영문 초록

The purpose of this study was to detect and map quantitative trait loci(QTL) related to rice seedling growth at low temperature. The F₂ populations of 94 plants was obtained from a cross between a coldsusceptible indica cultivar ‘Dular’ and a cold-tolerant japonica cultivar ‘Toyohatamochi’. A molecular genetic map was constructed using random amplified polymorphic DNA (RAPD) markers and QTL associated with the cold tolerance of rice seedling at 18℃ was analyzed using MAPL-MQTL computer program. Analysis of RAPD patterns regarding to cold tolerance in F₂ population of Dular/Toyohatamochi cross indicated that two RAPD markers 20 and 29 were located with 21 cM apart on chromosome No. 5 and QTL related to seedling growth at 18℃ was closely associated with these DNA markers. The association of the RAPD markers on chromosome 5 with the seedling growth at 18℃ was observed in a separate analysis using F₃ plants of the cold-susceptible indica cultivar ‘K-sen 4’ and the cold-tolerant javanica cultivar ‘Silewah’.
