| Outline of Final Research Achievements |
To feed future world population, adaptive cultivar against increasing atmospheric CO2, which increase photosynthesis, biomass and productivity, is an option to boost crop productivity. The purpose of this research is to identify alternative, cheap and reliable methodologies to screen responsive cultivars to future elevated CO2 without using CO2 fumigation facilities for crops, rice and soybean. Six hypotheses were tested, (1) low CO2 chamber method, (2) stomatal sensitivity method, (3) planting geometry method, (4) Finlay Wilkinson regression method, (5) Rural-Urban gradient method, (6) natural CO2 spring method. We concluded that (3) planting geometry method and (4) Finlay Wilkinson regression method can be used for alternative screening method without using CO2 fumigation facilities.
