Abstract
El objetivo de la investigación fue determinar el efecto de la interacción de genotipo por ambiente en el comportamiento post cosecha en papas biofortificadas con Fe y Zn en tres localidades (Checras, Viñac y Gorgor) de la Región Lima. Las semillas de 12 genotipos de papa biofortificadas con hierro (He) y zinc (Zn) (Biot-507.311; Biot-633.294; Biot-637.001; Biot-721.074; Biot-721.245; Biot-721.286; Biot-725.024; Biot-725.047; Biot-725.050; Biot735.105;
Biot-767.014 y Biot-871.043) y dos variedades comerciales (Serranita y Yungay) fueron adquiridas del Centro Internacional de Papa (CIP). Se condujo el experimento bajo un diseño de bloques completamente al azar (DBCA) con un arreglo factorial de 14 genotipos x 3 localidades x 3 tiempos de almacenamiento. Las variables evaluadas fueron: pérdida de peso, dormancia, brotamiento y verdeamiento de los tubérculos. La menor pérdida de peso se presentó en el clon Biot-767.014 con 6.8% de pérdida de peso durante los 150 días de almacenamiento en la localidad de Viñac. En la localidad de Checras el clon Biot-507.311 presentó brotamiento de dominancia apical hasta los 150 dda. En la localidad de Gorgor y Checras el periodo de dormancia de los clones fue intermedio debido a que se prolongó hasta los 90 dda. En las tres localidades los clones Biot-725.050 y Biot-735.105, presentaron un ligero verdeamiento hasta los 150 dda. Se concluye que las variables post cosecha están influenciados directamente por el genotipo y ambiente.
The objective of the research was to determine the effect of genotype-by-environment interaction on post-harvest performance of potatoes biofortified with Fe and Zn at three locations (Checras, Viñac and Gorgor) in the Lima Region. Seeds of 12 potato genotypes biofortified with iron (He) and zinc (Zn) (Biot-507.311; Biot-633.294; Biot-637.001; Biot721.074; Biot-721.245; Biot-721.286; Biot-725. 024; Biot-725.047; Biot-725.050; Biot735.105; Biot-767.014 and Biot-871.043) and two commercial varieties (Serranita and Yungay) were purchased from the International Potato Center (CIP). The experiment was conducted under a completely randomized block design (DBCA). with a factorial arrangement of 14 genotypes x 3 locations x 3 storage time. The variables evaluated were: weight loss, dormancy, sprouting and tuber greening. The lowest weight loss occurred in clone Biot767.014 with 6.8% weight los during the 150 days ofstorage at the Viñac locality. At Checras, clone Biot-507.311 showed apical dominance sprouting up to 150 days. At Gorgor and Checras the dormancy period of the clones was intermediate because it lasted until 90 dda. In the three locations, the Biot-725.050 and Biot-735.105 clones showed a slight greening up to 150 dda. It is concluded that post-harvest variables Are directly influenced by genotype and environment.
