이영희,홍점규,김상희,윤병욱 한국식물병리학회 2014 Plant Pathology Journal Vol.30 No.3

Two cultivars Buram-3-ho (susceptible) and CR-Hagwang(moderate resistant) of kimchi cabbage seedlings showed differential defense responses to anthracnose (Colletotrichum higginsianum), black spot (Alternaria brassicicola) and black rot (Xanthomonas campestris pv. campestris, Xcc) diseases in our previous study. Defense-related hormones salicylic acid (SA), jasmonic acid (JA) and ethylene led to different transcriptional regulation of pathogenesis-related (PR) gene expression in both cultivars. In this study, exogenous application of SA suppressed basal defenses to C. higginsianum in the 1st leaves of the susceptible cultivar and cultivar resistanceof the 2nd leaves of the resistant cultivar. SA also enhanced susceptibility of the susceptible cultivar to A. brassicicola. By contrast, SA elevated disease resistance to Xcc in the resistant cultivar, but not in the susceptiblecultivar. Methyl jasmonate (MJ) treatment did not affect the disease resistance to C. higginsianum and Xcc in either cultivar, but it compromised the disease resistanceto A. brassicicola in the resistant cultivar. Treatmentwith 1-aminocyclopropane-1-carboxylic acid (ACC) ethylene precursor did not change resistance of the either cultivar to C. higginsianum and Xcc. Effect of ACC pretreatment on the resistance to A. brassicicola was not distinguished between susceptible and resistant cultivars, because cultivar resistance of the resistant cultivar was lost by prolonged moist dark conditions. Taken together, exogenously applied SA, JA and ethylenealtered defense signaling crosstalk to three diseases of anthracnose, black spot and black rot in a cultivar-dependent manner.

This study was conducted to provide basic data for chestnut breeding program and the morphological identification system of chestnut cultivars using Korean prevailing chestnut cultivars. European and Chinese chestnut cultivars. There were significant differences among cultivars in blooming time. Cultivars derived from Chinese chestnut showed later blooming patterns than Japanese chestnut cultivars. In most of cultivars, the full blooming period of pistillate flower considered to be optimum for pollination was about 4 days. In the fructification rate, `Tsukuba` showed highest(82.1%), while `Tono 2` was lowest(34.5%). In the optimum harvesting time, the early-maturing cultivar `Moriwase` was earliest at 1 September, while the late-maturing cultivar `Banseki` latest at 13 October. The harvesting period showed significant differences among cultivars, and `Tanzawa`, `Otanba` and `Hamjongyul` were shortest(8 days), while‘Riheiguri` and `Tsukuba` were longest(〉2 weeks). Soluble solids content of nut measured immediately after harvest varied between 9.6% in `Isseumo` to 22.2% in `Hamjongyul`. Nearly cultivars derived from Chinese chestnut showed higher values than Japanese chestnut cultivars in soluble solids content, and nut hardness was similar to soluble solids content. With respect to percentage of polyembryonic nuts, most of cultivars were below 5%, but `Tono 2` was highest(11.2%) resulted in depreciating market values. Percentage with the pericarp split was below 5% in most of cultivars, but `Daab` was highest(32.4%) inferior to other cultivars The UPGMA dendrogram based on nut characteristics was devided into three groups in genetic distance 1.0, and `Hamjongyul`, `Pyungyangyul` and `Cheonjinyul` were distinguished from other cultivars

