Abstract

BAEZA, Carlos  and  MACAYA, Jorge. Karyotypic analysis of Famatina andina (Phil.) Ravenna (Amaryllidaceae): first record of South American Hippeastreae with secondary centromeric constrictions. Gayana Bot. [online]. 2020, vol.77, n.1, pp.59-61. ISSN 0016-5301.  http://dx.doi.org/10.4067/S0717-66432020000100059.

Bulbs were collected from a population of Famatina andina (Phil.) Ravenna in central Chile. Their chromosomes were analyzed and it was observed that the cariotypic formula and chromosomal number are identical to Famatina cisandina Ravenna. Secondary centromeric constrictions were also observed in chromosomes 1, 2 and 7, and the nucleolus organizing region (NOR) was not observed in the long arm of chromosome 7. This is the first report of secondary centromeric constrictions in South American Hippeastreae.
