Abstract

Asplenium ruta-muraria, Woodsia asiatica and Cheilanthes argentea collected in Russian Altai showed the chromosome numbers of n=72_II, 2n=82 and 2n=60 (n=30_II), respectively. Sporophytes of Asplenium ruta-muraria and Woodsia asiatica were produced apogamously on agar medium and their mitotic chromosome numbers were 2n=72 and 2n=41, respectively. The haploid sporophyte formation of Asplenium ruta-muraria and that of Woodsia asiatica were reported here for the first time.