트리티케일 품종 '조영'은 2015년에 농촌진흥청 국립식량과학원에서 육성되었다. '조영'은 넓이가 중간이고 길이가 긴 녹색 잎과 갈색이면서 중간 길이의 종실을 가졌다. '조영'은 출수기가 전국 평균 4월 30일로 표준품종인 '신영'보다 2일 빨랐으며, 한해는 '신영'과 대등하였고, 줄기가 굵고 초장이 짧아 도복에는 강하였으며, 습해 흰가루병 잎녹병 등에 저항성을 보였다. 생초수량은 ha당 평균 40.5톤, 건물수량은 15.7톤으로 표준품종과 대등하였다. 품질특성으로 '조영'은 '신영'에 비해 조단백질 함량이 5.9 %로 다소 높았고, NDF 및 ADF 함량도 각각 57.3 %와 33.9%로 다소 높았으며, TDN 함량은 62.2 %로 약간 낮았다. '조영'은 종실 수량이 ha당 5.59톤으로 4.05톤인 '신영'에 비해 38 %가 많았다. 적응지역은 1월 최저평균기온이 $-10^{\circ}C$ 이상인 지역이면 전국 어느 곳에서나 재배가 가능하다. 'Choyoung', a winter forage triticale cultivar (X Triticosecale Wittmack), was developed at the Department of Rice and Winter Cereal Crop, NICS, RDA in 2015. The cultivar 'Choyoung' has the leaves of medium width, long length and green color and a medium grain of brown color. The heading date of the cultivar 'Choyoung' was April 30 which was 2 days earlier than that of check cultivar 'Shinyoung'. Its tolerance or resistance to cold, wet injury, powdery mildew, and leaf rust was similar to those of the check cultivar. But the resistance to the lodging of cultivar 'Choyoung' was stronger than that of the check. The average forage fresh and dry matter yield of cultivar 'Choyoung' at milk-ripe stages were 40.5 and $15.7MT\;ha^{-1}$, respectively, which were similar to those (40.3 and $16.1MT\;ha^{-1}$) of the check cultivar. The silage quality of 'Choyoung' was higher than that of the check cultivar 'Shinyoung' in crude protein content (5.9%), while was similar to the check cultivar 'Shinyoung' in acid detergent fiber (33.9%), neutral detergent fiber (57.3%), and total digestible nutrients (62.2%). It showed a grain yield of $5.59MT\;ha^{-1}$, which was 38% higher than that of the check cultivar 'Shinyoung' ($4.05MT\;ha^{-1}$). This cultivar is recommended for fall sowing forage crops in areas in which average daily minimum mean temperatures in January are higher than $-10^{\circ}C$.

Physiological Responses of Soybean Cultivars to Fusarium solani f. sp. glycines Causing Sudden Death Syndrome

Joon Hyeong, Cho The Korean Society of Crop Science 1999 Korean journal of crop science Vol.44 No.4

Six soybean cultivars having different SDS susceptibility were planted with sorghum seedinoculum infested with F. solani isolate 171 in the greenhouse. First leaf symptoms appeared on unifoliar leaves at 9 days after inoculation and all cultivars showed the typical leaf symptoms at 13 days after inoculation, when trifoliar leaves emerged. Leaf symptoms development in susceptible cultivars was faster than in resistant cultivars. Leaf symptom severities during the period of 25 to 29 days after inoculation showed a significant difference between cultivars which had SDS resistance and sus ceptibility. In this period, area under the diseaseprogress curve (AUDPC) of Hartz 6686 was the highest and that of PI 520733 was the lowest. SDS caused serious damage to the growth of soybean in all cultivars. Average reductions of growth rate of root fresh weight and dry weight were greater than those of plant tops. Duyu-kong showed less severe leaf symptoms than that of SDS suscetible cultivars; however, average growth rate of plants top and roots of this cultivar was less but not significantly different than those of SDS susceptible cultivars. In all cultivars, as severity of leaf symptoms increased, plant top weight decreased. Root rot symptoms were observed in all cultivars before leaf symptoms appeared. Average proportions of tap root reddish-brown discoloration of all cultivars was up to 75 % at 15 days after inoculati on; however there was no significant differenc between cultivars at each rating date. Appearances of leaf symptoms on leaves varied in each cultivar. SDS resistant cultivars had a significantly higher level of crinkling than susceptible cultivars and SDS susceptible cultivars had a significantly higher level of necrosis than resistant cultivars. Further study will be needed to identify the relationships between the physiological growth rate and SDS severities in soybeans.

황엄지(Eom-Ji Hwang),이유건(Yu Geon Lee),이형재(Hyoung Jae Lee),조정용(Jeong-Yong Cho),문제학(Jae-Hak Moon) 한국식품과학회 2021 한국식품과학회지 Vol.53 No.4

