Abstract

Karyotypes of nine Tagetes erecta L. accessions and three Tagetes patula L. accessions were studied. The chromosome numbers of T. erecta and T. patula were 2n=2x=24 and 2n=4x=48, respectively. The karyotype formulae of T. erecta L. ‘Scarletade’ and ‘Perfection Yellow’ are 2n=2x=24=4sm+20m; ‘9901AB’ and ‘Harvest’, 2n=2x=24=2sm+22m; ‘Taishan’, 2n=2x=24=14sm+10m; ‘Marvel’ and ‘Perfection Orange’, 2n=2x=24=24m. The karyotype formulae of T. patula L.:‘GoldenGate’ and ‘Janie’ are 2n=4x=48=4sm+44m; ‘Little Hero’, 2n=4x=48=48m.

 

Key words: Tagetes erecta L., Tagetes patula L., chromosome, karyotype.
