Asia I n 1989, Asia produced 449.3 of the world’s 492.1 million t of rough rice (FAO 1990b). Corresponding world rough rice consumption in 1986-88 was 418.7 million t, of which Asia consumed 380.2 million t. Asia produces and consumes more than 90% of all rice. Asia’s per capita milled rice supply in 1986-88 was 85 kg/yr (FAO 1990a). Bangladesh A nnual rough rice production was 25.5 million t in 1989 (FAO 1990b). Annual milled rice per capita consumption was 141 kg in 1979-81 (FAO 1984), 137 kg in 1986-88 (FAO 1990a, IRRI 1991), and 154 kg in 1988 (Duff 1991). Important varieties by district based on grain quality according to N.H. Choudhury (Bangladesh Rice Research Institute, 1990, pers. commun.) are Rajshahi—Jhingasail, Rajasail, and Indrasail (excellent); Bogra—White Biroi (very good), Purbachi (good); Dinajpur—Kataribhog (excellent); Khulna—Patnai (very good), Bhaital (good); Faridpur—Aman (good); Chittagong—Pajam (very good); Sylhet—Tepi boro (very good); Mymensingh—Red Biroi and Bashful (excellent); Dhaka—Kataribhog, Nizersail, and Red Biroi (excellent), Pajam (Mahsuri) and Jamir (very good), and Irrisail (IR20) (good). A consumer demand study found that the retail market price for parboiled rice in four districts correlated positively with length-width ratio and volume expansion, and negatively with 1000-grain weight and moisture content (Choudhury et al 1991). Market parboiled samples of Kalaribhog had 27-28% AC and Pajam had 27-29% AC (RCMD 1987, 1989). Retail market price for raw rice correlated positively with gel consistency values and negatively with percent brokens and cooking time.
