  • This research was conducted to determine the contents of sugar and starch between rice cultivar, ASD1 being with high seedling establishment under direct seeding cultivation and IR72 being with poor seedling establishment. The ASD1 rice cultivar was higher in sugar and starch contents than those of IR72 during germination. This result was proven to the previous research out­put with high seedling establishment in direct seeding condition as well.

  • 전북 서해안 새만금 지역에 조성되는 간척지 면적 28,300ha의 30%인 8,400ha 정도가 농업용지로 사용되는 계획이 확정됨에 따라 해당 용지를 효율적으로 사용 할 수 있는 다양한 활용 방안이 요구되고 있다. 대단위 농업지구가 들어설 예정지인 새만금 광활 간척지는 네덜란드와 유사하게 토양의 대부분이 미사질 양토로 이루어져있어 적용 가능한 화훼류를 적절히 선발하고 적합한 재배기술을 도입한다면 대규모 화훼제배 단지로서의 성장 가능성이 충분할 것으로 판단된다. 따라서 전북 농업기술원에서는 2004년부터 7년에 걸쳐 새만금 간척지의 농업적 활용도 제고와 경관농업 육성을 통한 관광자원화 가능성을 확인하기 위하여 72종의 원예작물 적응시험을 실시하였으며 22종의 자생식물과 튤립, 아이리스, 수선화, 히아신스, 참나리 등 5종의 구근 화훼류를 적합 화훼류로 선발하였다. '08~09년에는 내염성과 저온 및 풍해 저항성이 있는 아펠톤, 골든아펠톤, 네그리타, 프랑소와즈, 키스네리스 등을 간척지적용 가능 주요 튤립 품종으로 선발 하였는데 선발된 품종들을 대상으로 높은 염농도 하에서의 체내축적 무기성분을 조사한 결과, K와 Mg은 증가되는 경향이었으나 Ca은 감소되었으며, Cl이온은 현저하게 증가하였다. 또한 튤립체내의 산도 및 전기전도도와 항산화효소의 활성이 증가하였는데 스트레스 반응결과 유해산소가 체내에 축적되고, 이를 중화시키기 위하여 수소이온을 소모함으로써 체내의 산도는 상승된 것으로 추정되며 염분함량이 높을수록 삼투압에 의하여 뿌리에서 흡수는 양분이 적은 반면 잎 줄기의 증산작용은 동일하기 때문에 상대적으로 체내의 농도가 높아져 전기전도도가 상승된 것으로 판단된다. 식물 스트레스의 지표물질로 사용되고 있는 proline 함량도 토양내의 염도가 상승되면서 증가되었으며 엽록소 함량은 감소되는 경향을 보였다.

  • 작물의 생산성은 재배작물의 품종이 갖는 유전적 특성과 재배기술 및 재배환경에 의해 결정되는 것으로, 이중 품종과 기술은 육종가와 재배기술자의 노력으로 많은 발전을 가져오고 있지만, 재배환경은 인위적으로 조절할 수 없는 부분이 많고 특히 기상환경은 자연기상조건에 의존하고 있다. 그러므로, 특정 지역에서 재배하는 작물과 품종은 그 지방 기후에 적응되는 과정을 거쳐 그 지역의 풍토에 알맞게 진화되어 왔다고 볼 수 있다.(중략)

  • 'Manjong' is a new japonica rice cultivar developed in 2009 derived from a cross between 'Yeongdeog34' and 'Nampyeongbyeo' at the Department of Functional Crop, NICS, RDA. This cultivar is suitable for the double cropping system after the cash crop cultivation. Heading date of 'Manjong' is later than 'Keumobyeo' under the late transplanting cultivation on July 10. It has high grain fertility under cold conditions and low premature heading. One of the distinguishing characteristics of this variety is its resistance to major diseases like leaf blast and rice stripe virus disease. However, it shows susceptibility to major insect pests and bacterial blight disease. Milled rice kernels are translucent with non-glutinous endosperm and have 7.2% protein and 18.7% amylose contents. Ripening ratio and head rice ratio is very higher than those of 'Keumobyeo'. The palatability of cooked rice is also better than 'Keumobyeo'. The milled rice yield of 'Manjong' in local adaptability tests after harvest of the cash crop is $4.81MT\;ha^{-1}$. This cultivar is suitable for planting in the plain paddy fields of Honam and Yeonnam regions in Korea.

  • "Sangok", is a new japonica rice variety (Oryza sativa L.), which is a midium maturing ecotype developed by the rice breeding team of National Yeongnam Agricultural Experiment Station (NYAES) in 2003. This variety was derived from the cross of Milyang 101/YR8697Acp97 (in 1988/1989 winter) and selected by combination of the bulk and pedigree breeding. The pedigree of Sangokbyeo, designated as Milyang 182 in 2000, was YR12950-B-B-B-19-2-4-2-2. It has about 79cm stature in culm length and is medium maturing. This variety is resistant to bacterial blight ($K_1$, $K_2$, and $K_3$), stripe virus and moderately resistant to leaf blast disease. Milled rice kernels of "Sangok" is translucent, clear in chalkness and good at eating quality in the panel test. The yield potential of "Sangok" in milled rice is about 5.16MT/ha at ordinary fertilizer level of local adaptability test. This cultivar would be adaptable to the southern plain of Korea below the Chungnam province by latitude from ordinary transplanting to transplanting after barley harvest.

  • 'Aram' is a soybean cultivar developed for soy-sprout. It was developed from the crossing of 'Bosug' (Glycine max IT213209) and 'Camp' (G. max IT267356) cultivars in 2007. F1 plants and F2 population were developed in 2009 and 2010. A promising line was selected in the F5 generation in 2011 using the pedigree method and it was evaluated for agronomic traits, yield, and soy-sprouts characteristics in a preliminary yield trial (PYT) in 2012 and an advanced yield trial (AYT) in 2013. Agronomic traits and yield were stable between 2014 and 2016 in the regional yield trial (RYT) in four regions (Suwon, Naju, Dalseong, and Jeju). Morphological characteristics of 'Aram' are as follows: determinate plant type, purple flowers, grey pubescence, yellow pods, and small, yellow, and spherical seeds (9.9 g 100-seeds-1) with a light brown hilum. The flowering date was the 5th of August and the maturity date was the 15th of October. Plant height, first pod height, number of nods, number of branches, and number of pods were 65 cm, 13 cm, 16, 4.5, and 99, respectively. In the sprout test, germination rate and sprout characteristics of 'Aram' were comparable to that of the 'Pungsannamulkong' cultivar. The yield of 'Aram' was 3.59 ton ha-1 and it was 12% higher than that of 'Pungsannamulkong' in southern area of Korea. The yield of 'Aram' in the Jeju region, which is the main region for soybean sprout production, was 20% higher than that of 'Pungsannamulkong'. The height of the first pod and the tolerance to lodging and pod shattering, which are connected to the adaptation to mechanized harvesting, were higher in 'Aram' compared to those in 'Pungsannamulkong'. Therefore, the 'Aram' cultivar is expected to be broadly cultivated because of its higher soybean sprout quality, and seed yield and better adaptation to mechanized harvesting.
