Breeding and application of giant-embryo indica rice new line Liantangjupeihong.

The giant-embryo indica red rice new line Liantangjupeihong was bred through the hybridization between "91-308" and "Jupei No.1".The breeding process,variety characteristics and cultivation techniques of Liantangjupeihong were introduced in this paper.Liantangjupeihong has strong tillering ability,the growing duration of 112~114 days and the yield of about 4500 kg/hm2.This line is suited to be planted as double-cropping late rice in Gan-Fu plain and south-central hilly and mountainous areas of Jiangxi province.The rice of this line possesses the characteristics of giant embryo,red seed coat,rich content of γ-aminobutyric acid,iron and multiple essential amino acids,so this line can be comprehensively exploited and utilized as the raw material of making functional rice which is able to reduce blood pressure.
