ABSTRACT.
The Karyotype of Alstroemeria diluta Ehr. Bayer subsp. chrysantha (Alstroemeriaceae)

Carlos M. Baeza1*, Eduardo Ruiz1, and Patricio Novoa2
 

The karyotype of Alstroemeria diluta subsp. chrysantha Ehr. Bayer from Chile was examined. The species has 2n = 2x = 16 chromosomes, with 4m + 4sm + 2st-sat + 4t + 2t-sat. The reported karyotype is very asymmetrical (AsK % = 71.4 and Syi = 40.0%). This karyotype is similar to that published previously for Alstroemeria graminea Phil.

Keywords: Alstroemeria, karyotype, ornamental plant, Chile.
