commercial utility of hybridization

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 d..

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..

. Possibility of crossing distinct species of same genera or different genera has been found mainly due to somatic hybridization techniques. Somatic hybridization is commercially useful in inducing somatic male sterility or cytoplasmic male sterility (CMS) by fusion of..

Large number of genetic replicas of rare hybrid or sterile valuable plant can be produced asexually by culturing shoottips. Since propagation is vegetative, the problems of heterogeneity, pollination, divergent inheritance, chromosomal and gene transformations are completely avoided in s..

Control of Ozone Depletion - Policy decisions are already taken in India to undertake technology developments for alternatives to CFCs. Two CSIR laboratories - National chemical laboratory and Indian Institute of Chemical technology are working on this. Along with this, parameters for design modifi..

Renewable sources of energy are produced continuously in nature and are non-depletable. Sources like water, sunlight, air, tidal energy, nuclear energy, geothermal power, are not exhaustible. A non-renewable source of energy gets depleted over a certain period of time, and is not easily replaceabl..

Nitrogen Fixing Organisms - Some bacteria are known to fix the atmospheric nitrogen for their own biological activity. This natural phenomena is commercially utilized to increase the nutrient supply to crops. There are two types of nitrogen fixing bacteria. They are a) Symbiotic..

. For example, more land was converted to cropland in the thirty years since 1950 than had been converted in the whole of the period 1700 to 1850 (The Biodiversity Synthesis Report in the UN Millennium Ecosystem Assessment project). Forty percent of the earth's land surface is now used to grow crop..

Forest Resources - Forests are the most important resource of our globe. Naturally formed forests are found in such parts of globe - where the factors of plant growth have been ideal for several centuries. For this reason, they are mostly found in regions of high rainfall and regions of high altitu..
