在毛主席革命路线指引下,在农业学大寨、普及大寨县的群众运动中,我们对杂交水稻的三系及杂种一代的生化研究,取得一定的进展。在前两年对广选三号不育系、南优二号等花药中自由氨基酸初步分析的基础上,一九七六年又对广选三号等几个不育系、保持系、恢复系及杂种一代的花药中自由氨基酸进行了研究。前两年的研究结果表明,不育系的花药中脯氨酸的含量很少,而恢复系及杂种一代则含量较高。为了摸索脯 Under the guidance of Chairman Mao’s revolutionary line, we made some progress in the study of the biochemistry of the three-line and hybrid generations of hybrid rice in Dazhai in Agriculture and Popularization of Dazhai. On the basis of the preliminary analysis of the free amino acids in the anther of the No. 3 CMS and No. 2 in the first two years of Guangzhou, Lines and hybrids of anthers free amino acids were studied. The results of the previous two years showed that there was little proline in the anther of the sterile lines, while the restoring lines and the hybrids had higher content of proline.
