Catálogo de ajíes (Capsicum spp.) peruanos promisorios conservados en el banco de semillas del INIA - Perú
(Bioversity International, 2013) Libreros, Dimary; Van Zonneveld, Maarten J.; Petz, Michael; Meckelmann, Sven W.; Ríos Lobo, Llermé; Peña Pineda, Karla Mónica; Amaya, Karen; Ramírez, Marleni
El catálogo resume los resultados de estudios agromorfológicos y bioquímicos hechos para un grupo de 35 accesiones de las 39 promisorias de ajíes del banco de semillas del INIA sembradas y caracterizadas en cuatro localidades diferentes, en regiones con un alto potencial para la producción de ajíes: Huaral, Tambo Grande, Piura y Chiclayo, y en la Amazonia peruana: Pucallpa y Ucayali, con la idea de estudiar su comportamiento en los diferentes ambientes.
Generación de innovaciones para mejorar la competitividad y los beneficios de los actores de las cadenas de valor de los ajíes nativos en Bolivia y Perú
(Bioversity International, 2014) Jäger, Matthias; Amaya, Karen
El documento revisa los resultados del proyecto Rescate y promoción de los ajíes nativos en su centro de origen, en el cual se desarrolló un enfoque modelo combinando actividades de investigación y desarrollo para demostrar cómo se pueden mejorar los ingresos de los agricultores de ajíes nativos aprovechando la diversidad que actualmente está siendo subutilizada, y la transición hacia una producción y comercialización diferenciada de alto valor.
Screening Genetic Resources of Capsicum Peppers in Their Primary Center of Diversity in Bolivia and Peru

For most crops, like Capsicum, their diversity remains under-researched for traits of interest for food, nutrition and other purposes. A small investment in screening this diversity for a wide range of traits is likely to reveal many traditional varieties with distinguished values. One objective of this study was to demonstrate, with Capsicum as model crop, the application of indicators of phenotypic and geographic diversity as effective criteria for selecting promising genebank accessions for multiple uses from crop centers of diversity. A second objective was to evaluate the expression of biochemical and agromorphological properties of the selected Capsicum accessions in different conditions. Four steps were involved: 1) Develop the necessary diversity by expanding genebank collections in Bolivia and Peru; 2) Establish representative subsets of ~100 accessions for biochemical screening of Capsicum fruits; 3) Select promising accessions for different uses after screening; and 4) Examine how these promising accessions express biochemical and agromorphological properties when grown in different environmental conditions. The Peruvian Capsicum collection now contains 712 accessions encompassing all five domesticated species (C. annuum, C. chinense, C. frutescens, C. baccatum, and C. pubescens). The collection in Bolivia now contains 487 accessions, representing all five domesticates plus four wild taxa (C. baccatum var. baccatum, C. caballeroi, C. cardenasii, and C. eximium). Following the biochemical screening, 44 Bolivian and 39 Peruvian accessions were selected as promising, representing wide variation in levels of antioxidant capacity, capsaicinoids, fat, flavonoids, polyphenols, quercetins, tocopherols, and color. In Peru, 23 promising accessions performed well in different environments, while each of the promising Bolivian accessions only performed well in a certain environment. Differences in Capsicum diversity and local contexts led to distinct outcomes in each country. In Peru, mild landraces with high values in health-related attributes were of interest to entrepreneurs. In Bolivia, wild Capsicum have high commercial demand.
