The contents of protein, lysine and amylose, and MDH activity in three sorts of japonicatype hybrid rice-Bayou 161, Hanyou 195 and Hanyou 356 selected recently were analysed and compared with the japoniot-type hybrid rice-Hanyou 1027 planted on a large scale now. The results indicated: (1 )The amylose content of Hanyou 195 rice was lower than the content of Hanyou 1027 rice;and the relative content of lysine of the Hanyou 195 was hisher than the content of Hanyou 1027 rice. (2) The protein content of Bayou 161 riCe was 11. 1 % higher than the content nof Hanyou 1027 rice. (3)The protein content of Hanyou 356 rice was 5. 5% hasher than the content of Hanyou 1027 rice There was a possibility that the yield of Hanyou 356 rice was hasher than the yield of Hanyou 1027 rice.
