    Abstract

    Sheath blight (ShB) is one of the important diseases in rice. This disease is caused by Rhizotonia solani Kuhn which can lead to decrease crop loses up to 80%. So far, the disease however is paid poorly attention by the farmers due to by the lack of information about the control techniques.. Therefore, the development of practical control being simply understood by the farmers such as the use of resistant varieties is needed to be done. The use of local variety resistant plant is interested to develop because it is easy to obtain and the durable resistance. At least amount of 12 rice local varieties have been collected being possible that one or more of one is/ are resistant to sheath blight. This study aimed to evaluate the resistance of 12 rice local varieties. The varieties were Slegreng Wonogiri, Rojolele, Mentik Wangi, Rojopusur, Rati Rahayu, Srikiti, Padi Hitam, Beras Merah Klaten, Rojopusur, Mentik Susu, Padi Merah Karanganyar, Sumatra, and Pandan Wangi compared with superior varieties namely IR64S, IR64PP and Inpari13. The experiment was conducted in Durenan Hamlet, Joho Village, Mojolaban District of Sukoharjo. The treatments were arranged by Randomized Completely Block Design (RCBD) with three replications. Each variety was grown on paddy field at 3x3m2 with spacing 0,2x0,2m. The observed variables were disease incidence, disease severity, infection rates, area under the disease progress curve (AUDPC), area of blight, sclerotia number, and crop yields. The results showed that Padi Hitam could be considered as the most tolerant varieties in the field compared to both the other one and superior varieties. The variety performed the lowest disease intensity and higher yield than the others. Keywords : resistance, Padi Hitam, disease intensity, susceptibility
