새로운 참깨품종 ‘밀성’을 농촌진흥청 작물시험장 영남 시험장에서 2007년에 개발하였다. 교배조합은 이리4호와 ‘수원131호’로 고품질, 다수성, 내병성을 목적으로 하였다. ‘밀성’은 계통육종법을 이용하여 생산력검정시험, 지역적응성 검정시험을 거쳐 개발되었다. ‘밀성’은 소분지이고 3과성, 2실 4방의 꼬투리를 가지고 있다. 그리고 ‘밀성’의 개화기는 7월 1일로 표준품종인 ‘양백’보다 2일 빨랐다. 또한 성숙기는 8월20일로 ‘양백’과 같았다. ‘밀성’의 경장은 129 cm로 ‘양백’과비슷했다. 하지만 ‘밀성’은 ‘양백’보다 많은 27개의 착삭절을가지고 있어 밀삭형이다. ‘밀성’의 천립중은 2.79 g으로 ‘양백’보다 컸다. ‘밀성’의 역병저항성 및 도복저항성은 ‘양백’과비슷했고 ‘밀성’의 수량은 98 kg/10a로 ‘양백’보다 5% 증수하였다. ‘밀성’은 유지함량은 ‘양백’보다 적었으나 단백질함량은 많았다. 지방산 중 올레산의 비율은 45.8%였고 세사민함량은 2.8 mg/g, 세사몰린 함량은 3.0 mg/g이었다. A new sesame variety ‘Milsung’ was developed from Yeongnam Agricultural Research Institute, National Institute of Crop Science, Rural Development Administration in 2007. Cross was made by ‘Iri 4’ and ‘Suwon 131’ with high quality and yields capacity and disease resistance. And ‘Milsung’ was followed by breeding methods of pedigree selection, yield performance trials and regional yield trials by the sesame breeding team at the National Institute of Crop Science. ‘Milsung’ has a few branch with tri-capsuled, bi-loculi and quadri-carpellates. And the color of flower is light pink. Flowering date of ‘Milsung’ was Jul 1st which was two days earlier than that of the check variety ‘Yangback’. Maturing date of ‘Milsung’ was Aug 20th which was same to that of the check variety ‘Yangback’. Plant height of ‘Milsung’ was 129 cm which was similar to that of the check. But ‘Milsung’ had 27 capsuled nodes which was more than those of the check. So ‘Milsung’ showed very dense capsuled shape. Disease and disaster resistance including phytophthora blight and lodging were similar to the check. The yield of ‘Milsung’ was 98 kg/10a which increased by 5% compared to that of the check. Oil content of ‘Milsung’ was lower than that of the check but higher in protein. Oleic acid composition of fatty acid was 45.8 percent. The contents of sesamin is 2.8 mg/g and those of sesamolin is 3.0 mg/g.

Application of genotype by environment (G × E) interaction would be used for identifying optimum test condition of the varietal adaptation in the establishment of breeding purpose. Yield and yield components were used to perform additive main effect and multiplicative interaction (AMMI) analysis. Significant difference for G × E interaction were observed for all variable examined. For yield, 0.18 of total sum of squares corresponded to G × E interaction. Correlation analysis was carried out between genotypic scores of the first interaction principal component axis (IPCA 1) for agronomic characters. Significant correlations were observed between IPCA 1 for yield and capsule bearing stem length (CBSL), number of capsule per plant (NOC). The biplot of grain yield means for IPCA1 which accounted for 34% of the variation in total treatment sums of squares showed different reaction according to G × E interaction, genotypes and environments. Taegu showed relatively lower positive IPCA1 scores, and it also showed smaller coefficient variation of yield mean where it is recommendable as a optimal site for the sesame cultivar adaptation and evaluation trial. In case of variables, Yangbaek and M1 showed relatively lower IPCA1 scores, but the score direction showed opposite each other on the graph. Ansan, Miryang1, Miryang4, and Miryang6 seemed to be similar group in view of yield response against IPCA1 scores. These results will be helpful to select experimental site for sesame in Korea to minimize G × E interaction for the selection of promising genotype with higher stability.

심강보,김민태,김성국,정건호,전원태,신수현,이재은,이종기,권영업 한국환경농학회 2018 한국환경농학회지 Vol.37 No.3

BACKGROUND: Mixed cropping of legume and grass was effective system in view point of providing organic matter and nitrogen or reducing the nitrogen starvation of following crop. The relation of the change of N and P constituents depending on the cropping types and those effects on the growth and nutrient uptake of the following crop were observed. METHODS AND RESULTS: Three cropping types, hairy vetch mono cropping, barley mono cropping, and mixed cropping of hairy vetch and barley were applied. Soil properties, growth characteristics, and nitrogen production of green manure crops were observed. In additions, the effect of cropping types on the growth pattern of corn as the following crop was observed. In the mixed cropping system, creeping type hairy vetch climbed to the erect type barely for light utilization resulting in improvement of light interception rate and higher LAI (Leaf Area Index) than in mono cropping. Mixed cropping showed higher biomass production and soil nitrogen availability among the cropping types, indicating relatively much more nutrient supply and higher yield production of following crop. CONCLUSION: Mixed cropping showed relatively higher LAI (dry matter) mainly because of intense competition for light utilization usually after flowering stage. Mixed cropping also showed relatively higher yield of corn, the following crop rather than other types, mainly due to the more biomass production potential and higher N and P production ability. Therefore, mixed cropping was adaptable method to reduce or replace chemical fertilizer application for environmentally-friendly agriculture.

