used hybrids

Commercial Utility of Hybridization - Hybridization is mainly utilized to evolve new hybrids having beneficial heterosis improve / incorporate a specific desirable character so that such progenies are used in further breeding process and desirable improvement..

A commercial hybrid is a hybrid, where in seeds of F 1 generation are used to grow the crop - so that heterosis is available to improve the performance of cro..

. Some early maturing hybrids with high yielding qualities are Vivek - 9, Pusa early hybrid Makka - 3, JH 3459, KHMH - 175, Kohinoor and Aravalli Mekka - 1. High protein hybrids like Shaktiman - 1 and Shaktiman - 2 are also released. They are useful for baby ..

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..

The offsprings of a hybrid is called filial generation. The first filial generation after hybridization is called F 1 . The seeds obtained from F 1 hybrid could be used to grow second filial generation (F 2 ) hybrid. The generations could be continu..

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..

In the octahedral structure the central metal atom uses inner (n -1) d - orbitals or outer (n)d-orbitals for hybridization. This results ..

Crop improvement by deliberate attempt to cross two parents of desirable characters to incorporate such characters in next generations is called breeding. The entire process of pollination, fertilization and regeneration is kept under control and selected parents are allowed to reproduce only with ..
