Research progresses in distribution and enrichment of GABA in rice,mutation breeding for giant embryo rice enriched with GABA and their genetic control and expression,and functional rice products enriched with GABA were reviewed in the .

Using 72 RFLP markers distributed on 12 chromosomes together with 8 restriction enzymes (EcoRⅠ, EcoRⅤ, Hind Ⅲ, DraⅠ, EcoRⅠ,ScaⅠ, BamHⅠ and BglⅡ), the RFLPs among a rice variety, Kinmaze and its giant embryo and sugary endosperm mutants derived from MNU treatment were studied.

Giant embryo rice is a kind of characteristic rice with gi.

Relationship between rice embryo weight and grain shape characters in giant embryo rice;

In order to elucidate the development of embryonic characteristics of giant embryo rice TgeB(Oryza sativa L.

The grain-filling characteristics of two giant embryo rice cultivars and their corresponding original types were studied.

Development and Research of Special Type Giant-embryo CMS Line 813geA

The results indicated that the seed germination rate and germination index were low,seed activity was weak, the seed was not able to bear storage and the seedlings growing was bad of Japonica giant embryo rice with storage more than two years,but the seed activity was strong,and seedlings growing was very good of new harvest seeds.

[Objective]The study aimed to explore the rational cultivation mode that was in favor of the growth of flag leaf in Japonica giant embryo rice.

In order to study the germination and the ability of preharvest sprouting resistance of different mature degrees of Japonica giant embryo rice seeds,the seed and panicle germination experiment of different days after flowering of Japonica Xi-giant embryo-1 was conducted,the local variety of japonica rice Hexi-22-2 as control.
