Progress in ideotype breeding to increase rice yield potential

The ideotype approach has been used in breeding programs at the International Rice Research Institute (IRRI) and in China to improve rice yield potential. First-generation new plant type (NPT) lines developed from tropical japonica at IRRI did not yield well because of limited biomass production and poor grain filling. Progress has been made in second-generation NPT lines developed by crossing ...

Photosynthesis, grain yield, and nitrogen utilization in rice and wheat.

Rice (Oryza sativa) and wheat (Triticum aestivum) are the two most commercially important crops, accounting for more than 40% of global food production. They were domesticated in different climates and differ largely in their growth environments: Rice is tropically cultivated in hot, wet climates, whereas wheat tends to be grown in cooler temperate climates. However, both crops have been bred i...

The relationships between carbon isotope discrimination and photosynthesis and rice yield under shading

The measurement of carbon isotope discrimination (∆) provides an integrated insight into theresponse of plants to environmental change. To investigate the potential use of ∆ for identifyingshade tolerance in rice, five rice varieties were selected and artificially shaded (53% lightreduction) during the grain-filling period in 2010 and 2011, in Sichuan, China. Shadingtreatment had a significant ...

Coordinated regulation of photosynthesis in rice increases yield and tolerance to environmental stress

Plants capture solar energy and atmospheric carbon dioxide (CO2) through photosynthesis, which is the primary component of crop yield, and needs to be increased considerably to meet the growing global demand for food. Environmental stresses, which are increasing with climate change, adversely affect photosynthetic carbon metabolism (PCM) and limit yield of cereals such as rice (Oryza sativa) th...
