INTRODUCTION
Primary food security is entirely dependent on the volume of rice production
Growth of rice production was much faster than the growth of population
Cultivable land is continuously reducing day by day Bangladesh has more than doubled the production of
rice because of modern variety

OBJECTIVES To know about the modern rice varieties developed
by different Bangladeshi organization To Promote higher productive, cost effective and
environmentally sustainable varieties of rice To improve the food security in Bangladesh

DISCUSSION
What is modern variety?
Characteristics of modern rice varieties

Every country should have their own food security
Food Security: When all people at all times have access to sufficient, safe, nutritious food to maintain a healthy and active life then it called food security.

Things affecting food security:
1. Flood in Pakistan and China
2. Wild Fire in Russia and Portugal
3. Flood in Australia
The consequences are in speculation on food crisis

Way of overcome this situation:
Exploitation of high yield
Quality grain
Shorter maturity
Biotic stress tolerance
Abiotic stress tolerance
Salinity
Submergence
Cold tolerance
High temperature
Drought

Rice production is increase in Bangladesh from 10 million metric ton to 25 million metric ton now. However, there is no reason to be complacent. The population of Bangladesh is still growing by two million every year and may increase by another 30 million over the next 20 years. Thus, Bangladesh will require about 27.26 million tons of rice for the year 2020.
Conclusion

Additional one grain may be make difference

.
Short duration modern variety rice should be introduce where local variety is cultivated. Need to cultivation of stress tolerant rice to combat the adverse effect of climate change: -Submergence -Drought -Salt Replacement of the present varieties by superior inbred, hybrid and super high yielding varieties
