高蛋白华03早籼新品系是在1978～1988年,应用花培、化诱生物技术结合常规杂交育种方法,以IR_8/二九青F_2代优穗为花培起始材料培育成的。华03比推广品种广陆矮4号早熟3～5天,广泛适应于北纬23.0～32.0°,东经107～120°范围的湖北、湖南、江西、广西等地。1985～1988在江西、湖北等地大田试种结果,平均亩产稻谷400公斤以上,比当地对照品种增产6～10%,并具有较好的适口性、精米率和营养品质。它的突出特点是稻米蛋白质含量特别高,五年先后经中国农科院测试分析中心等单位分析不同产地华03试种稻米样品,其蛋白质含量平均达糙米干重的13.72%,八种必需氨基酸有六种超过联合国粮农组织和世界卫生组织(FAO/WHO)1973年提出的理想蛋白质的标准。
The high-protein Hua-03 early-indica new line was cultivated from 1978 to 1988 by using the flower culture and the induced hybrid technology combined with the conventional hybrid breeding method. China 03 is more widely used in Hubei, Hunan, Jiangxi and Guangxi in the range of 23.0 ~ 32.0 ° north latitude and 107 ~ 120 ° east longitude than the popularized variety Guangluan 4. 1985 ~ 1988 In Jiangxi, Hubei and other places of field test results, the average yield of more than 400 kilograms of rice, than the local control varieties yield 6 ~ 10%, and has good palatability, milled rice rate and nutritional quality. Its prominent feature is the high protein content of rice, five years successively by the Chinese Academy of Agricultural Sciences Test Analysis Center and other units to analyze different regions of China 03 trial rice samples, the average protein content of brown rice, dry weight of 13.72%, eight essential amino acids There are six standards that exceed the ideal protein proposed by the UN Food and Agriculture Organization and the World Health Organization (FAO / WHO) in 1973.
