功能性水稻新品种品黑一号的选育及营养安全研究初报

摘要

该文较为系统地阐述了品黑一号的亲本来源、选育过程、特征特性、营养品质以及重金属含量安全等相关问题，其中4个样品中硒含量变幅在0.035～0.57mg/kg，平均为0.29mg/kg，达到富硒标准；铁含量超过检测低限15%以上；锌含量超过检测低限4倍以上。经过标准化生产的黑米重金属镉含量到达检测低限以下，低于国家标准4～5倍，达到有机标准。%The indica black glutinous rice variety Pinhei 1 was bred and could be used for producing functional rice products.In this paper,the origination of its parental lines,breeding procedure,agronomical and nutritional parame⁃ters was presented.The selenium content of the variety from four sources was among 0.035~0.57 mg/kg with a mean of 0.29 mg/kg,which reached the standard of selenium-fortification.Concentrations of iron and zinc were 15%and 4 times above the lowest detection limits,respectively.Following the standardized production procedures,the concen⁃tration of cadmium,a heavy metal pollutant,was under the lowest detection limit,which was 4-5 times lower than the national safety limitation.Such product could be considered organic.
