A near-isogenic line CR1815, containing three introgressed segments on chromosomes 1, 7 and 9 from 0. rufipogon into the Oryza saliva cultivar Milyang23 background was developed based on MAS (marker aided selection) and backcrossing. The introgressed segm

Low temperature germination is one ofthe major determinants for stable stand establishment in the direct seeding method in temperate regions. Quantitative trait loci (QTLs) controlling low temperature germiability (LTG) and awn were confirmed in BC1F1 usi

Various mutants of specialty rice were derived from Ilpumbyeo, a high-quality japonica rice cultivar, through muta-tion breeding by MNU treatment on fertilized egg cells of rice spikelets. The selected mutants revealed glutinous, semi-glutinousfthem were

A recombinant inbred lines (RILs) consisting of 231 lines, derived from a japonica (Suweon365) and a japonica (Chu-cheongbyeo) rice, was used to investigate the genetic factors affecting cooking and eating quality of rice. Alkali digestion valueloci (QTLs

To ensure the durability of resistance to blast disease in high-quality japonica rice a long-term rice breeding project to develop a few blast-resistant multiline cultivars was carried out from 1987 to 1999. Seven resistance donors were selected based on
