Hyeon Gui Moon(文賢貴),Bong Ho Choe(崔鳳鎬),Keun Yong Park(朴根龍) 한국육종학회 1985 한국육종학회지 Vol.17 No.2

Eight corn inbreds and their 28 F₁’S were used to study the inheritance of resistance to maize dwarf mosaic virus (MDMV) in Korea. Corn plants were inoculated with MDMV strain B at 4 leaf stage (23 days after emergence) and two MDMV ratings were made at 29 days and 58 days (15 days after silking) after inoculation, respectively. No differences were observed between the two rating times in the resistance for both inbreds and hybrids, the effects of combining ability, the effects of dominance and the dominance order of inbreds in Vr, Wr graphs for MDMV. Inheritance of resistance to MDMV appeared to be influnced by both additive and dominant gene effects, but additive effect was more important. Partial dominance without interactions among non-allelic genes was also recognized. Inbred B 68 showed the greatest general combining ability effect for MDMV resistance and Ga 209 and H 92 were followed in that order. B 68 was appeared as the most promising gene source for MDMV resistance.

Chalok3, a new waxy corn hybrid was developed at the National Crop Experiment Station, RDA in 2001. It is a single cross hybrid, which was crossed between KW35 as a seed parent and KW7 as a pollen parent. Chalok3 was 73 days in days to silking and eight days later than Chalok1. Plant height of Chalok3 was 215cm and taller than that of Chalok1. Chalok3 was 4.2cm longer than Chalok1 as 20.2cm in ear length, but shorter in ear diameter. The ratio of kernel set length/ear length was 97 % and higher than other hybrids. Chalok3 was relatively resistant to Biporalis maydis (Southern leaf blight) and maize dwarf mosaic virus, and resistant to lodging. Chalok3 was compared with Chalok1 as the designation of Suwon31 at four sites for three years from 1999 to 2001. In these tests, the fresh ear weight of Chalok3 was 9.90 ton/ha and 13% higher than that of Chalok1. Chalok3 can be adapted in all over the country.

손범영,문현귀,정태욱,김시주,김종덕 韓國作物學會 2006 Korean journal of crop science Vol.51 No.3

본 시험은 사일리지옥수수의 사료가치를 향상을 위한 일환으로 최근 육성된 국내 사일리지옥수수 품종들의 사료가치를 분석하고자 수행하였다. 국내종 옥수수의 파종일에서 출사일까지의 출사일수는 수원19호의 78일에서 수원159호의 86일로 품종간에 8일간 차이가 있었고 수입종인 P3394 보다는 출사일수가 긴 것으로 나타났다. 광평옥, 청안옥, 청사옥은 도복에 강하였으며 후기녹체성은 광안옥, 광평옥, 청안옥, 청사옥, 수원159호 등은 도입종인 P3394 와 같은 수준이었다. 품종간 깨씨무늬병 저항성은 두루옥, 광평옥, 수원159호 등이 강한 것으로 나타났고, 광안옥, 수원19호, 청안옥, 장다옥, 청사옥 등은 도입종인 P3394와 비슷한 경향을 나타내었다. 그을음무늬병과 깜부기병에는 품종간 차이가 없이 강한 것으로 나타났다. 이삭비율은 청안옥이 도입종인 P3394와 같았으며, 국내종의 이삭길이는 P3394와 비슷하거나 긴 것으로 나타났다. 건물수량은 수원19호와 장다옥을 제외한 다른 품종들은 P3394와 비교해 볼 때 비슷한 것으로 나타났다. TDN은 두루옥, 광평옥, 청안옥, 청사옥 등은 P3394와 비슷하였지만 광안옥, 수원19호, 장다옥, 및 수원159호 등은 P3394 보다 낮았다. ADF는 수원159호가 가장 낮았으며, 그 외 품종들은 44.7~49.0% 로 도입종인 P3394와 비슷하였다. NDF는 두루옥이 가장 낮았으며, 두루옥을 제외한 품종들은 68.1~72.8% 로 P3394와 비슷하였다. RFV는 두루옥, 광평옥, 청안옥, 장다옥, 수원159호 등이 71.0~75.7 로 도입종인 P3394 의 70.5보다 높게 나타났으나 평균간 차이는 없었다. ADF는 출사일수, 성숙일수, 생체수량과는 유의한 부의 상관을 보였고, 조명나방의 피해율과는 유의한 정의 상관관계를 보였으며, 후기녹체성, 건물수량, TDN수량, 종실수량과는 상관이 거의 없었다. RFV는 성숙일수와 생체수량과는 유의한 정의 상관을 보였고, 조명 나방과는 유의한 부의 상관을 보였으며, 후기녹체성, TDN수량, 종실수량과는 상관이 거의 없었다. This study was conducted to evaluate growth characteristics, yield and feed value of newly bred domestic silage corn hybrids compared to foreign imported corn hybrid. Days to silking were 78~86 days and longer than that of P3394 (Control). Kwangpyeongok, Cheonganok, and Cheongsaok were resistant to lodging. Such trait of stay-green of Kwanganok, Kwangpyeongok, Cheonganok, Cheongsaok, and Suwon159 was not different from that of P3394. Duruok, Kwangpyeongok, and Suwon159 were more resistant to Bipolaris maydis (southern corn leaf blight) than P3394. All of the silage corn hybrids were resistant to Exserohilum turcicum (northern corn leaf blight) and Smut. Ear ratios to total dry matter (%) of Cheonganok was similar to P3394. Ear lengths of domestic hybrids were similar or longer than that of P3394. Dry matter yield of domestic hybrids except Suwon19 and Jangdaok were similar to that of P3394. Total digestible nutrient (TDN) yields, Duruok, Kwangpyeongok, Cheonganok, and Cheongsaok were similar to P3394, but Kwanganok, Suwon19, Jangdaok and Suwon159 were lower than P3394. Acid detergent fiber(ADF), Suwon19 was lowest among all hybrids, and all hybrids except Suwon19 had values ranging from 44.7 to 49.0%, similarly with P3394. Neutral detergent fiber (NDF) values of the hybrids were similar to that of P3394, and ranged from 68.1 to 72.8%, except for Duruok which was lowest. Relative feed values (RFV) of Duruok, Kwangpyeongok, Cheonganok, Jangdaok, and Suwon159 had values ranging from 71.0 to 75.7 and were not significantly different from P3394. ADF was significantly negatively correlated with number of days to silking, number of days to maturity, and fresh matter yield, but was significantly positively correlated with resistance to corn borer. RFV showed a significantly positive correlations with no. of days to maturity and fresh matter yield, but significantly negative correlation with resistance to European corn borer. Therefore, indices for evaluation of feed value as well as production were important to select corn hybrids for silage. It is concluded that domestic hybrids tested in this study have high feed value as well as high production similar to those of imported corn hybrid.

