Technical Abstract: In 1996, 213 rice accessions were introduced from China for enriching USDA rice germplasm collection. Evaluation for the Chinese germplasm on yield potential, disease resistances and grain quality was conducted in 2000 and 2001. Fifteen accessions yielded in excess of 10,130 kg/ha rough rice that compared with the rough rice yield of 7,560 kg/ha in the highest yielding check cultivar `LaGrue'. Accession `GP-2' had the highest rough rice yield of 11,693 kg/ha. Out of the 15, 14 accessions were rated 0 as highly resistant to blast, and 13 were rated 5 as moderately susceptible to sheath blight. Among the highly yielding germplasm, Taizhongxian 255 was medium grain type with amylose content of 14.6% which is same with the U.S. medium grain Bengal. Long grain R312 had an amylose content of 21.7% similar to the U.S. long grain `Wells'. These accessions have been entered in the USDA Rice Germplasm Collection between PI 614956 and P1 615217.
