how ptc help in micropropagation of hybrid plant

Micropropagation - It refers to artificial propagation of plants vegetatively through the culture of cell or tissue. It is most useful, when normal propagation takes long time or the success in fertilization is very poor as seen in many valuable plants useful in agricu..

This type of hybridization is more for scientific interest than for any other use. Raphonobrassica, Rabbage, Triticale, Sugarcane-sorghum (jowar) are some examples of this type of crossin..

. Use of commercial hybrids invariably involves inbred plants as parents -which means parental purity is maintained by not allowing pollen from other varieties to fertilize. The success of hybrid crop and its heterosis is much dependent on purity of parents. As against..

Plant Tissue Culture - It refers to culture or growing the plant tissues. Plant tissue culture is developed as a separate branch of science - ever since the potentiality of each cell or tissue of plant to grow into a separate organism has been recognised. Tis..

In the plant Mirabilis jalapa, commonly called as four'o clock plant, the inheritance of flower colour is an example for incomplete dominance. The plant produces two types of flowers red coloured and white coloured. This condition is an example for a pair of contrastin..

Hybridisation is the technique of introducing characters of two desirable plants into a single offspring (hybrid) by means of artificial pollination. This involves crossing of genetically dissimilar plants..

Protoplast is a cell without cell wall. In plants, the cells are invariably surrounded by thick cell wall made of cellulose and pectin. During the process of tissue culture and using it for crop improvement, cell wall acts as a barrier to induce mutations or some times to develop the call..

Much before the advent of modern biotechnology, there were several practices that were commonly followed. Breeding (hybridisation) of plants and animals to change the genotype and phenotype of the hybrids is probably the oldest and the most widely used technique of genetic engin..

. The callus is transferred to other medium that contains different hormones for differentiation to occur. This differentiated mass of tissue is called the embryoid which grows into the new plantlet. The plantlets are then planted in pots and then in the fields. Here are some terms used i..
