The production and productivity of major crop plants have reached their plateu during the past decade because of adop-tion of green revolution technologies. However, further increase in production of cereals with improved cereal quality is imperativeto fe
We have analyzed the genetic diversity of 45 squash genotypes in Cucurbita maxima, C. moschata, C. pepo and uniden-tified Cucurbita spp. (noodle-squash) with molecular markers. The 45 squash accesions showed molecular variations of 87.5% inRAPD and 74.4%

Soybean cyst nematode (Heterodera glycines Ichinohe, SCN) is an important soybean pest and the use of resistant cul-tivars is an effective method to reduce or eliminate SCN damage. SCN resistance loci, rhg1 and Rhg4 are generally accepted as anecesity for
This study was carried out to understand the genetic pattern of self-sterility, using a self-fertile variety Cheongyangnative 1 and nine self-sterile cultivars in cultivated boxthorn (Lycium chinense Mill., 2n=24). The inheritance of self-fertility (SF)wa
Genetic diversity and phylogenetic relationships among five cultivated Capsicum species were assessed using both mor-phological characters and DNA finger-printing patterns. Based on the clustering analysis using morphological characters withineach species
Diversity and relatedness of 64 rice accessions were evaluated using 85 simple sequence repeats (SSRs) markers. These64 accessions represent a set of international and Korean blast diferential cultivars, a set of blast monogenic lines, donors of blastresi
The Korean native rice collection consists of landrace and weedy strains. The weedy strains are represented by two dis-tinctive populations, Share and red rice. The 242 representative accessions of Korean native rice collection were selected basedon the p
Sundoo, new variety of kidney bean (Phaseolus vulgaris) was developed by Gyeonggi-do Agricultural Research andExtension Services in 2001. It was bred by pure line selection from Yangpyeng local collection. Sundoo has determinate growthhabit, ellipsy round
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
Anseongbyeo is a japonicaseed weight of three near-isogenic lines of blast resistance. The recurrent parent, Suweon345, was a high-quality and semi-dwarf rice cultivar with susceptability to neck blast. The blast-resistance donors for each liens were SR12
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.
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
“Saechucheongbyeo” is a new japonica multiline for blast resistance, which was composed of equal proportions in seed weight of three near-isogenic lines of two combinations. The recurrent parent, “Chucheongbyeo”, was a high-quality rice cultivar with susc
“Surabyeo” is a new japonica rice cultivar developed from a backcrossed combination between the F1 of “Suweon 345/ Kanto PL4” and “Suweon 345” of lodging tolerant, semi-dwarf, high-quality rice line by the rice breeding team of National Crop Experiment St
“Undoobyeo” is a japonica rice cultivar (Oryza sativa L.) developed by the rice breeding team in the National Crop Experiment Station, RDA, Suwon, Korea in 1998. Undoobyeo was derived from a cross between Odaebyeo and Jinbu 13 made during 1989/'90 winter
A new soybean variety “Geomjeongkong 3” was released by the National Crop Experiment Station, RDA, in 2001. This variety was derived from the cross between Shinano-kuro and SNU78010, the elite breeding line with large seed, in the summer season, 1990. The
