Improvement in Yield
Gene technology plays important role in increasing the productivity of food, fibre and vegetable crops ensuring food security which is essential for international peace and stability. Thus it is an important mean to fight hunger.
The transgenes generally are not yield enhancing genes. The increase in yield or productivity is achieved by controlling losses caused by various insects, diseases and abiotic factors. Gene technology is expected to keep pace in food production with increasing would population.
Improvement in Insect and Disease Resistance
In crop plants heavy yield losses are caused every year due to insect and disease attack. Moreover, insecticides and pesticides which are used to control insects and diseases are expensive and have adverse effects on other beneficial organisms (parasites and predators).
Gene technology has played key role in developing insect resistant cultivars in several crops. For example, in cotton bollworm resistant cultivars have been developed by transferring a gene from soil bacterium Bacillus thuringiensis into cotton plants. This leads to saving substantial amount on insecticidal chemicals. Moreover, the technology is environmental friendly.
