양안옥은 다수성 사료용 옥수수 품종 개발을 목표로 2012년에 농촌진흥청 국립식량과학원에서 자식계통 KS164과 KS163을 교잡하여 육성한 다수성 단교잡종이다. 양안옥의 종피색은 황오렌지색이며 입질은 중간종이다. 양안옥은 2007~2008년 동안 생산력검정시험을 거쳐, 2009~2012년까지 3년간 4지역에서 지역적응시험을 실시하였다. 그 결과 우수성이 인정되어 2012 농작물 직무육성 신품종으로 결정되었고 양안옥으로 명명하였다. 양안옥의 출사일수는 대비 품종인 광평옥보다 2일 빠르다. 간장은 광평옥과 유의한 차이는 없으나 착수고율은 광평옥보다 높고 도복은 광평옥과 비슷한 정도로 강하며 후기녹체성과 이삭비율도 광평옥과 유의한 차이는 없다. 양안옥의 깨씨무늬병은 광평옥과 비슷한 중강의 저항성을 보이며, 그을음무늬병도 광평옥과 같이 강한 편이다. 검은줄오갈병, 이삭썩음병 및 조명나방도 광평옥과 같이 중 정도의 저항성을 보인다. 양안옥의 건물수량은 17.45 톤/ha이며, TDN수량은 11.96 톤/ha로 광평옥과 유의한 차이는 없었다. 양안옥의 종실수량은 8.32 톤/ha로 장다옥과 유의한 차이는 없었다. 4 : 1 (모본 : 부본) 재식비율로 동시 파종하여 채종 시험한 결과 모본의 출사기와 부본의 화분비산기간이 일치하며 채종수량은 1.79 톤/ha이었다. 양안옥은 전국적으로 재배가 가능하다. Yanganok, a new single cross variety, was developed by the maize breeding team at the National Institute of Crop Science (NICS), RDA in 2012. This hybrid, which has a high yield of grain was produced by crossing two inbred lines, KS164 and KS163. KS164 is the seed parent and KS163 is the pollen parent of Yanganok. It is a yellow-orange intermediate maize hybrid (Zea mays L.). After a preliminary yield trial and advanced yield trial of Yanganok (Suwon180) in Suwon for 2 years, a regional yield trial was carried out for its growth characteristics, and yields were determined at 4 different locations from 2009 to 2012, with the exception of 2010. It was named 'Yanganok'. The silking date of Yanganok is 2 days earlier than that of the check hybrid, Kwangpyeongok. Plant height of Yanganok is similar to Kwangpyeongok, but its ear height ratio is higher than that of Kwangpyeongok. It has resistance to lodging. Stay-green features of Yanganok are similar to those of Kwangpyeongok. The ear ratio of Yanganok is similar to Kwangpyeongok. It has moderate resistance to southern leaf blight (Bipolaris maydis) and strong resistance to northern leaf blight (Exserohilum turcicum). It has moderate resistance to black streaked dwarf virus (BSDV), ear lot and corn borer. The dry matter yield of Yanganok, 17.45 ton/ha, was similar to that of Kwangpyeongok. The total digestible nutrients (TDN) yield of Yanganok, 11.96 ton/ha, was similar to that of Kwangpyeongok. The grain yield of Yanganok, 8.32 ton/ha was similar to that of Jangdaok. Seed production of Yanganok went well due to a good match during crossing between the seed parent, KS164, and the pollen parent, KS163, in Yeongwol, and F1 seed yield was 1.79 ton/ha. Yanganok would be a suitable cultivar to all plain areas in the Korean peninsula.

