6. What We Would Like to Address
1) To evaluate plant performance under real field conditions. (G x E )
2) To evaluate gene technology for plant performance in different genetic
background under water-limited conditions. (G x G)
(1) Does gene technology work (2) Does gene technology works in commercial variety
in field conditions?

7. Our Challenges and Solutions
• Product concept (target environments)
• Field evaluation of crop performance under drought conditions
• Biosafety risk management for GM materials
• Gene effects in different genetic background
