‘MS-CDE’와 ‘VFR’의 고정된 계통을 교배하여 특성 및 수량이 우수한 F1 품종인 ‘TY알토랑’을 육성하였다. ‘TY알토랑’의 주요특성은 TMV, TYLCV, 근부위조병, 잎곰팡이병에 내병성이며, 2~3월, 7~9월에 정식하는 품종으로 숙기는 중조생종으로 평균과중 225 g 내외의 고구형의 완숙 대과종토마토이다. 경도가 강하여 저장성이 우수하고 과형이 정연하며, 착과가 안정되어 수량성이 높다. 또한 초세가 강하면서 이상줄기 발생이 적어 재배가 안정적인 품종이다.

큰섬'은 국립식량과학원 기능성작물부에서 재배안전성이 높은 초다수성 벼를 육성하고자 1996년 하계에 초형이 양호하고 흰잎마름병에 저항성이며 초다수성인 '다산벼'에 벼멸구와 바이러스에 저항성인 남영벼를 인공교배 하였다. 그 후에는 집단육종법과 계통육종법을 병행 실시하여 미질이 좋고 생육특성이 양호한 계통 YR18234-B-B-98 -3-5-1을 선발하였다. 생산력검정 시험과 2003년부터 2006년까지 4년간 지역적응시험을 실시한 결과 그 우수성이 인정되

This study was carried out to breed and develop high quality and functional nutrient tomato with multi disease resistance as well as a stable growing adaptation for fresh market usage under protected plastic houses cultivation. The materials were used 5 inbred lines and their 6 hybrids of large tomato group, which have been bred and developed from 1999 to 2007 in Division of Plant Resource Department of Chungnam National University. Fruit weight showed hybrid vigor effect that F1 hybrids weighed more than their parent lines, fruit shape formed three type of oblate, deep oblate and globe shape, in firmness and pericarp thickness have got a high significant correlation, inbred DN611 line was measured the most firm fruit with 6.04 mm pericarp thickness. In fruit color at maturity, pink color crossed to red color appeared all red fruit color in the F1 hybrids, it means red skin color is a dominant gene compared to pink skin color is a recessive gene in tomato, while between fruit skin color and shoulder part color showed no any co-relationship. The sugar content and titratable acid of F1 hybrids inherited an intermediate data of their parent lines, the flavor of KP543 inbred line and the hybrid (JB535 x KP543) revealed the better taste with high brix and proper titratable acid content*. In beta carotene content DN611 line showed 2~3 times higher than other materials so that its 3 hybrids contained an increased level of beta carotene, lycopene content was not so much difference among inbred lines and F1 hybrids, of them MD508 contained higher of 8.72 mg and hybrid (JB535 x JA517) had 8.05 mg lycopene content per 100 g fruit, overall pink skin color and red skin color measured a higher lycopene content than yellow and orange skin color at ripe stage. In disease resistance test by PCR marker for Fusarium race2 (I2), Nematode (Mi1), ToMV (Tm22), Cladosporium (Cf9), (JB535 x JA517) hybrid have got multi-resistance with homozygote band in Nematode, ToMV, Cladosporium and heterozygote band in Fusarium race2. Through this breeding program we could select high quality and functional nutrient with multi resistant F1 hybrids and inbred lines in tomato which are two best hybrids (JB535 x MD508), (JB535 x JA517), additionally developed high beta carotene inbred line DN611 and increased the level of lycopene inbred line MD508. These results will be very useful to make a high quality tomato variety continuously.

Hopum is a new japonica rice cultivar developed from the cross between Milyang165 and F1 crossing Milyang165 and Iksan438 at Department of Rice and Winter Cereal Crop, NICS, RDA, in 2006. This cultivar has a short grain shape and about 141 days growth duration from direct seeding to harvesting in the southern plain including Chungcheong province. This cultivar has short culm and spikelet number per panicle is similar to that of Nampyeongbyeo, while filled grain rate is lower than standard variety. This cultivar has medium size of brown rice and shows moderate resistance to leaf blast, to bacterial blight pathogens of K1, K2 and K3 and stripe virus disease but susceptible to major virus diseases and insect pests. The milled kernel of Hopum is translucent with non-glutinous endosperm. Protein and amylose content of Hopum is about 6.5% and 18.7%, respectively. This cultivar has better palatability of cooked rice than Chucheongbyeo harvested in Gyeongki province. Its milling recovery (76.8%) and percentage of perfect-shaped milled rice (94.7%) were higher than Nampyeongbyeo. The milled rice yield of Hopum was 5.83 MT/ha (15% higher than Juan) under wet-direct seeding, 5.66 MT/ha (8% higher than Juan) under dry-direct seeding, and 6.00 MT/ha (8% higher than Nampyeong) under ordinary transplanting cultivation. “opum”would be adaptable for ordinary transplanting and direct seeding in the southern plain including Chungcheong province.

Areumbyeo', a second generation Tongil-type rice variety (Oryza sativa L.), has been developed at National Yeongnam Agricultural Experiment Station (NYAES) from 1983 to 1999 and released in 2000. A single cross between YR3299-34-2-2 and Suweon 318 (was co
