BACKGROUND Cultivated bananas are large, vegetatively-propagated members of the genus Musa. More than 1,000 cultivars are grown worldwide and they are major economic and food resources in numerous developing countries. It has been suggested that cultivated bananas originated from the islands of Southeast Asia (ISEA) and have been developed through complex geodomestication pathways. However, the...

Twenty-five microsatellite markers uniquely differentiated 35 avocado cultivars and two wild relatives. Average heterozygosity was high (60.7%), ranging from 32% in P. steyermarkii to 84% in Fuerte and Bacon. In a subset of 15 cultivars, heterozygosity averaged 63.5% for microsatellites, compared to 41.8% for restriction fragment length polymorphisms (RFLPs). A neighbor-joining tree, according ...

Cultivar characterization for fruit trees certification requires fast, efficient and reliable techniques. Microsatellite markers (SSR) were used in the molecular characterization of 29 Prunus spp. rootstocks. The DNA from the rootstocks was analyzed using five pre-selected SSR primers (UDP96-005, UDP96-008, UDP96013, UDP96-18 and UDP98-414) and revealed 81 alleles, which allowed each genotype t...

morphological and pomological features were studied for two consecutive years in wild apricot seedlings grown under macedonian environmental conditions. the population comprised of 19 seedlings, i.e. genotypes, that showed notable fruit and tree traits. their flowering time and desirable fruit quality features were determined in comparison with ‘hungarian best’. in all genotypes, flowering occu...

world apricot (prunus armeniaca l.)  production is increasing steadily due to breeding of new high yielding cultivars in different countries. more recently, breeding programs have been modified according to consumers’ demands and also improvement in resistance to diseases (sharka, monilinia etc.), frost damages, and determination of self-(in) compatibility. in this study, fourteen apricot breed...

ten solanum tuberosum cultivars and accessions from 11 wild solanum species were evaluated for their tolerance to salt (200 mm nacl or 100 mm na2so4), drought (35% peg), cold (-4ºc) and heat (37ºc). evaluation was based on electrolyte leakage from de-tached leaves of in vitro plantlets. testing involved a rinsing treatment with three changes of distilled water to remove electrolytes from leaf a...

to evaluate the morphological diversity of some almond cultivars and genotypes, an experiment was carried out on 55 iranian and foreign genotypes. twenty-nine quantitative and qualitative characteristics of nuts and kernels as well as 4 phenotypic characteristics of almond trees were evaluated. analysis of variance and means comparisons indicated that all the characteristics of the examined cul...

Analysis of DNA polymorphisms allows for the genetic identification and precise discrimination of species with a narrow genetic base such as common bean. The primary objectives of the present study were to molecularly characterize commercial common bean varieties developed at various research institutions using microsatellite markers and to determine the degree of genetic diversity among the be...
