During the present course, detailed male meiosis, morphological observations and distribution pattern have been studied of two different species of Argemone (A. mexicana and A. ochroleuca). Six populations of Argemone mexicana have been collected from different localities of Rajasthan and Himachal Pradesh of which two populations from Talmata and Boh (H.P) depicts the diploid cytotype (2n=2x=14), one population from Nakki lake, Mt. Abu (Rajasthan) shows the tetraploid cytotype (2n=4x=28) whereas three populations from different localities of Rajasthan shows the octaploid cytotype (2n=8x=56) of the species. Octaploid cytotype of the species adds the new chromosomal report on worldwide basis. Detailed meiotic analysis of diploid cytotype shows the presence of meiotic irregularities like chromosomal stickiness, chromatin bridges, abnormal microsporogenesis and heterogenous sized pollen grains while one octaploid cytotype from Chappar shows secondary associations. Meiotic analysis of A. ochroleuca collected from different localities of Rajasthan shows the chromosomal count of 2n=56 which is in conformation with the previous reports from India and outside India.
