| Abstract: | The study results of panicle and grains distribution,characters of canopy,accumulation and partition of dry matters in the upper reaches of Yangtze River were reported.The ideas and methods for breeding super rice such as'indicalinous type','big panicle big grain','thick culms wall V type leaf','the dynamic plant type with drooping in earlier stage and erect in later stage','reasonable division of traits in sterile lines and restore lines' were proposed and the main progress for creating the super rice materials and breeding the excellent cross combinations were also reported. |
