Biological Characteristics and Nutrition of New Colored Rice Lines in Central Vietnam

Background: Colored rice (Oryza sativa L.) is considered a nutritious food source than white rice and is becoming increasingly popular worldwide . At present, there have not been many studies of colored rice in Vietnam. The aim of this study to selecting colored rice varieties with short duration, high nutrition, good yield and the ability to be cultivated under intensive farming conditions in Binh Dinh province, Central region of Vietnam. Methods: The five new colored rice lines, namely BÐ.1, BÐ.2, BÐ.3, BÐ.4 and BÐ.5 and ANS1 variety as control were used in this study. The experiment was conducted in two seasons (2023 and 2024), completely randomized block design (RCBD) was employed with three replications. Morphological characteristics, yield and quality parameters were measured according to the standards in plant research. Result: From our research, we selected two promising lines, BÐ.1 and BÐ.4, which recordedyield from 64.57 to 73.47 quintals/ha in both seasons, anthocyanin content ranged from 27.83 to 35.79 mg/100g and iron content ranged from 23.89 to 23.82 mg/kg, respectively. It is recommended to continue developing these lines on a larger scale and to study some suitable technical measures for rice cultivation.
