用目前较好的水稻籼型光温敏核不育系W6154_S和K_S-9配制的杂交水稻,其产量尚不及三系杂交稻广优青和汕优63,但其谷秆比值和颖花退化率均比三系杂交稻和常规稻品种有明显的优势,象W6154_S×特青这样的组合其主茎功能叶片开张角比较符合高产株型的要求。
The yield of hybrid rice prepared with the present indica type photo-thermo-sensitive genic male sterile lines W6154_S and K_S-9 was less than those of the three-line hybrid rice varieties Guangyouqing and Shanyou 63, but the grain stalk ratio and spikelet degeneration Compared with the three-line hybrid rice and the conventional rice varieties, the rate of the opening of the functional leaves of the main stem of W6154_S × Teqing was more in line with the requirements of the high-yielding plant type.
