We collected 32 maize inbred lines from eastern cereal and oilseed research center in Canada to develop new maize varieties. We also evaluated genetic diversity, genetic relationships, and population structure using 35 SSR markers. A total of 269 alleles were revealed in 35 loci with an average of 7.69 and a range between 3 and 15 alleles per locus. The genetic diversity values varied from 0.176 to 0.889 with an average of 0.691. The polymorphic information content varied from 0.171 to 0.879 with an average of 0.659. Population structure analysis indicated that 32 Canadian maize inbred lines comprised four major groups and one admixed group based on a membership probability threshold of 0.80. The four major groups contained 13, 2, 5 and 2 maize inbred lines, respectively. From genetic relationships analysis, the all inbred lines were divided into three main groups at 26% genetic similarity. Group I included 22 inbred lines, and Group II included 9 inbred lines. Group III consist of only one inbred line. The results in this study would be useful for the improvement and development of new cultivars, planning crosses for hybrids or development of inbred line in maize breeding program

A new lettuce (Lactuca sativa L.) variety ‘Sunny Red Butter’ that belongs to butter-head type has transverse broad elliptical leaf with red color. Crossbreeding of ‘Oriana’ and ‘Cardinale’ was made to obtain seeds of the F1 generation. Subsequent generations were selected using in pedigree methods until 2011, resulting in ‘Sunny Red Butter’. The new variety ‘Sunny Red Butter’ is brown in seeds and the upper part of the leaf is light red and glossy. The leaf stalk is white. It can be harvested from 30 days after planting. The average harvested leaf number is 51 leaves per plant. The average weight is 556.5g per plant, which is 44% higher than a control lettuce variety ‘Germania’. It showed that 30.9 tons/ha production was made in spring, summer, and autumn cultivations for 3 years in 6 areas (Daegwanryeong, Gyeonggi, Chungbuk, Jeonbuk, Gyeongnam, and Jeju) than the control variety ‘Germania’. The shelf-life of ‘Sunny Red Butter’ was 4 weeks for storage at 4°C. Anthocyanin amount (10.3 mg/100g) of ‘Sunny Red Butter’ was lower than that of ‘Germania’. BSL (latucin+8-deoxylactucin+lactucopicrin) amount of ‘Sunny Red Butter’, the bitter ingredients was 26.1 μg/g and higher than BSL amount of ‘Germania’. Leaf hardness of ‘Sunny Red Butter’ was 1,554 kg/cm 2 , which was thicker than ‘Germania’. ‘Sunny Red Butter’ showed better taste (more crispy and sweeter) than ‘Germania’. The new variety ‘Sunny Red Butter’ can be used as lettuce productions during spring and autumn in most area and in summer in highland of Korea.

‘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.

A new peanut variety ‘Heuksaeng’(Arachis hypogaea ssp. hypogaea L.) was developed at the Department of Southern Area Crop Science, National Institute of Crop Science (NICS) in 2014. This was developed from the cross between ‘Iksan 31’ with Virginia typed short stem and ‘Iksan 35’ with large grain. ‘Heuksaeng’ is the first purple testa variety developed in Korean. It has 25 branches per plant and its length of main stem was 32 cm. Each pod has two grains with puple testa and long ellipse-shaped kernel. Its yield components showed 60 pods per plant, 69 g of 100-seed-weight and 77% of pod shelling ratio in the regional yield trials (RYT). Seed quality showed 46.0% of crude oil and 26.9% of protein content. This variety has anthocyanins typed as delpinidin-3-glucoside (D3G) and cyanidin-3-glucoside (C3G) in seed testa. This variety showed more resistant to late leaf spot, web blotch, and lodging, compared to reference variety. In the regional yield trials for 2 years, ‘Heuksaeng’ with 4.25 MT/ha for grain production has the same productivity to reference variety.

: ‘Jungmo2501’ ( Avena sativa L.), a winter oat for forage use, was developed by the breeding team at the National Institute of Crop Science, RDA in 2010. The following is the characteristics of ‘Jungmo2501’ that is characterized as light green leaf, yellow brown culm and whitish yellow grain. The heading date of ‘Jungmo2501’ was about 3 days earlier than that of check cultivar ‘Samhan’(May 7 and May 10, respectively). Its plant height was 11 cm longer than 103 cm of the check, and the leaf blade ratio of aerial parts was 26 % higher than the check (11.8% and 9.4%, respectively). The cold tolerance, resistance to lodging and wet injury of ‘Jungmo2501’ were similar to those of the check. The average forage dry matter yield of ‘Jungmo2501’ harvested at milk-ripe stage was 5% higher than the check (15.5 ton ha -1 and 14.7 ton ha -1 , respectively). ‘Jungmo2501’ was higher than the check in terms of protein content (6.6% and 5.9%, respectively), neutral detergent fiber (58.5% and 57.6%, respectively), and acid detergent fiber (34.5% and 32.1%, respectively), while total digestible nutrients was lower than the check (61.6% and 63.6%, respectively), and TDN yield was 0.37 ton ha -1 more than that of the check (9.71 ton ha -1 and 9.34 ton ha -1 , respectively). The silage grade of ‘Jungmo2501’ estimated by Flig score showed level Ⅱ , meaning good quality. Fall sowing cropping of ‘Jungmo2501’ is recommended only for areas where average daily minimum mean temperatures in January are higher than － 6°C.

