‘Clara’ 품종은 국립원예특작과학원에서 2005년도에 육성한 포인세티아 품종으로 초장이 작고 컴팩트한 수형으로 포엽의 형태는 난형이며 엽맥 사이 주름의 정도는 약하다. 포엽의 길이와 폭, 잎몸의 길이와 폭, 엽병의 길이는 짧으며 단일처리 후 약 9주일이 경과하면 충분히 착색되어 출하가 가능한 품종이다. 2008년 5월과 10월 ‘Clara’ 품종의 캘러스가 형성된 삽수에 100Gy의 감마선을 24시간 동안 처리하여 유기한 돌연변이를 이용하여 2010년과 2013년에 국립원예특작과학원에서 ‘Clara Pink’와 ‘Clara White’품종을 육성하였다. 이 두 품종들은 포엽의 색이 완전히 변한 변이주를 선발하여 계통화 하였으며 2008년 5월에 감마선을 처리한 삽수들 중 포엽의 색이 분홍색인 변이지를 선발하여 2009년에 2차에 거쳐 특성검정을 실시하였다. 2010년에 ‘원예 D5-2’를 육성한 후 3차 특성검정과 품종평가회를 실시하여 최종선발하였으며, 농작물 직무육성 신품종선정위원회를 거쳐 ‘Clara Pink’로 명명하였다. 2005년 10월에 감마선을 처리한 삽수들중에서는 포엽의 색이 연황색인 변이주를 선발하여 계통화 하였으며, 2012년과 2013년에 1,2차 특성검정을 실시하였다. 2013년에 ‘원예 D5-34’를 육성하여 특성검정과 품종평가회를 실시하고 농작물 직무육성신품종선정위원회를 거쳐 ‘Clara White’로 명명하였다. ‘클라라 핑크’와 ‘클라라 화이트’ 두 품종 모두 ‘클라라’ 품종과 같은 소형으로 적심하지 않은 상태에서도 분지가 많이 발생하는 컴팩트한 수형이다. 포엽의 형태는 결각이 없는 난형이며, 엽맥 사이에 약한 주름이 있고 단일처리 후 약 9주일 경과하면 완전히 착색된다. 잎몸의 모양은 난형이며, 엽병의 길이는 짧다. 그러나 ‘클라라 핑크’와 ‘클라라 화이트’ 품종의 포엽과 엽맥의 안토시아닌 발현에 차이를 나타내었다. ‘클라라 핑크’ 의 포엽은 분홍색이며, ‘클라라 화이트’의 포엽은 연황색이다. 또한 ‘클라라 핑크’ 와 ‘클라라 화이트’ 품종은 ‘클라라’ 품종과 비교해서 잎자루 윗면의 안토시아닌 발현 정도가 약하였으며, 잎몸 윗면의 가운데 맥의 색이 ‘클라라’ 품종은 녹색과 빨강색이 함께 발현되었으나, ‘클라라 핑크’ 와 ‘클라라 화이트’ 품종은 녹색만 발현되었다.

The earth has been facing a rapid warming during past several decades. To figure out the impact of high temperature on agronomic performance of rice especially on yield, we cultivated 89 rice varieties of various origin in Suwon Korea, Shanghai China and IRRI Philippines(Wet season and Dry season). Days to heading, culm length, panicle length, panicle number, spikelet number, spikelet fertility, grain weight and grain yield were comparatively investigated. Overall grain yield displayed significantly lower values in Shanghai and IRRI(wet and dry) compared with in Suwon. Meanwhile minimum values were much lower in Shanghai and IRRI than in Suwon. However, some varieties such as Keunseom, Taichung178 showed similar performance for grain yield in both Suwon and IRRI(wet season), and some varieties such as Hangangchal, Dasan showed similar performance for grain yield in Suwon, Shanghai and IRRI(wet season), Nampung showed very high yield in Suwon comparing to other two locations. For most varieties, grain yield was the highest in Suwon and followed by in Shanghai and at IRRI(wet season). However, in dry season at IRRI, yield trend was quite different from the expectation. Further studies are in progress to find out the genotype by environment interactions in order to obtain basic information for breeding high temperature tolerant rice.

A new garden pea cultivar, Daehyup 2, was developed at the Yeongnam Agricultural Research Institute (YARI) in 2006. It was selected from the cross between Olwandu and Sachulwandu in 1996. The preliminary, advanced, and regional yield trials for evaluation and selection of this cultivar were carried out from 2003 to 2006. It has white flower, yellow cotyledon, absent or very weakly curved pod shape and yellow seed color. It was resistant to virus and powdery mildew disease. The 100 green seed weight of Daehyup 2 was 65.5 g, which was 8.9 g heavier than check cultivar. The sucrose and total sugar contents of fresh pod of Daehyup 2 were 11.1% and 12.5%, respectively, which were 3.2% and 4.3% higher than those of Sachulwandu. The fresh pod yield of Daehyup 2 was similar to that of Sachulwandu with 12.16 ton per hectare in the regional yield trials carried out in three locations of Korea from 2005 to 2006.

Hopyeongbyeo is an anther culture derived Japonica rice (Oriza sativa L.) cultivar from the cross between Hitomebore and Hwajinbyeo by the rice breeding team of Honam Agricultural Research Institute (HARI), NICS, RDA, in 2003. This cultivar has a about 126 days growth duration from transplanting to harvesting. The short and round grain shape of Hopyeongbyeo is translucent with non-glutinous endosperm. Amylose content of rice grain is about 17.8% and high palatability of cooked rice compared with Nampyeongbyeo. This cultivar shows resistant to bacterial blight pathogenes of K1. The milled rice yield of Hopyeongbyeo is about 5.13MT/ha at ordinary transplanting culture in the local adaptability test. Hopyeongbyeo would be adaptable for the southern plain area of Korea.

A single cross hybrid “Gangilok” is an yellow semi-dent maize (Zea mays L.) developed by the Maize Experiment Station at Gangwon-do Agricultural Research and Extension Services in 2005. “Gangilok” has high yield of dry matter, total digestible nutrients (
