La kiwicha es considerada un super alimento por su alto valor nutricional y sustancias bioactivas como, proteínas, fibra, compuestos fenólicos, flavonoides, almidón, antocianinas, entre otros. El Ministerio de Desarrollo Agrario y Riego (MIDAGRI) a través del Instituto Nacional de Innovación Agraria (INIA), tiene la misión de conservar los recursos genéticos de uso agrario, y fomentar su puesta en valor y producción. Además, es responsable del Banco de Germoplasma más importante del Perú en materia de agrobiodiversidad, donde se conservan 552 accesiones de kiwicha pertenecientes a las especies Amaranthus cruentus, A. caudatus, A. hypochondriacus, A. hybridus, A. retroflexus y Amaranthus sp. El presente documento se elaboró en base a los resultados obtenidos en diversos trabajos de conservación y caracterización agromorfológica de kiwicha, desarrollados en la Estación Expe...

Smallanthus sonchifolius (yacon) is a functional food native to the South American Andes. Its tuberous root and leaves are the main parts consumed; however, few studies have been carried out on its phenotypic variability. This study aimed to characterize 214 yacon accessions from the Germplasm Bank of the Instituto Nacional de Innovación Agraria (INIA), Peru. Twelve qualitative and seven quantitative variables were used. Accession Y-74 showed the largest leaf dimensions, while Y-28 showed the highest productivity per plant. Multiple correspondence analysis and principal component analysis revealed that the variables propagule color, leaf shape, root pulp color, leaf length and width, root weight per plant, and yield contributed significantly to the discrimination and identification of promising accessions. The geographical grouping of the accessions showed differences between accessions...

Amaranth is a promising crop for the Cajamarca region and Peru. The National Institute of Agrarian Innovation (INIA) from Peru preserves a national collection of 552 amaranth accessions; however, there needs to be a detailed study of the morphology of these materials. In this research, 65 accessions were morphologically characterized based on their place of origin, using 21 descriptors standardized by INIA-Peru. The clustering of accessions and principal component analysis showed the presence of 38 groups and a duplication rate of 41.5% of accessions at a taxonomic distance of 0.62. In addition, 18 morphological characters that significantly contributed to morphological variability were identified and explained by the first six principal components. Due to the scarcity of studies on amaranth, it is recommended to conduct more characterization and molecular studies to obtain better approx...
