The following points highlight the three main factors affecting micro-propagation. The factors are: 1. Genotype 2. Media 3. Cultural Conditions. Factor # 1. Genotype: Physiological conditions of the donor plants influence considerably in the process of morphogenesis. Larger sizes of the meristematic tissues are advantageous. Selecting juvenile parts of the plants yield better results than older ones. The most actively [...]
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 [...]
Molecular Markers in Breeding Programme: The advent of molecular techniques played a significant role in increase our knowledge of cereal genetics and behaviour of cereal genomics. While RFLP markers have been the basis for most work in crop plants, valuable markers have been generated from RAPD and AFLPs. Recently, other improvised molecular marker such as simple sequence repeats (SSR), microsatellite [...]