본 연구에서는 국내 육종 양파[황색(맵시황, 신선황, 연신황, 영보황, 영풍황), 적색(엄지나라), 연녹색(스위트그린)]와 외국 육종양파(황색, 선파워; 적색, 천주적) 간의 일반형질, 주요성분 및 항산화능을 비교하였다. 그 결과, 각 페놀성 화합물과 flavonoid의 성분별 총 함량 및 총 페놀성 화합물과 총 flavonoid 함량에 있어 외래품종인 썬파워를 포함한 6종의 황색양파들 중 영보황이 가장 우수한 값을 보였으며, 적색품종에 있어서는 천주적이 엄지나라보다 약간 높은 함량을 보였다. 총 anthocyan의 함량은 엄지나라가 천주적보다 낮았다. 반면 thiosulfate의 함량은 모든 품종들에 있어 유의차를 보이지 않았으며, pyruvic acid 함량은 황색 양파들 중 영보황과 썬파워가 동일한 정도로 가장 높았고, 적색 품종에 있어서는 엄지나라가 천주적보다 더 높은 함량을 보였다. 그러나 총 당함량에 있어서는 영신황이 썬파워를 제외한 모든 품종들 중 가장 높은 값을 보였다. 그리고 항산화능은 모든 평가항목에 있어 공통적으로 적색품종이 가장 우수하였으며, 환원력에 있어서는 천주적이 엄지나라보다 우수하였으나 DPPH radical scavenging 활성은 천주적보다 엄지나라가 다소 높은 경향을 보였고, ABTS⁺ radical scavenging 활성은 두 품종들 간에 유의차를 보이지 않았다. 황색품종들에 있어서는 신선황과 영보황이 우수한 DPPH radical scavenging 활성을 보였으며, 환원력은 국내산 품종들이 썬파워보다 약간 높은 경향을 보였고, ABTS+ radical scavenging 활성은 영신황이 썬파워보다 높았다. 이상의 결과로부터 국내 육성 품종인 영보황과 엄지나라의 성분학적 및 기능학적 우수성이 부분적으로 제시되어진 바, 본 연구결과가 국산 양파 품종의 우수성 홍보를 위한 유용 자료로 활용되기를 기대한다. The content of major constituents and antioxidant activities of nine onion cultivars, namely yellow domestic cultivars Meapsihwang, Sinsunhwang, Yeonsinhwang, Yeongbohwang, and Yeongpoonghwang, red domestic cultivar Eumjinara, green domestic cultivar Sweetgreen, yellow-introduced cultivar Sunpower, and red-introduced cultivar Cheonjujeok, were compared. Yeongbohwang and Cheonjujeok had the highest total phenolic and total flavonoid contents among the six yellow and two red cultivars, respectively. The red cultivars displayed the highest DPPH and ABTS⁺ radical scavenging activities (DRSAs and ARSAs, respectively) and reducing power (RP). Among all cultivars, Cheonjujeok and Eumjinara had the highest DRSA, while both red cultivars had similar ARSAs. Among the yellow cultivars, Sinsunhwang and Yeongbohwang showed excellent DRSAs. The RP of the domestic cultivars was slightly higher than that of the introduced cultivars. Thus, the domestic cultivar Yeongbohwang exhibited excellent characteristics among the yellow cultivars, while the red cultivars Eumjinara and Cheonjujeok were similar.

