利用云南高秆大穗大粒品种“毫糯干相”与“IR_(29)”品种杂交育成了两个中矮秆、优质、大粒的水稻新品系—“云香糯一号”和“云香糯25号”。在云南、广西、四川等省的一些地区示范种植表观株型好、产量高、米质好、抗病力强。这两个新品系的育成,表明中矮秆、中穗大粒、优质、抗病性强等性状可以结合在一个品系中;并证实了云南高秆大穗大粒稻种资源在水稻高产育种中具有重要利用价值。 Two new lines of middle-dwarf, high-quality and large-grain rice - “Yunxiangnuo No.1” and “Yunxiangnuo No.1” were bred by the hybridization of “Qiannuo Dry Phase” and “IR_ (29) Glutinous 25 ”. In Yunnan, Guangxi, Sichuan and other provinces in some parts of the apparent planting plant model is good, high yield, good quality, strong resistance to disease. The breeding of these two new lines showed that the characters of middle dwarf, middle ear big grain, high quality and strong disease resistance could be combined in one line. And it was confirmed that the resources of high stalk big ear and large grain of Yunnan had Important use value.
