Abstract

Rice crop is one of the major food commodities in Indonesian. However, rice production can decrease due to the blast attack caused by the fungus Pyricularia oryzae. Efforts to reduce blast disease can be done by cultivating local red rice. Red rice has high nutritional and antioxidant content and has resistance to blast disease. The aim of research was to determine the level of endurance of 10 lines red rice against blast disease attack and to obtain which rice line resistant to blast disease. The research was conducted from January to March 2020 in the greenhouse of Muara experiment station of Indonesian Center for Rice Research, Bogor, West Java. The research used Factorial Randomized Block Design (FRBD) with two factors. The first factor was 10 lines of red rice, 4 elders and 2 control varieties. Second factor are 4 race blasts (033,073,133 dan 173). The selection method is adjusted to the standard of Interational Rice Blast Nursery (IRBN). The results showed 10 red rice lines were resistant to race blast 033, 9 red rice lines were resistant to race 073, and 7 red rice lines resistant to race (133 and 173). The red rice line; 19i-06-09-23-27, 19i-06-09-23-3, 19i-06-30-17-17 have the highest resistance. The resistance level of these three line was not differed significantly with Situ Patenggang variety (resistant control) and Inpago 8 variety which were the highest resistance to blast disease
