Abstract

PALACIOS CASTRO, Shirley  and  GARCIA DAVILA, Mario Augusto. Morphologic characterization of 93 accesions of Capsicum spp of germoplasm bank of National University of Colombia - Palmira. Acta Agron. [online]. 2008, vol.57, n.4, pp.247-252. ISSN 0120-2812.

Morphologic characterization of 93 Capsicum accessions of Capsicum spp., from 11 countries (Bolivia, Brasil, Colombia, Costa Rica, Cuba, Ecuador, Guatemala, Guyana, México, Perú and El Salvador) and representative of four species (C. annuum, C. baccatum, C. chinense, C. frutescens), 21 IBPGR's descriptors were used (six quantitative y 15 qualitative; eight of vegetative traits, three of flower traits and ten of fruit and seed traits). Morphologic characterization permited confirm the presence of intragenetic variability, in special for of plant architecture descriptors, reproductive structures and production, wich explain the 78% of the total variability. Dice's distance permitted groups formation based in their origin and flower and fruit traits, but didn't permit to interespecific discrimination. Narrow genetic distances among C. annuum, C. frutescens y C. chinense can indicate these three species conform only one morphological group.

Keywords : Capsicum annuum; C. baccatum; C. chinense; C. frutescens; cultigroup; morphologic characterization.
