김동관,손동모,천상욱,이경동,임요섭 한국자원식물학회 2009 한국자원식물학회지 Vol.22 No.2
2,500여 녹두 유전자원 중에서 작물학적 가치를 가진 789계통을 선발하고, 2005년과 2006년에 각각 401, 388 계통을 대상으로 배축색, 엽 크기 등 27가지 형질특성을 조 사하고 종실의 vitexin과 isovitexin 함량을 분석하였다. 2005년 시험에 이용된 401계통의 평균 vitexin과 isovitexin 함량은 각각 8.7(1.1~13.4), 9.5(0.9~15.9) mg/g이고, vitexin과 isovitexin 함량의 상관계수(R2)는 0.958었으 며, VC3890B 등 vitexin과 isovitexin 고 함유 자원 9계 통을 선발하였다. 2006년 시험에 이용된 388계통의 평균 vitexin과 isovitexin 함량은 각각 10.2(2.0~15.9), 10.6 (0.6~17.6) mg/g이고, vitexin과 isovitexin 함량의 상 관계수(R2)는 0.958었으며, VC 4096-2B-4-B-2-B 등 vitexin과 isovitexin 고 함유 자원 6계통을 선발하였다. 녹두 주요 형질 중에서 엽이 클수록, 등숙기간이 길수록 vitexin과 isovitexin 함량이 많은 경향이었다. In this study, the selected 789 lines having agronomic values out of over 2,500 mungbean (Vigna radiata (L.) Wilczek) germplasms, examined the 27 characters including hypocotyl color and leaf size of 401 lines in 2005 and of 388 lines in 2006, and analyzed the contents of vitexin and isovitexin in these mungbean germplasms. The average contents of vitexin and isovitexin in mungbean of the 401 lines used in 2005 were 8.71(1.1~13.4) and 9.54(0.9~15.9) ㎎/g, respectively, and the correlation coefficiency (R2) of the contents of vitexin and isovitexin was 0.958. Nine lines including VC3890B were selected to be the ones containing high vitexin and isovitexin. The average contents of vitexin and isovitexin in mungbean of the 388 lines used in 2006 were 10.17(2.0~15.9) and 10.64(0.2~17.6) ㎎/g, respectively, and the correlation coefficiency (R2) of the contents of vitexin and isovitexin was 0.958. Six lines including VC4096-2B-4-B-2-B were selected to be the ones containing high vitexin and isovitexin. The contents of vitexin and isovitexin were higher in the mungbean with larger leaves and longer ripening period out of the main characters.

This study was conducted to improve of major characteristics and yield of sesame (Sesamum indicum L.) by different seeding time and major base nutrient. Seeding time had 2 times which were May 24th(mono-cropping system) and June 12th(sec ond-cropping system). Major base nutrients application were Magnesium sulfate, Zinc sulfate and Boron. Dry matter production of early growth state became effectively by Zinc sulfate, Boron and Magnesium sulfate application. Top dry weight of second-cropping system became effectively increasing by Magnesium sulfate and Zinc sulfate application. Capsule number per plant of mono-cropping system were higher in Boron, Mag- nesium sulfate + Zinc sulfate + Boron and Zinc sulfate + Boron application, and grains per capsule of second-cropping system were higher in Magnesium sulfate + Zinc sulfate, Zinc sulfate and Boron application. Seed yield increased 23.5% by Zinc sulfate, 22% by Magnesium sulfate + Zinc sulfate + Boron, 21% by Zinc sulfate + Boron application than control(42.2 kg /10 a) in mono-cropping system and 21.8% by Zinc sulfate, 17% by Magnesium sulfate + Zinc sulfate + Boron, 16% by Boron ap- plication than control (22.9 kg /10 a) in second-cropping system.

To calculate proper seismic design load and seismic design category, the exact site class for construction site is required. At present, the average shear-wave velocity for multi-layer soil deposits is calculated by the sum of shear-wave velocities without considering of vertical relationship of the strata. In this study, the transfer function for the multi-layered soil deposits was reviewed on the basis of the wave propagation theory. Also, the transfer function was accurately verified by the finite element model and the eigenvalue analysis. Three methods for site period estimation were evaluated. The sum of shear-wave velocities underestimated the average shear-wave velocities of 526 strata with large deviations. The equation of Mexican code overestimated the average shear-wave velocities. The equation of Japanese code well estimated the average shear-wave velocities with small deviation.

A new mung bean cultivar, Vigna radiata (L.) R. Wilczek ‘Samhwang’, was derived from a cross between ‘Samgang’ and‘KM9901-3B-15-2-4’ obtained in 2006 and developed at the Jeollanamdo Agricultural Research and Extension Services (JARES) in 2014. ‘Samhwang’ has an erect growth habit, lobed leaflets, green hypocotyls, light yellow corolla, and a dull yellow seed surface. Its stem lengthwas 64 cm, 5 cm shorter than that of the control cultivar ‘Owool’. The 1000-seed weight was 53 g, i.e., 4 g heavier than that of ‘Owool’. ‘Samhwang’ exhibited similar field resistance to mung bean mottle virus, cercospora leaf spot, powdery mildew, and lodging when comparedwith that of the control cultivar. The sprout yield ratio and hard seed rate were the same as those of ‘Owool’. The average seed yield of‘Samhwang’ was 1.76 ton/ha, which was 14% greater than that of ‘Owool’ (Registration No. 5877).
