Role of biotechnology in improvement of vegetable crop
Biotechnology having
an important role as a modern tool for improving crops since last 30 years. By
this a single commercially important crops are develop by using
biotechnological tools eg: somatic hybrids, cybrids, GE variety in india .
Vegetable production : modern
biotechnology which develop to use high yielding product and more nutritive
crop varieties also , improve their resistance power to diseases , and also decrease the use of
fertilizers and other chemical substances. Crop varieties are improve by their
clonal propagation and their improve their genetic material as well .To affects
the plant and animal traits by traditional methods like cross pollination,
grafting , and cross breeding but now biotechnology helps to made quickly , on
molecular level through additional and deletion of any gene or introduction of
any new foreign gene .
1. For eg:
Bacillus thuringiensis microbe [ pest resistant crop ] which produce toxic
protein which is harmful for the insects . that gene produced protein by the
microbes is isolated and transfer into the crop by genetic engineering and its
transfer into by potato and cotton.
Bt
protein is not harmful for human so its easier to transgenic crop for farmers .
2. To increase
their ripening power of tomatos . these are also genetically modified .
3. Many rice
varieties also. Like golden rice.
4. Nicotina
tobaccum it is also genetically modified