심강보,신성휴,손지영,강신구,Woonho Yang,Sunggi Heu 한국작물학회 2016 Journal of crop science and biotechnology Vol.19 No.2

Sesame (Sesamum indicum L.) is an important edible oil crop. Meteorological factors such as temperature, rainfall, and the amount of solar radiation determine the yield potential of sesame. To identify phenotypic diversity and to infer genotypic backgrounds in a collection of 250 sesame germplasm accessions, we classified the germplasm based on variation in morphological traits using principal component (PC) and cluster analysis. The sesame germplasm was grouped based on five PCs, which accounted for 82.3% of total variation. The first PC (PC1) was positively correlated with days to flowering, days to maturity, and number of capsules per plant, whereas the second PC (PC2) was negatively correlated with all characteristics except capsule-bearing stem length. The third component (PC3) was highly positively correlated with capsule length and plant height. We constructed a scatter diagram of the first two PCs (PC1 vs. PC2), revealing four distinct groups of eigenvectors. Most sesame germplasm was widely distributed among Groups I, II, III, and IV. Group III showed a wide range of distribution in the diagram. Otherwise, the distribution of the 250 germplasm accessions was more compact in a scatter diagram of PC1 vs. PC3 compared with PC1 vs. PC2. Groups I, II, III, and IV contained 142, 102, 2, and 3 sesame germplasm accessions, respectively. The two germplasm in Group III were collected from different regions, as were the three germplasm in Group IV. The results show that the distribution of sesame origin is wider than the regions examined in view of phenotypic diversity.

파종시기에 따른 참깨 수량구성요소 및 수량에 미치는 영향

심강보,신명나,전원태,한아름 한국작물학회 2021 한국작물학회지 Vol.66 No.4

The yield potential of sesame depends on genetic factor, environmental factor, genetic x environmental interaction, as well as agronomic factors such as sowing date, planting density or seed rate for sowing. The main aim of this study was to analyze the effects of different sowing dates on the yield-related traits and total seed weight of sesame. The analysis of variance revealed that different sowing dates affected sesame yield-related traits such as plant height, number of branch per plant, number of capsule per plant, 1,000-seed weight, and total seed weight. Early or late sowing date showed negative effect of yield-related sesame traits and total seed weight. Optimum sowing date for sesame in the middle region of Korean peninsula was May 10th, in which total seed yield recorded 90 kg per 10 are. Path-coefficient analysis revealed that the number of capsule per plant and plant height were major factors that affected the total seed weight of sesame across different sowing dates. 파종시기를 달리하여 참깨 수량구성요소 및 종실수량에미치는 영향과 수량구성요소 간 상호 연관성을 구명하고자2019부터 2020년까지 수행하였으며, 그 결과를 요약하면다음과 같다. 1. 참깨를 만파하면 기본적인 생육량이 확보되지 않은 상태에서 생식생장으로 전환되어 초장, 분지수, 주당삭수의 감소로 궁극적으로는 총 종실 수량이 감소하였으며, 조파 시 저온으로 인한 유효적산온도 및 일조시간 확보불충분으로 총 종실 수량이 줄어드는 경향을 보였다. 2. 우리나라 기상조건에서 참깨 파종적기인 5월 상순에 파종하면 평균 주당삭수는 103개로 다른 파종기보다 4~44 개 정도 많았으며 종실수량도 90 kg/10a으로 다른 파종기대비 5~70 kg정도 많았다. 3. 회귀분석을 통한 참깨 수량구성요소의 종실수량에 대한연관성 정도를 비교하여 본 결과 주당삭수가 가장 크게(R2 =0.7211) 나타났으며 분지수(R2 =0.1896)가 가장 적었다. 이러한 차이는 온도나 일장 등 재배환경에 대한수량구성요소의 감응도 차이, 관련요인 간 상호작용, 공시품종의 일장 및 온도반응성 정도 등 복합적인 요인이관여하는 것으로 판단되었다. 4. 경로분석을 통해 참깨 총 종실수량에 미치는 직접효과는 주당삭수 0.621, 초장 0.521, 천립중 0.086 순으로 크게 나타났다. 직접효과와 간접효과를 합한 총 효과는 주당삭수가 0.921로 가장 높았으며 초장 0.889, 분지수0.482, 천립중 0.345 순으로 나타났다. 따라서 조파, 만파 시 불량 기상환경조건에서 주당삭수를 많이 확보할수 있는 품종 선정이 필요할 것으로 판단되었다.
