田间试验表明,供试9个杂交水稻品种对黑条矮缩病的抗性可初步分为中抗、中感、高感3个类型。其中安两优318、粤优54、富优2号为中抗,并以安两优318抗性为最强,丰产性能也好。而协优963、K优818为中感;甬优6号、甬优5号、加优99,以及协优9308为高感组合。 Field experiments showed that the resistance of 9 hybrid rice varieties to black-streaked dwarfism could be divided into three types: moderate resistance, moderate sensitivity and high sensitivity. Among them, Anliangyou 318, Yueyou 54 and Fuyou 2 were moderately resistant, and the resistance to Anliangyou 318 was strongest and the yield was good. While Xieyou 963 and K You 818 were in the sense; Yongyou No. 6, Yongyou No. 5, Jiayou 99, and Xieyou 9308 were highly sensitive.
