Wheat variety ‘Raj 848’ was genetically analysed against stem rust race21 and 40. F1, F2 and F3 seedlings were tested against both the races. It was found that ‘Raj 848’ carries Sr11 plus an additional, new, dominant gene. The latter conditions (2 =) reaction to race 40 only and is tentatively designated as Sr848. Sr11 imparts hypersensitive reaction to races 21 and 40.