손범영,이영호,이석하 韓國作物學會 2006 Korean journal of crop science Vol.51 No.3

본 연구는 콩의 초기 유묘생육기간 동안의 lipoxygenase가 결여된 진품콩, 진품콩 2호와 정상적인 태광콩의 lipoxygenase 활성 변화를 비교 검토하여 알아보기 위하여 실시하였다. Lipoxygenase 결여 콩 품종의 초기 생육 및 lipoxygenase 활성 변화에서 유묘의 생체중은 진품콩 2호와 태광콩이 진품콩 보다 증대되는 경향이었고 하배축의 길이는 진품콩과 진품 콩 2호가 태광콩보다 서서히 증가하였지만 하배축의 두께는 진품콩과 진품콩 2호가 태광콩보다 두껍게 증가하는 경향이었다. 자엽의 lipoxygenase 활성 변화는 유형 I lipoxygenase 활성에서 진품콩과 태광콩이 계속 감소하는 경향이었지만 진품콩 2호는 활성이 나타나지 않았다. 유형 II lipoxygenase 활성에서 태광콩은 발아 2일째부터 계속 증가하다가 발아 4일 째에서 5일째 사이에 최대의 활성이 나타났고 발아 5일째부터 다시 감소하는 경향이었다. 하배축의 유형 I lipoxygenase 활성에서는 진품콩과 태광콩이 발아 l일째부터 급격히 감소하였다. 하배축의 유형 II lipoxygenase 활성은 3 품종 모두 나타나지 않았다. Three lipoxygenase isozymes in soybean seeds are thought to be a major contributor to lipid peroxidation and generation of free radicals which may result in seed deterioration. This study was conducted to get the basic information for changing lipoxygenase activity during seed germination in lipoxygenase-lacking soybeans. Fresh weight of soybean seedling of Jinpumkong 2 and Taekwangkong increased more rapidly than that of Jinpumkong. Hypocotyls of Jinpumkong and Jinpumkong 2 were longer and thicker than that of Taekwangkong. Type I lipoxygenase activity (pH 9.0) in cotyledon of Jinpumkong lacking lipoxygenase-2, 3 showed higher than that of Taekwangkong, and Type I lipoxygenase activity of two cultivars decreased continually. On the other hand, Type II lipoxygenase activity of Taekwangkong began to increase continually two days after germination, reached to the maximum between 4 days and 5 days, and began to decrease continually five days after germination. Type I and II lipoxygenase activity in hypocotyls was not detected in all soybean cultivars.

This study evaluated the productivity of early maturity silage corns during continuous monocropping and the possibility of expanding forage production. Continuous monocropping of three silage corns, such as Kwangpyeongok (medium maturity), Sinhwangok (early maturity), and Sinhwangok2 (early maturity) was planted twice, in April and July from 2018 to 2019 at Suwon. The number of days from the sowing date to the silking date was 78 for the preceding crop and 52 for the succeeding crop. The number of days from the silking date to the harvesting date was 26 for the preceding crop and 46 for the succeeding crop. The sums of the temperature from the sowing date to the silking date were 1,512℃ for the preceding crop, 1,246℃ for the succeeding crop. The sums of the temperature from the sowing date to the harvesting date were 2,198℃ for the preceding crop and 1,951℃ for the succeeding crop. The dry matter yield of the preceding crop (1,637 kg/10a) was similar to that of the succeeding crop (1,565 kg/10a). The dry matter yields of Sinhwangok2 (1,673 kg/10a), Sinhwangok (1,660 kg/10a) and Kwangpyeongok (1,579 kg/10a) were similar to those of the preceding crop. The dry matter yields of Sinhwangok (1,669 kg/10a) and Kwangpyeongok (1,651 kg/10a) were similar to those of the succeeding crop and Sinhwangok2 (1,374 kg/10a) was the lowest among the three corn varieties. The total digestible nutrients (TDN) yield of the preceding crop (1,135 kg/10a) was similar to that of the succeeding crop (1,037 kg/10a). The TDN yields of Sinhwangok2 (1,183 kg/10a), Sinhwangok (1,158 kg/10a), and Kwangpyeongok (1,063 kg/10a) were similar to those of the preceding crop. The TDN yields of Sinhwangok (1,150 kg/10a) and Kwangpyeongok (1,100 kg/10a) were similar for the succeeding crop and Sinhwangok2 (970 kg/10a) was the lowest among the three corn varieties. The total dry matter yields of Sinhwangok (3,329 kg/10a) and Kwangpyeongok (3,230 kg/10a) were similar, but Sinhwangok2 (3,047 kg/10a) was the lowest among the three corn varieties. The total TDN yields of Sinhwangok (2,307 kg/10a), Kwangpyeongok (2,162 kg/10a), and Sinhwangok2 (2,152 kg/10a) were similar. It was concluded that Sinhwangok and Sinhwangok2 have high TDN yields as well as early maturity, and therefore are advantageous for direct continuous monocropping.

