Abstract:
Thirteen advanced generation rice breeding lines were evaluated along with two checks so as to ascertain yield, yield attributing and quality traits possessed by the lines. The experiment was conducted in Randomized Block Design (RBD) with three replications having a plot size of 15m². Analysis of variance depicted sufficient variation among the lines indicating that these lines are diverse from each other with respect to yield, yield attributing and quality traits. As regards yield among the thirteen advanced generation lines under evaluation SJR 82-2-3 was found to exhibit highest grain yield of 45.50 q/ha followed by the lines SJR 92-2-2 and SJR 80-1-1 exhibiting 43.30 q/ha and 41.90 q/ha respectively. With respect to per cent superiority over the checks it was found that SJR 82-2-3 exhibited 34.61 per cent yield superiority over Basmati 370 and 29.50 per cent over Basmati 564 followed by SJR 92-2-2 and SJR 80-1-1 exhibiting 28.10, 28.93 and 23.96 and 19.26 per cent yield superiority over the checks respectively. In addition disease and insect pest reaction revealed that all these three identified lines were found to be moderately resistant to brown spot, leaf blast, Bacterial leaf blight and stem borer under field conditions.
