The quality of potatoes for processing depends on varietal, environmental and crop management factors, and the consumption of potato products has increased.The objective of the research was to determine the effect of calcareous amendments on the production and frying quality of potatoes potato cv. Bicentenaria under high Andean conditions.  The research was carried out in the rural community of Canín at Checras district (Lima) altitude of 3880 masl. The climate of the locality is humid and cold, with an annual rainfall of 800 mm and acid soils (pH 5.0) of sandy-clay texture. Five liming treatments and a control without liming were applied to the soil (agricultural lime 500 kg ha-1 and carbonatite 500, 1000, 1500 and 2000 kg ha-1). Agronomic and biochemical characteristics of the tuber were evaluated and sensory analysis was performed for potato frying. Data were analyzed statistica...

The industrialization of potatoes in Peru constitutes a business opportunity to increase the supply of processed potatoes, generating added value for small producers. For this reason, it is important to have varieties suitable for frying and thus supply the potato value chain for the processing industry (french fries) and snacks (flakes). It is described the origin and genealogy of the clone UH-24 (“Bicentenaria”), its agronomic characteristics through the identification analysis, the way how it developed and multiplied in the greenhouse and in the field, as well as the evaluation process through the analysis of adaptation and efficiency in four environments of Lima region. The potato variety Bicentenaria has good production and adaptation capacity in the central coast of Peru, with a mean tuber yield of 43.2 t ha-1, compared to the commercial varieties Canchán and Diacol Capiro wit...

Ulcumano, which is native to South America, is an important conifer in Peru. Molecular studies are scarce, limiting modern breeding and appropriate conservation activities. Currently, molecular markers are widely employed to explore genetic structure and diversity parameters of plant species in a fast and precise manner. The objective of this study was to analyze the genetic diversity and population structure of ulcumano in Peru by using DNA-based molecular markers. Nine Randomly Amplified Polymorphic DNA (RAPD) markers were used, while 95 individuals of ulcumano were sampled from three departments of Peru. A total of 265 DNA fragments were manually scored, but 247 of them were kept after removing the non-polymorphic markers. Genetic distances were calculated using R software based on Provesti´s coefficient. A dendrogram was obtained using the UPGMA clustering algorithm, showing no clea...
