The frequency of haploid production following the inlerspecific pollination of eight tetraploid pot<lto cuhi var~ (Solanum wherosum subsp. IIlberosum) with Solanum phureja clone 1.22 was investigated. A total of 185 haploids were produced with an overall haploid frequency of 3.9 haploids/lOO [ruits. The haploid frequency was affected by the genotype of the maternal parent. Atlantic, NDR60-2, Su...

Due to the high genetic variability of potato, starch can exhibit different properties interest industry. With present investigation, it is intended know these differentiating characteristics in comparison with commercial sources that be useful sectors. Therefore, objective this research was establish a between potato starches extracted from native varieties (Solanum phureja) and corn starches....

Solanum phureja es una variedad andina de papa con un alto potencial exportación, gracias a sus propiedades nutricionales, organolépticas y funcionales; sin embargo, su tiempo vida en percha muy reducido. Esta investigación tuvo como objetivo evaluar el tratamiento este tubérculo radiación gamma para retardar la brotación. Se empleó diseño factorial 4×2 seleccionar mejor combinación dosis (0, 8...

The PIN family of trans-membrane proteins mediates auxin efflux throughout the plant and during various phases of plant development. In Arabidopsis thaliana, the PIN family comprised of 8 members, divided into "short" and "long" PINs according to the length of the hydrophilic domain of the protein. Based on sequence homology using the recently published potato genome sequence (Solanum tuberosum...

The genetic control of dormancy is poorly understood in most plant species, but dormancy is a prominent feature for the potato industry. We used the microtuber system, in which tubers were produced in vitro and stored at 20°C, to perform quantitative trait locus (QTL) analysis for dormancy and gibberellic acid (GA3) content in an F1 population consisting of 178 genotypes derived from an intersp...

Polyploidy is remarkably common in the plant kingdom and polyploidization is a major driving force for plant genome evolution. Polyploids may contain genomes from different parental species (allopolyploidy) or include multiple sets of the same genome (autopolyploidy). Genetic and epigenetic changes associated with allopolyploidization have been a major research subject in recent years. However,...
