Kwanganbyeo is a japonica rice variety developed from the cross between Namyang 7 and SR14779-HB234-31, anelite line derived from the cross between Cheonmabyeo and Aichi 37 at the National Crop Experiment Station, RDA, and washi-tecture and light-dark gre
Junganbyeo is a japonica rice variety derived from a cross of Namyang 72* Hapcheon 1 by the rice breeding team ofNational Crop Experiment Station, RDA, in 1999 and was released in 2000. This is a medium-early variety with growth durationtdark gren leaves.
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
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
