There is a great potential of cell and tissue culture techniques in plant improvement, provided plants can be readily regenerated in large numbers. Mendel onward, the hybridization had become the key method of crop improvement. Tissue culture is an in vitro culture of cells, tissues, organs or whole plant or plant parts (leaf, stem, root, ower, anther , ovule, etc.) Plant tissue culture comprises a set of in vitro techniques, methods and strategies that are part of the group of technologies called plant biotechnology. culture in crop Many of these are reaching the limits of their improvement by traditional methods. Plant organ, tissue and cell culture procedures have developed rapidly in the last half-century since the pioneering efforts of Gautheret, White and Nobecourt. Dept.

Mutagenic agents, such as radiation and certain chemicals, then can be used to induce mutations and generate genetic variations from which desired Tissue Culture: The growth of tissues of living organism in a suitable culture medium (in vitro)I is called tissue, culture. Transformation methods for plants were invented in 1983 and rapidly translated to all major and most minor crops. Plant tissue culture is widely used to produce clones of a plant in a method known as micropropagation . 1994). In addition to this, tissue culture methods are now being used for the production of secondary metabolites in vitro.

Introduction Plant tissue culture comprises a set of invitro techniques methods, strategies that are a part of plant Biotechnology. The typical crop improvement cycle takes 10–15 years to complete and includes germplasm manipulations, genotype selection and stabilization, variety testing, variety increase, proprietary protection and crop production stages.

The first of these, the reduction of the duration of breeding programmes, makes use of tissue culture. Application of tissue Hybridization was first of all practically utilized in crop improvement by German botanist Joseph Koerauter in 1760. Tissue culture had been exploited to create genetic variability, to improve the health of planted material, increase the number of desired germplasm. Role of mutation breding in crop improvement 1. CREDIT SEMINAR on Presented by- Sanjay Kumar M.Sc. The plant part which is used in regeneration is called explants). Definition of Plant Tissue Culture: Plant tissue culture has a great significance in plant biotechnology specially in the crop improvement programmes. Crop Improvement Through Genetic Engineering 2. 4. improvement This paper mainly deals with a comprehensive review on the role of plant tissue culture in crop improvements and food security in Indian context. Tissue culture will continue to playa key role in the genetic-engineering process for the foreseeable future, especially in efficient gene transfer and transgenic plant recovery (Hinchee et al. Phil., (Botany). Haploid tissue cultures are most often obtained by culturing microspores, pollen grains, and anthers (Figure 9.2F). The adoption of new technologies such as plant tissue culture and recombinant DNA may help in achieving some of the goals to increase food production.