차선우,문현귀,정태욱,손범영,박남규,김성국,류용환 한국육종학회 2004 한국육종학회지 Vol.36 No.1

Sinchalok, a new waxy corn hybrid was developed from the cross between two inbred lines KW36 as a seed parent and KW1 as a pollen parent at the National Crop Experiment Station, RDA in 2001. Sinchalok was 66 days in days to silking and early maturity hybrid to be similar to Chalok1. Sinchalok is a short-stature hybrid, of which plant height was 185cm. Sinchalok was similar to Chalok1 as 16.8cm in ear length, but larger in ear diameter. Sinchalok was relatively resistant to Biporalis maydis (Southern leaf blight) and maize dwarf mosaic virus. Lodging resistance of Sinchalok was intermediate, but more resistant than that of Chalok1. Sinchalok was compared with Chalok1 as the designation of Suwon32 at four sites for three years from 1999 to 2001. In these tests, the fresh ear weight of Sinchalok was 10.36 ton/ha and 19% higher than that of Chalok1. Sinchalok is adaptable to all over the country including early-planting culture region of the southern part of Korea.

A single cross, Jangdaok, is an yellow dent maize hybrid (Zea mays L.) developed by the maize breeding team at the National Institute of Crop Science (NICS), RDA in 2003. This hybrid, which has a high yield of dry matter, total digestible nutrients (TDN) and grain, was produced by crossing two inbred lines, KS5 and KS135. KS5 is the seed parent, and KS135 is the pollen parent of Jangdaok. Silking date of Jangdaok is three days earlier than that of check hybrid, Kwanganok. It is resistant to lodging because of its low ratio of upper ear height to plant height. Stay-green of Jangdaok do not differ greatly with that of Suwon19. It has a longer ear than a check hybrid, Kwanganok. It is moderately resistant to Bipolaris maydis (southern corn leaf blight), Exserohilum turcicum (northern corn leaf blight), and corn borer but sensitive to black streaked dwarf virus (BSDV). Regional yield trial was conducted at four locations for two years. The yields of Jangdaok in dry matter, TDN, and grain were 17.7ton, 12.7ton and 9.2ton/ha, respectively, which were increased 6% and 8% compared with a check hybrid, Kwanganok, and 9%, compared with Suwon19. Seed production of Jangdaok has gone well due to a good match during crossing between the seed parent, KS5 and the pollen parent, KS135.

옥수수의 품질평가 현황과 전망

김선림,문현귀,유용환 韓國作物學會 2002 한국작물학회지 Vol.47 No.S

This paper is intented to present a information of various aspects of quality related characteristics and standards for grades in maize. Maize is world's one of the three most popular cereal crops and a primary energy supplement and can contribute up to 30, 60, and 98% of the dairy diet's protein, net energy, and starch, respectively. Maize is also processed into industrial goods by wet or dry milling. Sweet corn is a leader among vegetable crops and its production for fresh or processing markets is a major industry in many countries. Over the years, the combined efforts of breeders and geneticists, biochemists, food scientists, and others have helped bring us to the point where we understand issues related to sweet corn quality. Traditional criteria for selecting corn hybrids have been based primarily on agronomic factors, including grain production, disease resistance, drought tolerance, and storage characteristics. Little emphasis has been placed on the quality and nutritional values of corn. Although there is widespread interest for value-enhanced corns have increased tremendously in the last five years, there is limited information available on the production and comparing the quality attributes of specialty grains with those of normal yellow dent corn. Most countries have developed national maize standards, aiming to provide a framework for trade, both internal and external. Where trading involves direct choice and price negotiation in front of the commodity, grading standards are rarely employed; quality is assessed visually and is influenced by end-use, and the price is determined more by local rather than national factors. The use of an agreed standard will provide an unambiguous description of the quality of the consignment and assist in the formation of a legally-binding contract. Standards can also be seen to protect consumers rights through setting limits to the amount of unsuitable or noxious material.
