Plant propagation is carried out by sexual or asexual mode of life cycles. The asexual or vegetative reproduction produces genetically identical plants. Multiplication of several horticulturally important crops follows vegetative methods. Production of genetically identical plant cultivars by asexual method is called clonal propagation and genetically identical individuals derived from a single individual by asexual mode referred as clone. Contrast [...]
