'Hwangkeumnuri' is a japonica rice variety developed and registered by the rice breeding team of Honam Agricultural Research Institute, NICS, RDA in 2006. This variety was derived from a cross between 'Milyang 165' (Junambyeo) with good quality and high yield and HR14732-B-67-2-3 with multi-disease resistance. This variety has about 125 days growth duration from transplanting to harvesting in west-southern coast, Honam and Youngnam plain of Korea. It is about 76 cm in culm length and tolerance to lodging. In reaction to biotic and abiotic stresses, it shows resistance to blast, bacterial blight pathogen from $K_1$ to $K_3$ and stripe virus, but susceptible to other major diseases and insect pests. The milled rice of 'Hwangkeumnuri' exhibits translucent, relatively clear non-glutinous endosperm and midium short grain. It has similar amylose content of 18.9% and lower protein content of 6.2%, and good palatability of cooked rice compared with 'Nampyeongbyeo'. The milled rice yield performance of this variety is about 5.74 MT/ha in local adaptability test for three years. 'Hwangkeumnuri' would be adaptable to west-southern coast, Honam and Yeongnam plain of Korea.

A new vegetable peanut cultivar "Charmwon" (Arachis hypogaea ssp. fastigiata.L.) was developed at the Yeongnam Agricultural Research Institute, NICS, in Milyang 2006. It was developed from the cross between the disease resistant cultivar "HYQ(CG)S-10" and the high-yielding cultivar "Sinkwang". "Charmwon" which has been classified as Shinpung plant type is less branch number with early flowering and ellipse-shaped large kernel. Each pod which showed very shallow constriction had two grains with red testa and 100 seed weight was 90g in the regional yield trials (RYT). This variety also showed higher free sugar and protein contents in seed quality, and had more resistant to early and late leaf spot diseases compared with check one. In the regional yield trials "Charmwon" was out-yielded than check variety by 18% with 8.93 ton/ha for fresh pod and by 4% with 3.95 ton/ha for grain.

To evaluate growth habits, fresh pod yield potential, and possibility of early and late seeding, seeding dates were extended from March 21 to June 20 by PE mulching and non-mulching. Soil temperature, under 5cm from surface, above 15$^{\circ}C$ at 10 a.m. in early seeding reached about March 25 in mulching and April 5 to April 12 in non-mulching. Days to emergence and first flowering were accelerated owing to increasing temperature, as seeding was delayed. Days to emergence according to seeding dates reduced 21 to 8 day in mulching and 33 to 10 day in non-mulching. Days to flowering were ranged from 51 to 26 day in mulching and from 69 to 32 day in non-mulching and differences between mulching and non-mulching on each seeding date had 18 to 4 days. Early seedings till April 21 had 160-170 flowers per plant for 8 weeks, while late seedings from May 21 increased more speedily with 200 flower for 6 weeks. Harvesting of fresh peanut, at 80 days after first flowering, was possible from Aug. 1 to Oct. 7 (133-108 days to harvest) by mulching and from Aug. 19 to Oct. 12 (151 to 114 days) by non-mulching. Yields between mulching and non-mulching in early seeding until April 21 had more difference, but in late seeding after May 21 was higher and showed insignificance. Pod setting periods by early and late seeding were about 3 weeks equally. In late seeding pod setting were almost concentrated for front 15 days. In spite of difference of fresh pod weight between two seeding times, the distributions of average of seed weight showed nearly same tendency.

This study researched a document regarding 'Pyeon (tteok)' on 25 Jong-ga ancestral ritual foods through "Jong-ga Ancestral ritual formalities and food", published during 2003~2008 by the National Research Institute of Cultural Heritage of Cultural Heritage Administration. A after about 10 years, the transmission process of the setting and recipe was compared and analyzed in 2015 by directly visiting 4 Jong-ga. This research classified regions into 7 Gyeonggi, 4 Chungcheong, 2 Honam, and 12 Yeongnam, and classified hakpa, Gyeonggi, Chungcheong, Honam region into 13 Gihohakpa, Yeongnam region into 12 Yeongnamhakpa. The important analysis standard of Jong-ga ancestral ritual food was the region and hakpa, which appeared to considerably influence 'Pyeon' setting style, which represents and symbolizes family and recipe. Gihohakpa Jong-ga, which is an academic tradition that pursues practical interests, seems to highly regard practicality to adapt to changes along with the period. On the contrary, Yeongnamhakpa Jong-ga, which highly regards self-sufficiency living base and moral justification, seems to be highly conservative. Increase in Jong-ga, which utilizes mill, is the result of adaptation to the period environment such as Jongbu aging and lack of labor, etc.

