2Worlds rice scenario
Global Rice Production Increase Needed to Meet
Demand by 2035

3Rice in Asia
- Asia produces and consumes 80 of worlds rice
- Rice provides the largest of calories for human
diets in Asia
4Rice Scenario in India
- Staple food for two thirds of Indians, holds key
for food security (43) - Occupies 44 m.ha (22 of cropped area)
- Annual production gt100.0 m.t.
- Contributes 25 to Agril. GDP
- Earns a foreign exchange of Rs. gt35000 crore
- Rice is LIFE to Indians
India Vision 2020
- Vision envisages the target for 2020 as163 Mio
Mt ( Milled Rice ) - At the existing growth rate of 1.34 pa, India
can achieve rice production of 106 Mio Mt by 2020
Additional yield of hybrid rice at 1.5 Mt/ ha can
help to bridge the gap

(fertile) F2 F3 - F8 Testing Variety-Savitri
- Hybrid rice is the F1 offspring of a cross
between two genetically dissimilar parents. - The F1 hybrid is heterozygous and segregates in
the next generation. - The F1 seed has to be produced every year and
framers should not save their own seed to raise
the next crop. - Hybrid rice has higher yield potential due to the
phenomenon of heterosis.

7Hybrid Rice Key to Food Security
Yield advantage of hybrids (15-20) over varieties
- Globally more than 80 of hybrid rice is grown
in China - gt 65 production from about 55 hybrid rice area
in China - Fast expansion out-side specifically in Vietnam,
India Bangladesh
Tremendous opportunity and scope of further
expansion of hybrid rice technology
8Hybrid Rice is Growing Globally
2 million ha of hybrid rice added in rice
production in the last 4 years (10.2 increase),
outside China
9The Need of Hybrid Rice
- Rapidly increasing population
- Plateuing yield trend of HYVs
- Requirement of 122.1 m.t. rice by 2020
- At existing growth rate (1.34 pa), we can
achieve only 106 mt.
- Declining resources (Land, water)
- Unavailability of Labor
Hybrid Rice is one of the practically feasible
and readily adoptable options to enhance
productivity of rice vertically.
At additional yield of hybrid rice at 1.5 t/ha
can bridge the gap.

39Major constraints
- Marginal heterosis - unattractive for commercial
exploitation - Narrow genetic base a major concern
- Limited choice of hybrids for unfavourable
ecologies - Susceptibility of parental lines to major pests
and diseases - Meeting grain quality requirements to satisfy
diversified consumer preferences. - No strong institutional mechanism for production
and supply of seed of public sector bred hybrids. - Continued Trust Deficit between public and
private sector institutions in exchange of
knowledge and material. - No uniform subsidy component on hybrid seed cost,
which varies from State to State (0 to 100) - The condition that notified hybrids alone are
entitled for subsidy on seed cost, restricts
adoption of many good truthfully labelled hybrids
from the private sector - Lack of focused extension strategy for
popularization of new hybrids of promise. - Price discrimination against hybrids because of
apprehended low percentage head rice recovery. - Number of breeders engaged in hybrid breeding
especially in the public sector, is too low
40Future Research Strategies
- Developing hybrids with acceptable grain quality
- Developing long duration hybrids for shallow
lowlands and coastal areas - Development of hybrids for less water and saline
conditions - Enhancing magnitude of heterosis
- Incorporating resistance to major pests and
diseases. - Refining seed production package to reduce seed
cost - Intensifying transfer of technology efforts
41Strategies for expansion of hybrid rice area
- Popularizing hybrids throughout the state by
organizing minikits and identifying suitable
hybrids for different regions. - Better linkages among state departments, SAUs and
Institutes to conduct extensive FLDs at multiple
locations in each state. - Identifying suitable areas for HR seed
production. - Encouraging farmers to take-up hybrid seed
production. - Imparting training in HR cultivation and seed
production to farmers / extension personnel. - Creating proper awareness among farmers and
removing misconceptions about HR. -
42Strategies for expansion of hybrid rice area
- Arranging buy back of HR seed produced by
farmers. - Govt. subsidy in the initial stages to encourage
HR cultivation - Hybrid rice should be extended to stress
situations like shallow lowlands, saline/alkaline
tracts and boro areas where the hybrids have
proved to perform extremely well. - Public-private partnership should be further
strengthened to make the hybrid rice technology
more popular with the farmers. - Research front higher heterosis, better seed
producibility, two line system, parental improved
for higher stress tolerance, region specific
grain and cooking quality
