Caracterización morfológica de 174 accesiones de Capsicum spp. en CATIE en 2008-2010
El CATIE posee importantes colecciones de recursos genéticos, las cuales se encuentran bajo un acuerdo con el Órgano Rector del Tratado Internacional sobre Recursos Fitogenéticos para la Alimentación y Agricultura. Una de estas colecciones es la colección de Capsicum spp. , la cual cuenta con 905 accesiones.
Este set de datos contiene información de caracterización tomada durante el período de Mayo 2008 a Diciembre 2010. En total, 174 accesiones fueron regeneradas y caracterizadas en CATIE (finca Cabiria, Turrialba, a 608 msnm). La caracterización se realizó siguiendo la lista de descriptores definida por IPGRI-CATIE-AVRDC.
Algunas accesiones tienen un sufijo debido a que en regeneraciones anteriores se obtuvieron frutos con distintas formas (segregación); por lo tanto, la accesión fue subdividida y a cada subgrupo se le asignó una letra distinta. Con el propósito de conservar la mayor cantidad de alelos para regenerar cada accesión se sembraron 40 plantas. En caso de no alcanzarse esa cantidad se incluye un comentario con la cantidad final de plantas sembradas.
Number of days from the first fruit set to the last fruit formation
Observed at anthesis (when the flower is fully open)
Number of days from transplanting until 50% of the plants have fruits in the first and second fork
Average fruit weight yield in 10 plants
Average of 10 fruits
Observe the ease of separation at the time of harvesting
Observe in the basal part of the plant. It is observed when the plant is mature
It is recorded when the first fruit begins to ripen in 50% of the plants
Observed on the youngest mature leaves
Number of days from planting until 50% of the plants have at least one open flower
It is measured immediately after the first harvest, at the widest point
The height is measured up to the first bifurcation, immediately after the first harvest
It is observed in healthy and mature plants. Average of 10 plants
It is recorded before harvest
Average of 10 fruits
It is observed immediately after flowering and at the time of anthesis (when the flower is fully open)
It is observed in immature fruits just before maturity
Observe the ease of separation at the time of harvest
Average of at least 10 fruits per accession chosen at random
Observe in the basal part of the plant. It is observed when the plant is mature
It is observed on mature plants, excluding the first two nodes below the borer
Natural infestations or infections are recorded, with an incidence scale from 1 to 10
Fecha en la cual se realizó la siembra.
