Abstract
One of the important diseases in rice (Oryza sativa L.) is the blast disease (Pyricularia oryzae), which greatly affects the quality and quantity of rice production. This study aimed to determine the differences in the development of blast disease, as well as to obtain local upland rice cultivars in Southeast Sulawesi which had the lowest development of blast disease, in two different planting __cpLocations. This research was conducted in Lamomea Village, Konda District, Konawe Selatan Regency and Kambu Village, Kendari City. The research was arranged in a Complete Randomized Block Design (CRBD) consisting of 10 local upland rice cultivars of Southeast Sulawesi, namely: Tinangge (G1), Konkep (G2), Loiyo putih (G3), Waburi-buri (G4), Momea (G5), Wangkariri (G6), Bombana (G7), Wakawondu (G8), Wagamba (G9) and Bakala (G10), which were repeated 3 times. Six plant samples were taken from each plot. The variable observed was the development of blast disease, which consisted of disease severity, disease infection rate and disease progression curve. The results showed that from the planting __cpLocation in Lamomea Village, the cultivar with the lowest disease progression was Konkep cultivar (G2) with disease severity of 12.59%, infection rate of 2.37% and disease progression curve of 35.59%. For cropping in Kambu Village, the cultivar with the lowest disease progression, namely the Momea cultivar (G5) had the lowest disease severity at 33.33%, the infection rate was 6.52% and the disease progression curve was 80.78%, which was lower than the other cultivars. Results of the study showed that there was an opportunity to obtain local upland rice cultivars that were relatively resistant to blast disease.
