Molecular markers were used to map and characterize quantitative trait loci (QTLs) for panicle number per plant and other traits of agronomic importance in an inter-subspecific cross population of rice. The parents of the cross were a Tongil-type cultivar

“Surabyeo” is a new japonica rice cultivar developed from a backcrossed combination between the F1 of “Suweon 345/ Kanto PL4” and “Suweon 345” of lodging tolerant, semi-dwarf, high-quality rice line by the rice breeding team of National Crop Experiment St

“Saechucheongbyeo” is a new japonica multiline for blast resistance, which was composed of equal proportions in seed weight of three near-isogenic lines of two combinations. The recurrent parent, “Chucheongbyeo”, was a high-quality rice cultivar with susc

Anseongbyeo is a japonicaseed weight of three near-isogenic lines of blast resistance. The recurrent parent, Suweon345, was a high-quality and semi-dwarf rice cultivar with susceptability to neck blast. The blast-resistance donors for each liens were SR12

Diversity and relatedness of 64 rice accessions were evaluated using 85 simple sequence repeats (SSRs) markers. These64 accessions represent a set of international and Korean blast diferential cultivars, a set of blast monogenic lines, donors of blastresi

Molecular markers were used to map and characterize quantitative trait loci (QTLs) for traits related to cold tolerance in an intrasubspecif ic backcross population of r ice. The parents of the cross were a cold susceptible Tongil-type cultivar 'Milyang23

Through earlier breeding efforts, portions of the genome of the wild species Oryza grandiglumis (2n=48) have been introgressed into the rice cultivar, Hwaseongbyeo (Oryza sativa spp. japonica). Hwaseongbyeo was used as recurrent parent and O. grandiglumis

Wild rices are an important source of useful genes for resistance to diseases, insect pests, tolerance for abiotic stresses and yield increase. O. minuta (BBCC), a tetraploid wild rice having 48 chromosomes, was used for the cross with japonica rices. Fer

Wild rices are an important source of useful genes for resistance to diseases, insect pests, tolerance to abiotic stresses and yield increase. Interspecific hybrids were successfully produced between ten accessions of O. minuta (2n=48, BBCC) and O. sativa

Resistance genes to the blast pathogen (Pyricularia grisea Sacc.) were mapped using a recombinant inbred population consisting of 231 lines derived from a cross between the japonica parents, ‘Suwon365’ and Chucheongbyeo. Phenotypic analysis showed that Su

Diversity of 80 japonica rice cultivars was evaluated using 65 microsatellite or simple sequence repeat (SSRs) markers. Sixty-five microsatellite markers representing 65 loci in the rice genome detected polymorphisms among the 80 cultivars and revealed 28