F2 종실의 포화지방산의 함량은 17.6%로 F1 종실과는 비슷하였으나, 자식계통보다는 낮았다. F2 종실의 불포화지방산의 함량은 82.4%로 F1 종실과는 비슷하였으나, 자식계통보다는 높았다. 3. F2 종실의 leucine의 함량이 자식계통 및 F1 종실보다 낮았다. 반면 F2 종실의 valine, serine, threonine, cysteine, aspartic acid, lysine, arginine, histidine 등의 함량이 자식계통 및 F1 종실보다 높았다. Alanine 등 나머지 아미노산은 자식계통, F1 종실, F2 종실간 조성변이가 비슷한 경향이었다. 4. 산성아미노산인 MMA(monoamino monocarboxylic acid)가 자식계통, F1 종실, F2 종실에서 그 조성 비율이 가장 높았으며 산성 아미노산인 DMA(diamino monocarboxylic acid), 방향족 아미노산인 AAA(aromatic amino acid) 순으로 조성비가 높았다. This study was carried out to evaluate the quality properties, fatty acid composition and amino acid composition of major Korean inbred lines and hybrids of maize for corn breeding. Protein content of F2 seeds was 9.0%, which was slightly lower than those of inbred lines, 11.4%, and F1 seeds, 10.9%. in hybrid maizes. Lipid content of F2 seeds of hybrid maizes was 4.2%, slightly higher than those of inbred lines, 3.3%, and F1 seeds, 3.6%. However, there was no significant difference in ash content. The amount of linoleic acid in inbred lines, F1 and F2 seeds of hybrid maizes was highest among all fatty acids and followed by oleic acid, palmitic acid, stearic acid and linolenic acid. The composition of saturated fatty acid of F2 seeds was 17.6%, similar to F1 seeds but it was lower than that of inbred lines. The composition of unsaturated fatty acid of F2 seeds was 82.4%, similar to F1 seeds but was higher than inbred lines. The content of leucine of F2 seeds was lower than inbred lines and F1 seeds. The content of valine, serine, threonine, cysteine, aspartic acid, lysine, arginine, histidine of F2 seeds was higher than inbred lines and F1 seeds. MMA (monoamino monocarboxylic acid) in inbred lines, F1 and F2 seeds of hybrid maizes was highest among all amino acids and followed by DMA (diamino monocarboxylic acid) and AAA (aromatic amino acid).

‘Sinhwangok’, a new maize F1 hybrid (Zea mays L.), is developed by the maize breeding team at the National Institute of Crop Science (NICS), RDA in 2015. The high-yielding hybrid, named ‘Sinhwangok’ was bred by crossing between two inbred lines, ‘KS178’ and ‘KS145’. It is a yellow dent maize hybrid. After advanced yield trial of ‘Sinhwangok’ in Suwon for two years, regional yield trial was subsequently carried out for evaluation of its growth and yield at three different locations from 2012 to 2015. The days to silking of ‘Sinhwangok’ are 74. The plant height of ‘Sinhwangok’ is 241cm, similar to ‘Jangdaok’, and its ear height ratio is 51%, similar with that of ‘Jangdaok’. It has resistance to lodging. The number of ear per 100 plants is 96. The ear length of ‘Sinhwangok’ is 17cm, shorter than that of ‘Jangdaok’. The weight of 100 seeds of ‘Sinhwangok’ is 34.1g, similar to that of ‘Jangdaok’. It has moderate resistance to southern leaf blight (Bipolaris maydis). It has moderate resistance to European Corn Borer (Ostrinia nubilalis). The grain yield (8.9 ton/ha) of ‘Sinhwangok’ was 15% higher than that of ‘Jangdaok’. The seed production of ‘Sinhwangok’ was acceptable due to a good synchronization of flowering period during crossing between the seed parent, KS178, and the pollen parent, KS145, in Yeongwol and F1 seed yield was 2.3 ton/ha. ‘Sinhwangok’ would be a suitable cultivar to all plain area in Korea.
