Thirty-six lines and varieties for yield and grain quality characteristics were evaluated. Plot size was 3.6 x 2 m with 20 x 20 cm plant spacing. Afaa Mwanza and M38 had the highest grain yields, followed by IR46, IR36, M40, IR42 and IET2379; CR1005 and IR5 had the lowest. The materials tested differed significantly in grain length to breadth ratio: the highest ratio was for Faya Theresa (slender), and the lowest ratio for F46 (medium). Supa India had the longest grains (extra long) and Cross 10 the shortest (medium). Amylose content varied, 19-28%. Popular varieties in Tanzania - Afaa Mwanza, Faya Theresa, Supa India, and Kihogo Red - had intermediate amyloses, as do a number of the introduced varieties. It was not possible to separate high-amylose rices into those with soft and hard gel consistency because laboratory facilities are limited.
