본 실험은 내습성 품종과 감수성 품종을 5엽기에 9일간 침수 처리한 후 잎과 배축을 대상으로 횡단면을 해부학적 특성을 광학현미경으로 관찰하여 그 결과 다음과 같다. 1. 엽록소함량, 광합성, 책상조직 수, 엽두께 및 잎 건물중은 습해에 의해 급격히 감소되었으며 풍산나물콩보다 소백나물콩의 감소가 더 많았다. 2. 잎 조직의 책상조직의 치밀함은 습해에 의해 급격히 감소되었고 품종간 차이도 관찰되었으며, 풍산나물콩은 주맥의 통도조직 중 목부의 발달을 볼 수 있었다. 3. 배축의 통기조직 형성은 소백나물콩은 보이지 않았으나 풍산나물콩은 피층에 파생통기조직이 형성되는 것을 볼 수 있었다.

“Hyemi”, a new covered cultivar derived from the crosses between “Suwon 298” and “Milyang 34/Albori//Dongbori” developed at the Honam Agricultural Research Institute (HARI), NICS, RDA in 2006. The origin of “Hyemi” is “Suwon 400” (SB951032-B-B-B-28). The initial cross was made in 1995 and the selected line showed a high yield and good quality characteristics under yield trial test in 2003. “Suwon 400” consistently performed well for three years (2004-2006) from the four locations of regional yield trial (RYT) in Korea and released as “Hyemi”. The characteristics of “Hyemi” were the following: rate Ⅳ growth habit, green leaf and stem, compact spike and with long rough awns. The heading date was April 29 in upland and April 23 in paddy field, which was similar and 2 days earlier than that with check cultivar, “Olbori”. The culm length was 81 cm which was 4 cm shorter than those with check cultivar. It showed spike length of 4.1 cm and 646 spikes per m2, 52 grains per spike, 33.4 g of 1,000-grain weight and 672 g of test weight. It showed similar winter hardiness and higher resistance to barley yellow mosaic virus (BaYMV) than those with check cultivar. It showed higher protein content, whiteness and total phenol content than those of the check cultivar, but lower β-glucan content and pearling rate. The average yield of the pearled grain in the RYT was 3.95 ton ha-1 in upland and 4.38 ton ha-1 in paddy field, which was 13% and 16% higher than that of the check cultivar, respectively. This cultivar would be suitable for the area above the daily minimum mean temperature of -8℃ in January in Korean peninsula.
