MEDINA-SANTOS, Lucero Carolina et al. Characterization of chia collections from the western region of Mexico. Rev. Mex. Cienc. Agríc [online]. 2019, vol.10, n.8, pp.1837-1848.  Epub 05-Fev-2021. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v10i8.1955.

Chia is a very valuable resource since it is the main source of unsaturated fatty acids, mainly α-linolenic, in addition to protein and fiber. In this investigation, seven collections were made in seven locations for study and comparison. Seed size were measured, thousand seed weight, volumetric weight, color, germination percentage and oil extraction for chromatography analysis. The collection of cultivated chia from Guanajuato showed greater variability in seed size and that of Roque la minor. The wild collections had the smallest seed size. The cultivated one of Guanajuato has the greater weight in seed and the wild ones the minor, the latter did not germinate, but the domesticated ones did. There were no differences in volumetric weight; however, there were differences in chromatograms (HPLC) and in physical characteristics and color variation in domesticated ones, including white seeds. This prospective research shows that the variability present in wild and cultivated chia can be used for plant breeding.
