１９８９～１９９５年应用系统选育、纯化去杂和加代繁殖等育种方法，培育出紫稻新品系华黑０１、华黑０２．其稻谷平均产量分别为７３４５．５±４６９．５ｋｇ／ｈｍ２，６８２８．０±２７６．０ｋｇ／ｈｍ２；稻米蛋白质含量分别为１３．４１±０．３７％、１３．１５±０．５４％．８种必需氨基酸中有５～６种超过ＦＡＤ／ＷＨＯ建议的理想蛋白质标准．具较好的口感和营养品质
From 1989 to 1995, breeding methods of system selection, purification and impurity removal and additive reproduction were used to cultivate new purple rice lines Hua-hai 01 and Hua-hai 02. The average yield of rice was 7345.5 ± 469.5kg / hm2 and 6828.0 ± 276.0kg / hm2, respectively. The protein content of rice was 13.41 ± 0.37% and 13.15 ± 0.54% respectively. Five of the eight essential amino acids exceed the ideal protein standards recommended by FAD / WHO. With better taste and nutritional quality
