Abstract
Polyploidy is thought to be an evolutionary and systematic mechanism for gene flow and phenotypic advancement in flowering plants. It is a natural phenomenon that promotes diversity by creating new permutations enhancing the prime potentials as compared to progenitors. Two different pathways have been recognized in studying polyploidy in nature; mitotic or somatic chromosome doubling and cytogenetics variation. Secondly, the vital influence of being polyploid is its heritable property (unreduced reproductive cells) formed during first and second-division restitution (FDR & SDR). Different approaches either chemical (Colchicine, Oryzalin, Caffeine, Trifuralin, or phosphoric amides) or gaseous i.e. Nitrous oxide have been deliberated as strong polyploidy causing agents. A wide range of cytogenetic practices like chromosomes study, ploidy, genome analysis, and plant morphology and anatomy have been studied in different plant species. Flow cytometry for ploidy and chromosome analysis through fluorescence and genomic in situ hybridization (FISH & GISH) are the basic methods to evaluate heredity substances sampled from leaves and roots. Many horticultural crops have been developed successfully and released commercially for consumption. Moreover, some deep detailed studies are needed to check the strong relationship between unique morphological features and genetic makeup concerning genes and hormonal expression in a strong approach.
