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
This study was carried out to develop a prom ising japonica rice variety resistant to brown planthopper(Bph) through marker-assisted selection(MAS) and backcross breeding methods. 'Milyang 64' which is known as resistant japonica variety to Bph used as a
Regional Adaptability Test (RAT) was conducted to select promising breeding lines of rice for cultivation in specif ic regions. Analysis of genotype (G) and genotype by environment (G×E) interaction observed in RAT was carried out to test their adaptabili
Areumbyeo', a second generation Tongil-type rice variety (Oryza sativa L.), has been developed at National Yeongnam Agricultural Experiment Station (NYAES) from 1983 to 1999 and released in 2000. A single cross between YR3299-34-2-2 and Suweon 318 (was co
Nonghobyeo', was derived from a mutant of Milyang 95, by pure line selection method, which was developed from the single cross between Chukei 1016 and Milyang 79, by the rice breeding team of National Yeongnam Agricultural Experiment Station (NYAES) in 19
Mananbyeo was developed from a three way cross ilyang110/Yeongdeog7//Milyang110 in 1999. It has short growing duration about 71 days from seeding to heading and short culm length of 75 cm. It has almost similar number of panicles per hill , spikelets per
Sujinbyeo', a new mid-late maturing japonica rice variety (Oryza sativa L.), was developed by the rice breeding team of National Yeongnam Agricultural Experiment Station (NYAES) in 1999 and released in 2000. This variety originated from a three way cross
Korean Rice Breeding Information Management System (KRBIMS) is a database and its management system that provides integrated management of the information on rice breeding generation from the crossing parents to the released varieties. It is also a decisi
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
