Abstract
Con el objetivo de evaluar las características agronómicas y agroindustriales de diez genotipos de papa (Solanum tuberosum L.), con pulpa de colores, se cultivaron plantas distribuidas en bloques completos al azar, con tres repeticiones. Como resultados los genotipos 12-4-145, 12-6-158 presentaron rendimientos entre 27,21 y 29 t/ha, periodo de dormancia entre 31 y 41 días, defectos físicos menores a 13,16%. Los genotipos 12-4-72, 12-4-175, 12-4-145, 12-4-35 presentaron alto contenido de materia seca (22,18%), menores defectos (4,71%), menor porcentaje de azúcares reductores (0,12%), mayor días dormancia (58 ddc), menor grado de verdeamiento (2,00). Los genotipos 12-6-158, 12-4-175, 12-4-145, 12-4-143 fueron seleccionados por presentar mayores rendimientos, mejor calidad de fritura, mayor contenido de materia seca, mayores días dormancia, mejor aceptación, y un bajo porcentaje de daños físicos internos y externos.
With the aim of evaluating the agronomical and agro-industrial properties of ten genotypes of potatoes (Solatium tuberosum L.), with colored pulp, various plants were randomly cultivated and distributed throughout full blocks on three separate occasions. As a result of this study, it was determined that the genotypes 12-4-145 and 12-6-158 produced yields between 27,21 and 29 t/ha, with a dormancy period of between 31 and 41 days, and minor physical defects totaling 13.16%. The genotypes 12-4-72, 12-4-175, 12-4-145 and 12-4-35 presented a high content of dry matter (22.18%), minor defects (4.71%), and insignificant percentage of reducing sugars (0.12%), a significant dormancy period (58 dah), and minor levels of re-greening (2.00). The genotypes 12-6- 158, 12-4-175, 12-4-145 and 12-4-143 were chosen as the produced a larger yield, presented and improved frying quality, a greater content of dry matter, an increased dormancy period, better levels of approval, and a minimal percentage of physical internal and external damages.
