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

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.

Zhunliangyou 608 is a new indica two-line hybrid late rice combination that was bred by Hunan Longping Industry Co.

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.