Wheat is one of major crop and wheat flour is used to various end-use products such as bread, cookies and noodles due to its unique characteristic of it as elasticity and viscosity. Wheat consumption has been generally increasing in not only US and Europe but also Korea. Nevertheless, gluten proteins in wheat endosperm are cause of allergy by food ingestion. Hence, studies on the allergy have been conducting and have been attracting public attention. Herein, we report studies on research trend of the issue with research papers over the last decade for suggestion of future research direction. Since 2012, studies on allergy of gluten proteins have been dramatically increased based on the number of published papers related to the issue. As results of research activities by country, the Europe accounted for 60% corresponding to the number of papers. Next US (13%), Japan (9%), China (5%), and Korea (2%) came. In Korea, studies on allergy of gluten protein are less studied. In the field of studying of gluten allergy, there are two major technologies as preclinical technology and genome research accounted for 58% and 26%, respectively. In Korea, the study on glutenin proteins which is closely related to wheat allergy is actively performed. Therefore, it can be expected that research will be become more active.

: This study was executed to establish a basis of evaluation of starch properties of Korean wheat cultivars e.g. damaged starch, swelling, and pasting properties for Korean wheat breeding program. Damaged starch is critical evaluation factor for flour milling related industry because it influences water absorption and color of dough for processing quality and preference of end-use products. The present results revealed that there was significantly high positive correlation between the results of damaged starch analysis by amperometric (SD-matic) and enzymatic (Megazyme assay) methods. Evaluation of damaged starch must be considered as one factor to evaluate properties of starch due to its accuracy and a stable efficiency for the wheat breeding program. Properties of swelling and pasting of dough were important for cooking time and texture. Nevertheless, it was impossible to evaluate starch extracted from flour in the wheat breeding program i.e. small amount of flour or small number of spikes Comparison of results of evaluation of properties of swelling and pasting with starch or flour, the evaluation using flour positively correlated with the other evaluation using starch. In addition, swelling evaluation must be considered to apply for the wheat breeding program because the result of evaluation of swelling property, which possible to evaluate with low efficiency, and the quantity of a sample is highly under positive correlation with paste peak viscosity. In the future, studies using NIR (Near Infrared) analysis must be necessary to evaluate starch properties with grains in early generation lines for improvement of wheat breeding program.

The present results revealed that there was significantly high positive correlation between the results of damaged starch analysis by amperometric (SD-matic) and enzymatic (Megazyme assay) methods. Evaluation of damaged starch must be considered as one factor to evaluate properties of starch due to its accuracy and a stable efficiency for the wheat breeding program. Properties of swelling and pasting of dough were important for cooking time and texture. Nevertheless, it was impossible to evaluate starch extracted from flour in the wheat breeding program i.e. small amount of flour or small number of spikes Comparison of results of evaluation of properties of swelling and pasting with starch or flour, the evaluation using flour positively correlated with the other evaluation using starch. In addition, swelling evaluation must be considered to apply for the wheat breeding program because the result of evaluation of swelling property, which possible to evaluate with low efficiency, and the quantity of a sample is highly under positive correlation with paste peak viscosity. In the future, studies using NIR (Near Infrared) analysis must be necessary to evaluate starch properties with grains in early generation lines for improvement of wheat breeding program.","PeriodicalId":448090,"journal":{"name":"Korean Journal of Breeding","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128774704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mixolab is suitable to evaluate mixograph and farinograph for testing dough rheology and amylopgraph for properties of starch pasting with a view to analyze protein and starch quality at the same time. Mixolab analysis revealed that water absorption and dough development time of Korean wheat cultivars were similar to it of soft wheats and flour while dough stability and protein weakening of Korean wheat cultivars were similar to it of hard wheat and strong flour. Also, starch properties of Korean wheat cultivars showed similar properties of hard wheats. There was a significantly positive correlation between mixolab and mixograph in the water absorption of dough, whereas no correlation was observed between them in dough development time and stability. Furthermore, maximum viscosity of starch and breakdown in amylopgraph were correlated to stabilities of pasting and cooking and setback in mixolab. Resultantly, in mixolab, properties of dough and protein highly and positively correlated to loaf volume, hardness of noodles, and size of cookies i.e. diameter. Moreover, positive correlation was identified between viscoelasticity of noodles and properties of protein, pasting, and setback in mixolab.

A new Rehmannia glutinosa cultivar ‘Tokang’ was derived from ‘Jihwang 1’ seedlings by medicinal crop breeding team of National Institute of Horticulture and Herbal Science, RDA in 2009. It has pink flower, dark brown seed coat, light yellow root cortex. The plant type was some rising from the ground. The content of catalpol and extract were higher than the ‘Jihwang 1’(check variety). The content of catalpol was 4.55% and the extract was 71.2%. It showed stronger resistance to root rot compare with the ‘Jihwang 1’. The regional yield trials were conducted at three different locations from 2007 to 2009. The average yield of ‘Tokang’ was 21.1ton/ha, which was 12% more than the ‘Jihwang 1’. This cultivar is adaptable to the whole of Korea except for mountain areas. (Registration No. 4725)
