“Jokyoung”, a new bread making wheat cultivar, was developed from the cross between “Seri 82”, a hard white wheat from CIMMYT, Mexico and “Keumkang”, a hard white wheat with high milling rate and early maturing from Korea by National Institute of Crop Sci

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

The genetic basis underlying heterosis for agronomic traits of rice under cold water irrigated field condition was investigated in the 143 RILs and 286 BC₁F₁ lines from the cross between a cold-susceptible variety, Milyang23 and a co

The elite rice cultivar, Suweon365, shows high level of leaf blast resistance. The number and chromosomal locations of genes conferring the resistance were detected by linkage analysis using DNA markers in the RILs from the cross between Suweon365 and Chu

Ilpumbyeo, a japonica rice cultivar which is known to have premium eating-quality, and high yield potential, but susceptible to rice blast disease was studied whether it has any specific rice blast resistance gene/QTL. Using CAPS markers which were develo

Genetic diversity of 94 japonica rice was assessed using 81 simple sequence repeat (SSR). All 81 SSR markers generated a total of 351 alleles. The number of alleles ranged from 1 to 16 with a mean of 4.3 alleles per SSR marker. Six of 81 SSR markers showe

In order to measure an antifreezing tolerance, antifreeze proteins accumulated upon cold acclimation in apoplast were analyzed. As Dongborilho were cold-acclimated for 3 to 74 days there was an abrupt increase in apoplastic proteins up to 30 days and then decrease to the similar levels. Among the known antifreeze proteins, CLP produced in E. coli. and TLP purified from apoplast were used to generate antisera that allow to measure and localize the proteins in leaves of barley. The CLP of 27.7 kDa and TLPs of 6, 26, 27, 30, and 31 kDa were increased in their amounts in apoplast as cold treatment being longer. There was a correlation among the amounts of those proteins accumulated in apoplast and freezing tolerance as shown in field and ion leakage tests for five cultivars. The deposit of CLP was localized in the marginal area and the area adjacent to leaf vescular bundle cells in an increasing manner according to duration of cold acclimation but no variation was observed in terms of it's distribution. Based on the close correlation between levels of antifreeze proteins and degrees of freezing tolerance, the immunological methods was to develop to estimate a freezing tolerance in barley

"Seolhyangchalbyeo", an aromatic and glutinous rice cultivar, was developed by the rice breeding team of National Crop Experiment Station, RDA during the period from 1991 to 1999 and released in 2000. The cultivar is derived from a cross between Miyagaori

Andabyeo, a new Tongil-type rice (Oriza sativa L.) cultivar, is developed by the rice breeding team of National Cropbetween SR11532-4 and SR14502F2. This cultivar has about 115 days of growth duration from seeding to heading and is semi-dwarf (culm length