The objectives of this study were to investigate soil chemical and microbiological characteristics in Yeongnam, Honam, Chungcheong and Kangwon for forest rehabilitation and management in abandoned coal mine areas. Average soil pH was 5.5 (4.2 ~ 8.1). Average contents of TOC, total N and available P2O5 were 1.1% (0.1 ~ 2.6%), 0.08% (0.02 ~ 0.14%) and 16.1 ppm (3.4 ~ 63.1 ppm), respectively. Average CEC was 3.4 $cmol_c\;kg^{-1}$ and total no. of bacteria1 showed $4.9{\times}10^{12}CFU\;g^{-1}$. According to areas, soil pH was the highest in Kangwon (6.1), and Yeongnam (5.7), Honam (5.3) and Chungcheong (4.7), respectively. TOC and total no. of bacteria showed no difference. Total-N was higher in order of Yeongnam (0.10%) > Chungcheong (0.08%) = Honam (0.07%) > Kangwon (0.06%), while Av. $P_2O_5$ Yeongnam (23.9 ppm) = Chungcheong (24.5 ppm) > Honam (10.9 ppm) = Kangwon (4.9 ppm). Yeongnam showed higher value in CEC (17.5 $cmol_c\;kg^{-1}$) than any other areas. Generally, soil characteristic of Yeongnam was better for vegetation growth than any other areas, while Kangwon was worse. According to elapsed time from forest rehabilitation, patterns of soil pH and CEC showed decrease according to time while TOC and total-N increased. There were no significant differences in Av. $P_2O_5$ and total no. of bacteria. Soil chemical characteristics in abandoned coal mine areas were disadvantageous for vegetation growth in comparison with general forest soils. Therefore, sustainable managements such as fertilization are necessary for good rooting and growth of vegetation.

A new peanut variety "Pungsan" (Arachis hypogaea ssp. hypogaea L.) was developed at the Yeongnam Agricultural Research Institute, NICS, in Milyang in 2007. It was derived from a cross between a short stem cultivar "Satonoka" and a high-yielding local cultivar "Yecheon". "Pungsan" is the Virginia plant type. It has 18 branches per plant and 40 cm of main stem height. Each pod with long-ellipse shaped large kernel has two grains with light-brown testa and 100 seed weight was 95g in the regional yield trials (RYT). "Pungsan" showed more resistant to web blotch compared with check variety. In the regional yield trials "Pungsan" was outyielded in grain yield to the check variety by 16% with 4.45 MT/ha for grain.

Many important traits have been tagged allowing plant breeders to apply marker assisted selection (MAS) in rice. PCR itself is simple to set up, and requires little hands-on time. However, a crucial limiting step of MAS programs is the reliable and efficient extraction of DNA which can be performed on thousands of individuals. In this study, We describe a modification of the DNA extraction method, in which cetyltrimethylammonium bromide (CTAB) is used to extract DNA from leaf tissues for suitable MAS in rice. We followed the standard 2% CTAB extraction method in all the procedure. In addition we used the 1.2 ml 8-strip tube instead of 1.5 ml E-tubes to fit the 8-multichannel pipette and employ the 96 well plate to use the swing bucket centrifuge. Our modified CTAB DNA extraction method offers several advantages with respect to traditional and simple methods. 1) adult leaf samples collected in paddy field are applicable. 2) 96 leaf samples can be homogenized only one-time by using tungsten carbonate bead and 96well block. 3) semiautomatic loading method using 8-multichannel pipette from DNA extraction to electrophoresis of PCR products. 4) our system can extract about 400 leaf samples per day by only one technicion. Therefore, this method could be useful for marker assisted breeding in rice.
