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

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 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

Genetic diversity and soybean sprout-related traits were evaluated in a total of 72 soybean accessions (60 Glycine max, 7 Glycine soja, and 5 Glycine gracilis). 100-seed weight (SW) was greatly varied and ranged from 3.2g to 32.3g in 72 soybean accessions. Positive correlation was observed between GR and hypocotyl length (HL), whereas negative correlation was observed between SW and hypocotyl diameter (HD). Re-evaluation by discarding two soybean genotypes characterized with low GR indicated that much higher correlation of sprout yield (SY) with HD and SW. Based on the principal component analysis (PCA) for sprout-related traits, 57 accessions were classified. Soybean genotypes with better traits for sprout, such as small size of seeds and high SY, were characterized with high PCA 1 and PCA 2 values. The seed size in second is small but showed low GR and SY, whereas the third has large seed, high GR and more than 400% SY. In genetic similarity analysis using 60 SSR marker genotyping, 72 accessions were classified into three major and several minor groups. Nine of twelve accessions that were identified as the representatives of soybean for sprout based on PCA were in a group by the SSR marker analysis, indicating the SSR marker selection of parental genotypes for soybean sprout improvement program.

A single cross hybrid, 'Heugjeomchal', is a white and black bicolor waxy corn (Zea mays L.) developed by the Maize Experiment Station (MES), Gangwondo Agricultural Research and Extension Services (GARES) in Hongcheon in 2000. 'Heugjeomchal' was made by cr

본 실험은 비중선으로 종자밀도를 5등급으로 세분한 뒤 각 등급별 유묘의 유관속 발달 및 생육 특성에 미치는 영향을 구명하기 위하여 인디카형인 IR58과 자포니카형인 운봉7호를 공시하여 수해한 결과는 다음과 같다. 1. 종자의 밀도가 1.00이하에서 1.20이상으로 높아질수록 유묘의 엽신과 엽초에 발달된 유관속수와 크기가 증가하는 경향이었다. IR58은 운봉7호보다 유관속수와 크기가 양호하게 발달하였다. 2. 유묘의 생육특성인 초장, 엽수, 근수 및 근장은 종자의 밀도가 1.20이상까지 높아질수록 증가하였다. 3. 엽신과 엽초에 발달된 유관속수는 건물중과 고도로 유의한 정의 상관관계를 나타냈으며, 제4, 5엽신의 대유관속수는 엽신폭과 유의한 정상관을 보였다. 4. 종자의 밀도가 높아질수록 유묘의 유관속 발육을 좋게 하며 양수분의 원활한 이동으로 인하여 생육이 양호하게 건묘육성에 바람직하였다.
