Abstract:

Te-Shan-Ai No. 2 (TSA), a high-yielding rice variety with wide adaptability, was developed by researchers at the Rice Research Institute, Guangdong Academy of Agricultural Sciences. It was released for cultivation in China in June 1996.

 

In the 1990-91 regional tests in southern China, the mean grain yield of TSA was 8.6 t ha-1, 14%) more than the local check and 5% more than the hybrid check. In the 1990-93 regional tests in Guangdong and Guizhou provinces, the mean grain yield was 6.9 t ha-1 , 14%) more than the local check in double-cropped areas; mean grain yield was 8.4 t ha-1,  3%)  more than the local check in single-cropped areas (Table 1). TSA was registered in March 1992 and July 1995 by the Guangdong and Guizhou Crop Variety Evaluation committees, respectively.
