Abstract
The information regarding chromosome counts and meiotic behavior is important to understand the plant evolution and diversification. Keeping in view the importance of such studies the present investigation has been carried out. During the present study four populations of Ferula jaeschkeana Vatke have been investigated in terms of chromosome count, meiotic behaviour, pollen fertility and seed set. The present study revealed that the species is diploid with chromosome number of 2n = 2x = 26, which differed from the earlier records reported in the species, depicting that two cytotypes are present in species. During the present investigation translocation heterozygosity and chromosome bridges were observed. Chromosomal stickiness, cytomixis, univalent and multivalent formation, lagging chromosomes, polysporad formation and formation of micronuclei were also observed which results in abnormal microsporogenesis, reduced pollen fertility and seed set in the species.
