Studies on grain quality and 'soak n eat' traits of some Assam rice collections
A study was undertaken with 31 rice germplasm collected from various parts of Assam to identify rice genotypes with good grain quality and 'soak n eat' trait. Eighteen of these had short slender grains, , seven had long slender grains, and six had medium slender grains. The cultivar Hati dotia had the longest grain (6.55 mm) followed by Gandhi biroin (6.38 mm) and Nalburni (6.32 mm). Hati dotia also had the highest length:breadth ratio (4.2), kernel length after cooking (11.7 mm) and very good elongation ratio (1.9). Aghoni and Prachakua also showed more than 1.9 times grain elongation. The amylose content varied widely (4.35% to 26.35%). Other than Aghoni and Bhogali, two more germplasm namely, Nalbora and Asham Biroin exhibited the 'soak n eat' characteristic with soaking time of 80 minutes for each. Asham Biroin also exhibited very high hulling (80%), milling (69.5%) and head rice recovery (66%).
