Abstract

Karyotype analysis of Agave americana L. and A. striata Zucc revealed that both the species had 2n = 60 with differences in individual chromosome length, total chromatin length (TCL) and total frequency % (TF%) between the complements of their chromosomes. The identified chromosome pairs were Im, IISm, IIISm, IVSm, Vm, VISm, VIIISt, IXSm, XIISm, XVIISm, XVIIISm, XIXm, XXIm, XXIIm, XXIIIm, XXIVSt, XXVm, XXVISm, XXVIISm, XXIXSm and XXXm in A. americana and IIm, IIISt, IVSm, VIsm, VIISt, VIIISm, IXSm, XIIm, XIIISt, XIVSm, XVSm, XVISm, XVIISm, XIVSm, XXm, XXISm, XXIIISm, XXVm, XXVIISm and XXVIIIm in A. striata. The proposed standard karyotype were 1L1m + 9M8Sm+1St + 16S18m+7Sm+1St + 4S22Sm+1St for A. americana and 2L1m+1Sm + 9M7Sm+2St + 15S1 3m+11Sm+1St + 4S2 2m+2Sm for A. striata.

Key words: Karyotype analysis; Agave americana; A. striata
