海南岛乐东盆地黑米育种实践与展望

Breeding Practices and Perspectives of Black Rice in Ledong Basin of Hainan Province

黑米是全谷物食品,营养丰富,具有多种保健功能。在海南岛乐东盆地,笔者利用得天独厚的生态环境开展黑米育种研究。主要采用多重复合杂交,结合群体选择的技术路线,10余年来共审定了2个黑米新品种,并有多个品系参加区试。本文总结了黑米育种技术、品种特性及配套栽培技术,并对未来黑米育种的方向及花青素利用提出了建议。

Black rice is a kind of whole-grain cereal, which has abundant nutrients and many health benefits. In Ledong basin of Hainan Province, it has unique ecological environment for breeding black rice. Two main technical ways, such as multiple crossing and population selection have been carried out. In the past ten years, two black rice new varieties have been officially registered, and some breeding lines attended regional tests. The breeding techniques of black rice, variety characteristics and cultivation techniques were summarized, and new perspectives for future breeding of black rice and utilization of anthocyanin of black rice were also proposed.