염처리(electrical conductivity, EC 1.0, 4.0, 8.0 dS·m<SUP>-1</SUP>)에 따른 감자 품종들의 생장, 수량성 및 염 저항성을 이해하고자 국내외 감자 18품종을 각 처리 수준별 염상토 및 염수로 관수 재배하였다. 경, 엽, 뿌리 및 chlorophyll, 수량성, proline 함량을 조사하여 ANOVA 및 상관성을 분석하였다. 경수와 경두께는 염처리의 영향이 없었던 반면, 경장과 지상부 무게는 염에 매우 민감하였다. 특히, 지상부 무게는 대부분 품종에서 고염일수록 감소하였으나 일부 품종(‘대지’, ‘고운’, ‘하령’, ‘LT-8’)에서는 오히려 더 증가하여 품종 간 차이가 컸다. 엽수, 엽면적, 엽중은 염처리 및 품종×염의 교호작용에 의해 매우 민감한 영향을 받았으며, 뿌리 생장은 염처리 단일 요인에 대해서는 유의성이 높았으나 품종×염의 교호작용에 대한 유의성은 없었다. 총 chlorophyll과 chlorophyll a 함량은 염에 민감하였던 반면 품종×염의 영향은 없었으며, chlorophyll b는 이와 상반된 경향을 나타내었다. 괴경수, 평균괴경무게, 괴경수량 모두 염에 매우 민감하였으며, 괴경수량의 경우, ‘수미’, ‘크로다’, ‘로마나’, ‘두백’이 지상부생장이 왕성했던 품종들보다 더 양호하였다. Proline 함량은 염처리로 모든 품종에서 증가하였으며, 지상부 생장이 양호한 품종에서 함량 증가가 두드러졌다. 염 저항성 평가 지표로써 엽수, 엽면적, 엽중 및 뿌리길이는 괴경수량과 밀접한 상관성이 있어 유용할 것으로 여겨졌으나, proline 함량은 염수준이 높을수록 괴경수량과 부의 상관성이 높아 활용 지표로의 효용성이 낮았다. 결론적으로 감자 품종들 간 염 저항성은 매우 다양하였으며, 염수준이 높을수록 지상부 생장과 괴경 수량성 간 상관성이 낮아 수량이 중요한 농업적 측면에서는 염 저항성 판단 시 지상부 생장보다 상대적인 수량감소율을 활용하는 것이 더 실용적일 것으로 생각되며, ‘수미’, ‘크로다’, ‘로마나’, ‘두백’ 등이 염 저항성 감자 육성을 위한 교배재료 및 염이 문제되는 경작지에서 감자의 지속생산을 위하여 유망할 것으로 생각된다. This study evaluated the responses of 18 potato cultivars to three levels of salinity stress (electrical conductivity, EC: 1.0, 4.0, and 8.0 dS·m<SUP>-1</SUP>). Stem, leaf, root, chlorophyll, tuber yield, and proline content were investigated and statistically analyzed using analysis of variance (ANOVA) and correlations. Stem number and stem diameter were not affected by salinity, but stem length and aerial weight showed highly significant responses to salinity. Aerial weight decreased with increasing salinity levels in most cultivars, while it increased in some the cultivars ‘Daejima’, ‘Goun’, ‘Haryeong’, and ‘LT-8’. Leaf number, leaf area index, and leaf weight were most significantly affected by salinity and the cultivar × salinity interaction. Root length, root weight, total chlorophyll and chlorophyll a were affected by salinity, but not by the cultivar × salinity interaction. The opposite trend was shown in chlorophyll b. Although there was great variability among cultivars, tuber yield decreased in all cultivars, and was most significantly influenced by salinity and the cultivar × salinity interaction. ‘Superior’, ‘Kroda’, ‘Romana’, and ‘Duback’ gave better tuber yields under salinity at EC 4.0 and 8.0 dS·m<SUP>-1</SUP> than the cultivars with better aerial weights. Proline content was increased by salinity in all cultivars, and was more remarkable in the cultivars with better aerial weights than in cultivars such as ‘Superior’ and ‘Kroda’ with better tuber yields. Leaf number, leaf area index, leaf weight, and root length parameters were considered to be useful criteria in the evaluation of salt tolerance because of their high positive correlation with tuber yield; however, given its negative correlation with tuber yield under high salinity, proline content was not. Salinity tolerances varied greatly among potato cultivars. The low correlation between growth and yields of aerial parts under high salinity suggests that, in commercial agriculture, it might be more practical to compare relative yields to controls. Additionally, ‘Superior’, ‘Kroda’, ‘Romana’, and ‘Duback’ might be very useful cultivars to use in breeding programs to develop salinity-tolerant potatoes, as well as for sustainable potato production in saline areas.

An experiment was carried out at the Agronomy Field Laboratory, Bangladesh Agricultural University (BAU), Mymensingh in Old Brahmaputra Alluvial Flood Plain (AEZ-9) during December 2005 to May 2006 to examine the root growth of different rice cultivars under various establishment methods. This experiment comprised two sets of treatment (i) three methods of planting viz., dry direct seeding, wet direct seeding and transplanting, and (ii) six rice cultivars, two inbreds viz., BRRI Dhan 28 and BRRI Dhan 29, two hybrids, viz., Aalok 6201 and Sonarbangla 1 and two local improved cultivar viz., Habigonj IV and Habigonj VIII. Cultivars had more remarkable effect on different root parameters i.e. number of roots, root length, root length density, root biomass, root weight ratio and root shoot ratio of hybrid, inbred and local improved rice cultivars than method of planting. BRRI Dhan 28 performed the best for most of the parameters. At harvest, BRRI Dhan 29 showed the best rooting behavior among the cultivars. For both stages hybrid rice cultivars showed intermediate and local improved cultivars performed lower in rooting behavior. Direct seeding method performed better than transplanting method for most of the root parameters but wet direct seeding and dry direct seeding methods were identical. Interaction effect between method of planting and cultivar in most of the root parameters were insignificant. But, BRRI Dhan 28 and BRRI Dhan 29 under wet direct seeding method and Sonarbanngla 1 under transplanting method showed the best rooting performance among the other combinations.
