ABSTRACT = {The research was conducted with the aim to identify
the variability <i>in situ</i> of wild and semi-wild morphotypes of <i>Capsicum</i>
spp. that were found growing in different places of Tabasco
and the north of Chiapas States. Morphotypes included “Amashito”
(five types), “Pico de paloma” (two types), “Garbanzo”, “Ojo de sapo”,
“Ojo de cangrejo”, “Colmillo de lagarto” and “Corazón de pollo”.
Such characterization is important because there is an extensive variability
of forms cultivated in the country, resulting from a wide range
of agroecological diversity as well as diverse forms, colours, flavors
and sizes that constitute a valuable collection of genes and a valuable
contribution to gastronomy. We measured qualitative traits like
leaf colour, leaf shape, calyx margin, stem colour, stem shape, plant
growth habit, branching habit, flower position, fruit colour and fruit
shape. Quantitative variables such as plant height, stem diameter,
number of flowers per axil, fruit lenght, fruit width and number of
seeds per fruit were also registered. From the first Principal Component
Analysis (PCA), nine variables were selected as the most
discriminant. A second PCA was performed with these selected
variables and a cluster analysis (CA) was also performed. The three
first principal components explained 58.27% of the total variation.
The cluster analysis ordered the population of chilies in contrasting
groups. These were grouped by species, locality of identification and
the superiority of any (or some) traits that were common in every
group.},
