Abstract

BAEZA, Carlos; CARRASCO, Pedro  and  VILLALOBOS, Nicolás. CHROMOSOMAL NUMBER OF A POPULATION OF ALSTROEMERIA PELEGRINA L. (ALSTROEMERIACEAE), ENDEMIC SPECIES OF CHILE. Chil. j. agric. anim. sci. [online]. 2020, vol.36, n.2, pp.117-120.  Epub July 27, 2020. ISSN 0719-3882.  http://dx.doi.org/10.29393/chjaas36-9nc30009.

There are previous cytological studies in Alstroemeria pelegrina, an endemic species of Chile, but none of them clearly indicates the location of the material studied. A population of Alstroemeria pelegrina, collected from Los Molles (Region of Valparaíso), was analyzed cytotaxonomically. It was found that this population presents a 2n = 16 chromosomes and a caryotypic haploid formula 3m + 1sm + 2st + 2t. By comparing the biometric data and asymmetry indices of the karyotype of this population with previously published data, it is concluded that it is definitely the same species.

Keywords : Alstroemeria; chromosomes; caryotypic formula; Los Molles; Chile.
