| Abstract |
Rice blast has become a problematic situation for rice cultivation worldwide. Blast disease is caused by a fungus Magnaporthe grisea (Pyricularia oryzae), essentially diminished yield and value of rice grains. This study was conducted to evaluate for resistance of the rice germplasm against rice blast disease under natural infection in field condition, to give faster screening for rice blast resistance as a forerunner in a breeding system. A total of 347 Thai indigenous lowland rice germplasm with 14 check varieties, were screened under a natural infection in blast hot spots field. The screening was conducted at two locations that have a history of high incidence of blast disease occurrence. A completely randomized design with 3 replications was laid out, blast disease scoring of standard evaluation system (SES) 0-9 method of IRRI were recorded. The finding revealed that two third of indigenous lowland rice accessions were classified as blast resistant in both experimental years with score lower than 2.00. Additionally, the top ten selected indigenous lowland rice accessions including LLR276, LLR397, LLR054, LLR425, LLR055, LLR057, LLR253, LLR334, LLR363, and LLR258 also showed resistant ability under upland short row condition, that indicated that those accessions providing an emerging alternate sources of blast resistance varieties in Thailand, for future rice breeding programs. |
