In 14 selected rice samples, NSIC Rc 222 had high (14.70%) moisture content that lead to low grain or seed quality. Both PSB Rc 22 (77.0%) and M-19 (77.0%) of brown rice had good to premium milling recovery. Chalky grains of selected rice varieties within grade 1 to premium classification are Laon mahilab (5.0%), Vita rice (3%), Brown rice (3%), M-19 (2.0%), M-20 (1.0%), Matador long grain (1.0%) and Jasmine rice (0.0%). Rough rice had extra-long and slender classification whereas all of the milled rice and brown rice had long and slender classification. Rice varieties had high gelatinization temperatures are Iniput ibon, NSIC Rc 23, M1 14 DS, Sinandomeng, PSB Rc 22, NSIC Rc 122, M-19, M-20, Brown rice, and Laon mahilab however, NSIC Rc 240, Jasmine rice, Vita rice, and Matador long grain had low gelatinization temperature. Most of low gelatinization temperature rice had high amylose content, except for matador long grain whereas high gelatinization temperature rice had intermediate amylose content, low to intermediate, high amylose content and intermediate to high amylose content. Majority of the selected rice varieties had a value of 1.1 (50%) and 1.2 (50%) water uptake ratios (fresh) and most of staled water uptake ratio had a value of 1.2 (64%) and 1.1 (36%). Among the selected rice varieties, NSIC Rc 240 had high Instron hardness for staled (4.44) and fresh (6.99) than M-1 14 DS while PSB Rc 122 had lower RVA setback and consistency.

Keywords: brown rice, milled rice, gelatinization temperature, apparent amylose content, water uptake ratio, cooked rice hardness, RVA pasting viscosity.
