New chromosome number reports in some Polypetalous species from Kashmir Himalayas

Abstract

As a part of our programme to explore and evaluate genetic diversity of flowering plants from Kashmir Himalayas, at present 150 species of Polypetalae have been meiotically worked out. It brings to light new/ varied chromosome number reports for 30 species. The taxa being cytologically worked out for the first time on world-wide basis include four species as Pleurospermum densiflorum (n=11), Sedum wallichianum (n=36), Astragalus strobiliferus (n=8), Hedysarum cachemirianum (n=8) and one variety as Rosa macrophylla var. minor (n=7) along with new intraspecific cytoypes in case of six species as Cardamine loxostemonoides (n=8), Fumaria indica (n=6), G. ocellatum (n=14), Rosa pendulina (n=7), Sedum ewersii (n=36) and Sisymbrium orientale (n=14). Nineteen species which are being cytologically worked out for the first time from India include Barbarea intermedia (n=8), Corydalis cashmeriana (n=8), Descurainia sophia (n=10), Epilobium alpinum (n=9), E. angustifolium (n=18 and 36), E. cylindricum (n=18), E. hirsutum (n=18), E. palustre (n=9), Geranium sibiricum (n=14), Hypericum perforatum (n=16), Impatiens bicornuta (n=9), Lupinus polyphyllus (n=24), Oenothera drummondii (n=7), Rorippa islandica (n=8), Sisymbrium strictum (n=7), Rubus caesius (n=7), R. idaeus (n=7), R. saxatilis (n=14) and Myricaria germanica (n=12).
