The objectives of this study were to examine the expected response to selection for reducing-sugar content after cold storage in three hybrid populations, to determine whether these populations included clones low in reducing sugars, and to investigate the effectiveness of indirect selection for chip colour based on selection of sugar content after cold(More)
Producing large quantities of high quality mini-tubers at low cost is essential for an economically viable supply of seed potatoes. Here we systematize the technical and economic aspects of aeroponics and provide a benchmark comparison of this technology with other mini-tuber production systems as developed in Latin America: conventional, semi-hydroponics,(More)
The present study assessed a commercially available, enzymatically based blood glucose monitor for the rapid determination of processing quality of tuber samples taken directly from storage. This monitor is based on reflectance photometry of a disposable test strip for a chromogen produced during the oxidation of glucose. The influence of storage(More)
The objective of this work was to characterize 27 potato genotypes, using molecular markers. Polyacrylamide gel electrophoresis, RAPD techniques and isozymes of esterase, phosphoglucomutase and soluble proteins were analyzed in tubers, and isocitrate dehydrogenase, aspartate transaminase, phosphoglucomutase and peroxidase, in leaves. Eighteen primers were(More)
Progenies from crosses of ND860-2, a low reducing sugar clone, with two potato cultivars (Trent and Onaway), differing in reducing sugar content, as well as the progenies of the parents selfed, were examined for reducing sugar content. Tubers were assessed after storage at 12 C for 10 weeks (regular storage) and 4 C for 10 weeks followed by reconditioning(More)
The objective of this study was to investigate the response to selection for chip colour after harvest (CH), storage at 12.8°C (CR) and at 3°C (CC) in three hybrid populations. Population 1 was derived from crossing ND860-2 (cold chipper) with F58089 (regular chipper), Population 2 was obtained from crossing ND860-2 with Russette (nonchipper), and(More)
