THE BREEDING OF SUBSPECIFIC HEAVY EAR HYBRID RICE-EXPLORATION ABOUT SUPER-HIGH YIELD BREEDING OF HYBRID RICE
Zhou Kaida et al(Rice Research Institute, Sidhuan Agricultural University/Wengjiang, Sichuan, China 611130)
The super-high yield breeding methed of subspecific keavy ear typic combination and its key technique,ere proposed via inspecting relationship between funetional leaves area and ear or graln weight. In nearly 10 years, a set of large spikelet sterile lines and,ide-compatibitity restorer lines haye been bred, and some heavy ear typic hybrid combinations suck as Ⅱ you6078 et al were breed. Trials of 5 years indicated that the Ⅱ you678 could increase more than 15% yield to skanyou63 in the condition of space cropping.
