Hybrid Rice Technology for Food Security in the
World

• L.P.Yuan
• The World Food Prize International Symposium
• October 15, 2004

2
Foreword

• Population in the World
• Current over 6 billion
• 2030 about 8 billion
• Arable Land
• Annual loss 10 to 35 million ha

3
Foreword

• It is expected that 60 more rice should
  produced in 2030 than in 1995
• Enhancing the yield per unit land area is the
  only way to solve food shortage problem
• Rice still has great yield potential
• Using hybrid vigor is one of the best ways

4
Hybrid Rice in China

• Yearly planting area 15 million ha
• Average yield of hybrid rice 7.0t/ha
• Average yield of inbred rice 5.6t/ha
• Yield advantage over 20
• 60 million more people can be fed each year

Super Hybrid Rice
11
Super Rice Program by Chinese Ministry of
Agriculture

• Phase I 1996-2000
• 10.5 t/ha ( on large scale demonstration)
• Phase II 2001-2005
• 12.0 t/ha (on large scale demonstration)

12
Achievements and Progress
13

• Several pioneer super hybrid rice varieties had
  been developed by 2000, which attained
  phase?yield standard.
• The average yield is around 9 t/ha in large scale
  commercial production (1.2-1.5 million ha) in
  recent years.
• Yield advantage 20 over traditional hybrid rice

Good Progress Has Been Made in Developing
Phase II Super Hybrids
19
Above 12t/ha in an area of 8 ha at Longshan
county in 2002
20
Above 12t/ha at 5 locations in 2003

Good Grain Quality
22
Prospects

• By reaching the yield target of phase ?,
  2.25 tons/ha more rice can be produced by super
  hybrid rice, which will increase 30 million tons
  of grains yearly when it is commercialized up to
  13 m.ha.

23
Hybrid Rice outside China

• Hybrid rice commercialized in Vietnam and India
• Vietnam
• 600,000 ha in 2003
• Yield 6.3t/ha against 4.5 t/ha for inbred
• Second largest rice export country

24
Hybrid Rice outside China

• Good progress has been made in

• Philippines
• Bangladesh
• Indonesia
• Pakistan
• Ecuador
• Guinea
• USA

25
Hybrid Rice in Philippines

• SL-8 8.5t/ha, 3000 ha in 2003

26
1 million ha to be planted by 2007

Conclusion

• Hybrid rice will play a key role in ensuring food
  security worldwide in the new century.
• If 50 of rice paddy covered by rice hybrids in
  the world, rice production could be increased by
  another 150 million tons.
• 400 million more people can be fed.

28

• For the benefit of the people in the whole world,
  our Center and I are well prepared to help other
  countries to develop hybrid rice
