The aim of this study is to characterize morphologically the parental and plants and those obtained from the diallel crosses, to identify the variety obtained and to confirm the hybrid nature of these. Three morphological descriptors of root were used to characterize the parental and 68 of the 162 plants obtained from crosses, each with their replication, in total 834 plants were evaluated. Finally 44 hybrids were obtained, 8 plants with no specific hybridization to no identify if there was cross but inheriting only the characters of the female parent or are replications of this, 9 plants with a non-specific hybrid origin unable to determine whether there was hybridization inheriting shared characters by both parents or single characters of the female parent or not; 7 plants whose male parent is not corresponding to the cross, 2 replications of three hybrids and one replication 1 of 1 of...

En el presente trabajo se caracterizan morfológicamente los parentales y las plantas obtenidas a partir de los cruzamientos dialélicos de yacón (Smallanthus sonchifolius), con la finalidad de identificar la diversidad obtenida y confirmar la naturaleza híbrida de estas. Tres descriptores morfológicos de raíz fueron usados para caracterizar a los parentales y a 68 de las 162 plantas obtenidas de las cruzas, cada una con sus respectivas replicaciones, en total se evaluaron 834 plantas. Finalmente se determinaron 44 híbridos, 8 plantas con hibridación no determinada al no identificar si existió cruza, pero que heredaron solo los caracteres del progenitor femenino o son replicaciones de este, 9 plantas con un origen híbrido no específico al no poder determinarse si existió hibridación heredando caracteres compartidos por ambos progenitores o solo caracteres del progenitor femeni...

Physalis peruviana (Golden berry) a native fruit of Peru, is an important Andean agricultural crop. Although classical cytogenetics research on this berry has been conducted there is no precise evidence based on molecular cytogenetic studies. The Fluorescent In Situ Hybridization (FISH) technique was applied to reveal 5S rDNA sites in chromosomes of San Pablo and Celendín populations, Cajamarca, Perú. This research was identified the 5S rDNA locus in the two populations of Golden berry, reporting six signals in 3 pairs of chromosomes which would indicate that the species is polyploid. Likewise, no differences were found in the number of 5S rDNA loci between both populations, so we could point out that they would not be different ecotypes.
