To meet the future demand for rice production, a national program on super rice breeding was established In China In 1996. The corresponding targets, breeding strategies and most significant advances are reviewed In this paper. New plant type models have been modified to adjust to various rice growing regions. In recognition of the Importance of applying parents with Intermediate subspecies differentiation In Increasing F1 yield, medium type parental lines were selected from populations derived from Inter-subspecies crosses with the assistance of DNA markers for subspecies differentiation. Results also indicate that a substantial increase of blomass Is the basis for further enhancement of the grain yield potential, and amelioration of leaf characteristics Is helpful In Increasing the photosynthetic rate. Thirty-four super hybrid rice varieties have been released commercially, growing In a total area of 13.5 million hm2 and producing 6.7 thousand million kg more rice In 1998-2005. Although remarkable progress has been made In super hybrid rice breeding In China, selections on the root system and Integration of more blotechnologlcal tools remain a great challenge.展开更多

Objects in both the pilot survey and the first year regular survey are included in the LAMOST DR1. The pilot survey started in October 2011 and ended in June 2012, and the data have been released to the public as the LAMOST Pilot Data Release in August 2012. The regular survey started in September 2012, and completed its first year of operation in June 2013. The LAMOST DR1 includes a total of 1202 plates containing 2 955 336 spectra, of which 1 790 879 spectra have observed signalto-noise ratio(SNR) ≥ 10. All data with SNR ≥ 2 are formally released as LAMOST DR1 under the LAMOST data policy. This data release contains a total of 2 204 696 spectra, of which 1 944 329 are stellar spectra, 12 082 are galaxy spectra and 5017 are quasars. The DR1 not only includes spectra, but also three stellar catalogs with measured parameters: late A,FGK-type stars with high quality spectra(1 061 918 entries), A-type stars(100 073 entries), and M-type stars(121 522 entries). This paper introduces the survey design, the observational and instrumental limitations, data reduction and analysis, and some caveats.
