Evaluation of grain quality and yield attributes traits in biofortified rice (oryza sativa l.) Lines

Abstract

An experiment was conducted for the ten rice lines developed by crosses between 2 parents Varalu having high iron and zinc content and NDR-359 have good yield in Randomized complete block design at student instructional farm kumarganj, Ayodhya during Kharif season 2023. Ten lines of rice were evaluated during 2023 on the basis of grain quality parameters and yield attributing traits with three replications. The maximum protein (mg/g) content (9.54) was observed in varalu and in NDR 2305 (9.09). Total starch content (78.71%) in NDR 359 and in developed line NDR 2302 (77.91%). The maximum iron and zinc content (ppm) was found in varalu (17.29 ppm, 26.76ppm) and in line NDR 2303 (17.04ppm), in NDR 2302 (25.33ppm) respectively. Phytic acid content high in lines NDR 2301(11.17µg/100ml). Maximum panicle length was recorded (24.83cm) in NDR 2305. Highest number of grains per panicle was recorded (128.33) in NDR 2302. Maximum test weight (g) was recorded (24.73) in NDR 2305. Maximum grain yield per plant was recorded (24.42g) in NDR 359 and (22.39g) in line NDR 2305.
