In this study, the Chinese unique Free Air CO2 Enrichment FACE, 200 μmol·mol-1 higher than ambient AMB research platform was used to investigate the effects of FACE on grain yield formation of three-line indica hybrid rice cultivar Shanyou 63 under two levels of N input:Low(LN, 125 kg·hm-2)and normal N(NN, 250 kg·hm-2)in 2004—2006.

In this study, the Chinese unique Free Air CO2 Enrichment [FACE, 200 μmol·mol-1 higher than ambient CO2 concentration(AMB)] research platform was used to investigate the effects of FACE on dry matter(DM)production and distribution of three-line indica hybrid rice cultivar Shanyou 63 under two levels of N such as Low(LN, 125 kg·hm-2)and normal N(NN, 250 kg·hm-2)in 2005 and 2006.

Genetic analysis of the growth stage in three-line indica hybrid rice;

Following NCⅡ design, developmental genetic behavior of plant height in three line indica hybrid rice was studied, using additive dominance developmental genetic models and the corresponding statistical methods.

Genetic studies were conducted on the number of spikelet per panicle (NSPP) and the culm traits in three line indica hybrid rice, by using genetic models for additive dominant additive×additive epistasis including genotype×enviroment (GE) interaction.

The grain quality of the existing three line indica hybrid rice was studied with widely used 6 A lines, 9 R lines and their 54 hybrids as the materials.

With three-line hybrid rice Shanyou 63 as control,the high-yield characteristecs of source and sink in two-line hybrid rice,Yangliangyou 6 was studied.
