Abstract:

To identify some varieties with basmati background to be used as donors, the first International Fine Grain Aromatic Rice Observational Nursery (IRFAON), consisting of 33 entries including the international check Basmati 370 along with local check Pusa Basmati 1, was grown under normal cultural practices during the 1996 wet season. All the varieties were analyzed for 14 physicochemical characteristics at the Directorate of Rice Research, Hyderabad, using standard procedures. These characteristics involve grain size and shape, endosperm appearance, and milling and head rice recovery (HRR). Among the cooking and eating quality traits, water uptake (WU), volume expansion ratio (VER), kernel length after cooking (KLAC), elongation ratio (ER), gelatinization temperature (GT), and amylose (AC) content were studied.
