紫黑米的营养价值和药用功能早已被人们所认识,近年来,特种米的育种相继展开。1987年,我们从国际著名优质米Basmati 370体细胞无性系变异后代中发现了黑米突变体,经5代连续选育于1990年育成“黑珍米”,本文将其特征及成分与亲本作了初步比较。1 材料和方法以籼稻Basmati 370的成熟胚为起始材料,将脱壳的种子在75%酒精中浸泡1min,放入0.1%升汞溶液中灭菌20min后,用无菌水冲洗3～5次,再放入三角瓶中,每个三角瓶放100粒种子,振荡培养1～2d,当种胚萌动露白时接种在含2,4-D 2 mg/L和6-BA 2mg/L的N6固体诱导培养基上暗培养,当萌动幼胚 Purple black rice nutritional value and medicinal functions have long been known, in recent years, special rice breeding have started. In 1987, we identified black rice mutants from the offspring of somatic clones of the internationally renowned high quality Basmati 370 so that after breeding for five generations in 1990, they were bred as “black rice”. In this paper, A preliminary comparison. MATERIALS AND METHODS Mature embryos of Indica Basmati 370 were used as starting materials. The unhulled seeds were soaked in 75% alcohol for 1 min and sterilized for 20 min in 0.1% mercuric chloride solution. After washing with sterile water for 3-5 min, Times, and then placed in a triangular flask, put 100 seeds per flask, shake culture 1 ~ 2d, when the seed germination dew white when inoculated with 2,4-D 2 mg / L and 6-BA 2mg / L N6 solid induction medium dark culture, when germination immature embryos
