossings, to perform early identification of segregating clones with potential to be cultivars, and to protect the cultivars.
