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
Growth analysis was conducted with three diff erent growth types of sesame to compare the growth characteristics among types and to obtain the basic information for breeding high yielding sesame. Dif ferent growth types showed dif ferent rate of inrease i
This study was carried out to investigate the ef f ect of nitrogen level and planting density on panicle traits and to exam -ine the desirable panicle structure for better ripening and high yielding in rice. Four dif f erent panicle types of rice varietie
AFLP markers were successfully employed to detect genetic relationship and genetic variation within and between Oryza species. Analysis of 59 accessions of Oryza species with six AFLP prim er combinations detected a total num ber of 715 polym orphic bands
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
The mode of inheritance and allelic relationship of resistance genes in a Korean landrace, Guju and a Korean weedy rice, Geumleungaengmi 33 were studied using Korean isolate (HB9101, race K1) of Xanthomonas oryzae pv. oryzae. The analysis of F1
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
The subspecies-specif ic RAPD markers were identif ied using 30 varieties (15 japonica and 15 indica) from diverse geographical origins. Of 690 random primers tested including subspecies-specif ic (SS) RAPD markers reported earlier, 55 primers generated 6
Three anthocyanins were isolated from the acidif ied ethanol extract of black soybeans (Glycine max M. cv. Geom jeongkong 1) using preparative high-performance liquid chrom atography. The anthocyanins were characterized as delphinidin 3-glucoside (D3G), c
A new two-rowed naked waxy barley cultivar, 'Pungsanchal', was developed for split polished grains by the National Crop Experiment Station(NCES), RDA in 2001. This cultivar was derived f rom a cross between 'SB901258GG-B' and 'Suwon212' in 1991. The f ina
Sanglog', a new covered barley cultivar resistant to powdery mildew and barley yellow m osaic virus (BaYMV) was developed by the barley breeding team of the National Crop Experim ent Station (NCES), RDA in 1999. This variety was derived from a cross betwe
“Jaeanchal” is a new six-rowed, naked and waxy barley cultivar developed by National Crop Experiment Station (NCES), RDA in 2001. This cultivar was derived from a cross between “Suwon261” and “SB881115-6” in 1989. The final selection was made at NCES in 1
Poongmi is the first ginger variety developed by pure line selection from 54 Korean local accessions. The selected pure line having high quality and high yielding was tested for regional adaptation, and it was superior to those traditional accessions in g
A new malting barley cultivar, “Sinho”, with a resistant gene (rym5) to barley yellow mosaic virus (BaYMV) was developed by the barley breeding team of National Crop Experiment Station (NCES), RDA in 1999. This cultivar was derived from the cross between
“ Namahn” (Sesamum indicum L.) was developed at the National Honam Agricultural Experiment Station (NHAES) in 2001. It was derived from the cross between “Suwon87 ” of white seed coat color and short stem, and “Nongki S-2” of phytophthora blight tolerance
A new peanut variety “Dakwang (Arachis hypogaea L.)” was developed from the cross between Suwon80 and ICG11 at the National Honam Agricultural Experiment Station(NHAES) in 2001. This variety has Shinpung type and erect growth habit with large size obovate
A new soy sauce and soy paste soybean variety, “Jinmi” was developed from the cross between HS12 (Jangyeobkong/Hwangkeumkong) and Mallikong by the soybean breeding team of the National Honam Agricultural Experiment Station in 2001. The preliminary, advanc
A new six-rowed naked barley cultivar, “Saenul”, was developed from a double cross between the F1 of Yonezawamochi/Olbori and Dangomugi at National Honam Agricultural Experiment Station RDA in 2001. It has the traits of early maturity, cold resistance, re
“Joeun” is a new semi - hard wheat variety with early maturity and good milling quality. It was developed from a cross between “Eunpamil” and “Suwon 242” at the National Crop Experiment Station, RDA. “Eunpamil” as a female parent was medium in plant heigh
