摘要
Two diploid cytotypes of Chenopodium album have earlier been proposed as the probable ancestors of hexaploid C. album in Gangetic Plain of West Bengal on the basis of cytomorphological data. The present study with the diploid cytotypes of C. album (one broad leaved, another narrow leaved), one wild species, C. murale and the hexaploid C. album utilizing parameters like seed protein, isozyme, RAPD, tissue culture along with conventional cytomorphological data supports our earlier hypothesis of allopolyploid origin of hexaploid C. album. The results indicate that all the three diploid progenitors have contributed for the evolution of present day semi-cultivated hexaploid C. album. This study further suggests that the diploid cytotypes had been evolved sympatrically.
