SCOPE
Rice is one of the most important crop in the world. The concept of shoot
ideotype in rice has partly been successful to use for breeding high-yielding
cultivars. Can the ideotype of root system, on the other hand, contribute
for yield? The purpose of the symposium is provide a forum for accelerating
our understanding of rice root system. Invited speakers will review important
information about structure and function of root system with reference
to genetic and ecological aspects, point out key deficiencies in our knowledge,
and suggest view- points leading us to new perspective.

Speakers
Craig A. Beyrouty:
University of Arkansas, USA
Soil chemist, crop ecologist. Studies environmental and management
influences on root growth and nutrient uptake of field grown crops. Root
dynamics of lowland irrigated rice is the present research topic.
Jiro Harada:
Saga University, Japan
Crop botanist and ecologist. Role of root systems for the growth and
yield of rice plants is one of main interests. How to control the development
of root systems is present research topic.
Jin Chul Shin:
National Crop Experimental Station, Korea
Crop physiologist, modeller. Experience of rice field experiments for
16 years. Interesting present topic is the influence of rooting pattern
on seedling establishment in direct seeded rice.
Len J. Wade:
International Rice Research Institute (IRRI), Philippines
Agronomist/crop physiologist. 22 years experience in rainfed agricultural
research. Interests include root traits for drought resistance, GxE interaction
and selection, nutrient x water interaction, establishment and seedling
vigour, and crop simulation and risk analysis.
