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
Improving grain yield and quality of japonica rice continues to be a major breeding objective in Korea. In this study we evaluated genetic divergence among four japonica rice cultivars and assessed the relationship between genetic distance and hybrid perf
Forty-four F1 hybrids derived from crosses among eleven temperate japonica rice cultivars were grown and evaluated for traits related to cold tolerance including days to heading and spikelet fertility in the cold-water irrigated plot (17℃) and
Two split-hull mutants were induced a) by the treatment of chemical mutagen, N-methyl-N-nitrosourea (MNU), in the fertilized egg cells of Hwasunchal and b) in the progeny crossed between Stay-green and Indica-like mutant lines. This study was carried out
Genetic relationship of the 31 Asian pears were distinguished through the principal component (PC) analysis using 34 morphological characteristics and 130 RAPD polymorphisms. The three major PCs were represented about 19 morphological characteristics whic
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

A new soybean variety, “Sunam” was developed from the cross between Kosuzu and Bukwangkong by soybean breeding laboratory of the National Honam Agricultural Experiment Station (NHAES) in 2002. The preliminary, advanced, and regional yield trials for evalu
A new sprout-soybean variety, “Dagi” was developed from the cross between Namhaekong and D70-6545 by the soybean breeding laboratory of the National Honam Agricultural Experiment Station (NHAES) in 2002. The preliminary, advanced, and regional yield trial
A new soy sauce and soy paste soybean cultivar, “Hojang” was developed from the cross between HS12 (Jangyeobkong/Hwangkeumkong) and Suwon153 by the soybean breeding laboratory of the National Honam Agricultural Experiment Station (NHAES) in 2002. The prel
Shinnamjag is a round, smooth, white-skinned, and fleshed potato cultivar with erect plant shape and early maturity. It has excellent table quality. Its yields are high, especially with prominent marketable yield compared to Superior, a leading potato cul
Gahwang is an excellent chipping cultivar with yellow flesh, short oval tuber shape and mid-early maturity. Its yields were a little higher than Atlantic through the regional trials with five locations. It has a lower incidence of internal brown spot comp
A new mungbean variety Samgang (Vigna radiata (L.) Wilczek) was improved from the cross between Keumseongnogdu and V2939 at the Jeollanam-do Agricultural Research & Extension Services (JARES) in 2002. Samgang has erect growth habit, lobed leaflet, green h
A single cross, Jangdaok, is an yellow dent maize hybrid (Zea mays L.) developed by the maize breeding team at the National Institute of Crop Science (NICS), RDA in 2003. This hybrid, which has a high yield of dry matter, total digestible nutrients (TDN)
