Technical Abstract: Seventy-five accessions of international germplasm of rice were classified into three maturity groups and evaluated for grain yield, milling yield, grain shape and grain quality in Stuttgart, Arkansas in 2001. These accessions had been identified in 1999 and 2000 quarantine programs as having high yield potential. There were 47 accessions from Ivory Coast, including 2 derivatives of Oryza sativa/O. glaberrima and 30 accessions of tropical Oryza crosses (Tox), 3 accessions from Bangladesh, 4 from Brazil, 10 from Egypt, 1 from Japan, 5 from Korea and 5 from Philippines. Bogra from Bangladesh in early group 1, GZ-1368-5-4 of Egypt in intermediate group 2 and Tox 3717-25-3-3-2 from Ivory Coast in late group 3 had both grain and milling yields comparable with or higher than LaGrue. The 2 derivatives in group 1 yielded less than US cultivars due to lack of uniformity, but 1 derivative had comparable milling yield. Egyptian Jasmin in group 2 had intermediate yield and good head rice. Of the 75 accessions, variation for amylose ranged from 16.5 to 27.5%; for protein from 7.7 to 11.0%; for length of brown rice from 5.3 to 7.9 mm; for width of brown rice from 2.0 to 2.9 mm; for length/width ratio from 1.9 to 3.7; for 1000 brown rice kernel weight from 16.2 to 24.6 g; and for 1000 rough rice kernel weight from 18.9 to 28.9 g.
