Tussilago farfara of family Asteraceae has been worked out cytologically for the first time from India. The presently studied individuals collected from Solang Valley, Kullu District, Himachal Pradesh exist at triploid level with 2n=24 against the earlier highly polyploidy counts of 2n=60 and 2n=72 from outside of India. These individuals depict abnormal meiosis characterized by the presence of trivalents and univalents, unequal distribution of chromosomes and laggards during anaphases/telophases resulting into abnormal sporads and high pollen sterility. The triploid individuals might have originated from a hybridization process involving tetraploid and diploid as putative parents.
