Tomato (Solanum lycopersicum) is a crop of global importance that has center of origin in Peru, with 11 species of wild relatives (CWR) occurring in the country. These CWR contain genetic material that could be used to improve currently cultivated species, and that is usually stored ex situ in germplasm banks. Hence, assessing the representativeness of germplasm banks is important to strengthen genetic improvement of tomatoes as well as their resilience to globally changing conditions. Here, we used gap analysis methodology on the 11 species of tomato CWR occurring in Peru. This methodology consists in seven steps that consider representativeness in terms of herbaria/germplasm banks, geography and environments within the country, in order to establish conservation priorities. We also assessed conservation priorities for the Instituto Nacional de Innovación Agraria (INIA), which is the m...

El Ministerio de Desarrollo Agrario y Riego (MIDAGRI), a través del Instituto Nacional de Innovación Agraria (INIA) conserva una de las colecciones más importantes de tomate silvestre en el Perú. Tal es así que, la Dirección de Recursos Genéticos y Biotecnología (DRGB), por intermedio de la Subdirección de Recursos Genéticos (SDRG) custodia un total de 156 accesiones de tomate silvestre que corresponden a siete especies: Solanum pimpinellifolium, S. pennellii, S. corneliomuelleri, S. neorickii, S. chmielewskii, S. habrochaites, S. lycopersicum var. cerasiforme y S. lycopersicum var. lycopersicum, que poseen rasgos de interés agronómico y concentran genes de respuesta positiva a factores bióticos (plagas) abióticos (estrés hídrico, salino, frío, calor, etc.). Con la finalidad de mostrar y valorar la diversidad morfológica del tomate silvestre del Perú, el INIA presenta ...

In this work, 31 native Peruvian chili peppers were evaluated for their agro-morphological characteristics and sensory attributes. The descriptive sensory analysis (DSA) was used to evaluate the 31 chili pepper samples based on their acid, bell pepper, sweet, tomato, apple, citrus, fruity, herbal, oregano and passion fruit attributes. The data obtained from the DSA enabled the grouping of these 31 chili peppers into six groups based on their different sensory attributes, such as fruity, bell pepper and herbal. The most abundant group (12 of the 31) had the bell pepper, apple, herbal, fruity and sweet attributes. Each group contained different species and different physical appearances, indicating that species or different forms of chili pepper do not define that sensory attribute. Considering the fact that Peruvian peppers are in high demand, the results achieved would be useful for grow...
