신광옥은 다수성 사료용 옥수수 품종 개발을 목표로 2012년에 농촌진흥청 국립식량과학원에서 자식계통 KS172과 KS173을 교잡하여 육성한 다수성 단교잡종이다. 신광옥의 종피색은 황오렌지색이며 입질은 중간종이다. 신광옥은 2008~2009년 동안 생산력검정시험을 거쳐 2010~2012년까지 3지역에서 지역적응시험을 실시하였다. 그 결과 우수성이 인정되어 2012 농작물 직무육성 신품종으로 결정되었고 신광옥으로 명명하였다. 신광옥의 출사일수는 대비품종인 장다옥과 비슷하다. 간장은 장다옥과 비슷하나 착수고율은 장다옥보다 낮고 도복은 장다옥과 비슷한 정도로 강하다. 100주당 이삭은 장다옥보다 17개 더 많고 이삭길이는 장다옥과 비슷하며, 100립중은 장다옥과 비슷하다. 깨씨무늬병 저항성은 중강이며, 그을음무늬병에는 강한 편이다. 검은줄오갈병, 이삭썩음병 및 조명나방 저항성은 중 정도이다. 신광옥의 종실수량은 7.8톤/ha로 장다옥과 비슷하다. 4:1(모본:부본) 재식비율로 동시 파종하여 채종 시험한 결과 종자친(모본) 출사기와 화분친(부본) 화분비산기간이 일치하였으며 채종수량은 3.84톤/ha이었다. 신광옥은 전국적으로 재배가 가능하다.

평강옥은 자식계통 KS160과 KS155의 교잡으로 육성된 다수성인 단교잡종이다. 2007~2008년 생산력검정시험을 거쳐, 2009~2011년 3년 동안 4지역에서 지역적응시험을 실시한 결과 그 우수성이 인정되어 2011 농작물 직무육성 신품종선정위원회에서 신규 우량품종으로결정되었다. 이 품종의 주요특성을 요약하면다음과 같다. 평강옥의 종피색은 황색이며 입질은 마치종이다. 출사일수는 종실용 옥수수대비품종인 장다옥 보다 2일 빠르며 사일리지용 옥수수 대비품종인 광평옥과 같다. 간장은장다옥 보다 길며 광평옥과 비슷하였다. 100주당 이삭수는 장다옥 보다 많았다. 이삭길이는장다옥과 비슷하였으며, 100립 중은 장다옥 보다 가벼웠다. 이삭비율은 광평옥 보다 낮았다.후기녹체성은 광평옥과 비슷하였다. 깨씨무늬병, 흑조위축병 및 조명나방에 중정도의 저항성을 보이며, 그을음무늬병에는 강한 편이다.도복에는 광평옥과 비슷한 정도로 강하였다.종실수량은 7.66톤/ha로 장다옥 보다 많았고,건물수량은 19.80톤/ha로 광평옥과 비슷하였다.TDN 수량은 13.32톤/ha로 광평옥과 비슷하였다. 4 1 (모본 : 부본) 재식비율에서 동시 파종하여 채종한 결과 모본의 출사기와 부본의화분비산기간이 잘 일치하였다.

본 시험은 친환경농업 및 조사료 용도로 재배가 증가하고 있는 헤어리베치를 대상으로 국내 헤어리베치 종자 채종 시 개화 후 경과 일시에 따른 채종 수량 추이를 조사하여 안전 다수확 채종 기간을 구명하기 위하여 경기도 수원시에 위치한 농촌진흥청 국립식량과학원 시험포장에서 헤어리베치 품종 ‘청풍보라’를 이용하여 2009년부터 2011년까지 3개년에 걸쳐시험하였다. 2009년도는 개화 후 35일 (6월 11일), 42일 (6월 18일), 48일 (6월 24일), 54일 (6월 30일), 58일 (7월 4일) 등 5회, 2010년도는개화 후 35일 (6월 21일), 42일 (6월 28일), 48일(7월 4일), 54일 (7월 10일), 58일 (7월 14일) 등5회, 그리고 2011년에는 개화 후 39일 (6월 21일), 49일 (7월 1일), 53일 (7월 5일) 등 3회 수확하여 종자 수량과 발아율을 조사한 결과 종자 수량은 개화 후 경과 일수와 비례하여 증가하다가 개화 후 42일 (2010년도), 49일 (2011년도), 54일 (2009년도)에 정점을 나타낸 이후 도복으로 인한 꼬투리 소실로 수량이 감소하였다. 수확 시기가 늦어질수록 1,000립 중과 발아율이 증가하였으나 장마기 이후에 수확 된 종자는 수발아 종자 발생이 증가하였다. 이상의본 시험 결과에 의하면 헤어리베치 종자 안전다수확을 위한 수확 시기는 개화 후 42일에서54일 사이에 장마 전 기간으로 판단되었다.

A chemical, MNU-induced hulless barley mutant line designated as 'Mutant 98 (M98)' was developed from a Korean hulless waxy barley cultivar, 'Chalssalbori'. The objective of the study was to determine the genetic basis of 'M98' and the possibility of using 'M98' as breeding parent to improve lysine level. Compared to 'Chalssalbori', 'M98' had large embryo and higher lysine content in both the embryo and endosperm. Significantly different lysine content in 'M98' and the other high-lysine barley mutant stocks was observed for two years. However, the genotype by year interaction was not significant. 'M98' was higher than the other high-lysine barley mutant stocks in the percentage of lysine of total amino acid composition (0.75%). The trait of shrunken endosperm of 'M98', which was typical in the high-lysine mutants, was inherited by a single recessive gene. Based on seed morphology and lysine content of F1 seeds, 'M98' had a genetically different gene from the other high-lysine mutants for shrunken endosperm. Segregation of F2 for plump/shrunken endosperm did not fit the expected ratio of Mendelian inheritance except for only one cross combination (GSHO1784 (lys1)/M98). The amino acid analysis of F5 and F6 progenies from the cross between 'M98' and 'Chalssalbori' revealed that the attempt to increase the range of lysine content of plump lines did not go beyond the limit of the average high-lysine barley germplasm.

“Hwanggeumchal”, a new covered waxy cultivar derived from the cross between “Chalssalbori” and “Milyang 65” with waxy endosperm and early maturing cultivars, respectively was developed at Honam Agricultural Research Institute (HARI), NICS, RDA, 2006. The origin of “Hwanggeumchal” is “Suwon 403” (SB942090-B-B-B-42-1). The initial cross was made in 1994 and the selected line showed a high yield and good quality characteristics under yield trial test in 2003. “Suwon 403” consistently performed well for three years (2004-2006) from the four locations of regional yield trial (RYT) in Korea and released as “Hwanggeumchal”. The characteristics of “Hwanggeumchal” were the following: rate I growth habit, green leaf and stem, compact spike and with long rough awns. The heading date was April 30 in upland and April 28 in paddy field, which was 1 and 4 days later than that with check cultivar, “Seodunchalbori”. The culm length was 81 cm which was 3 cm shorter than those with check cultivar. It showed spike length of 4.5 cm and 633 spikes per m2, 64 grains per spike, 27.6 g of 1,000-grain weight and 632 g of test weight. It showed stronger winter hardiness and higher resistance to barley yellow mosaic virus (BaYMV) than those with check cultivar. It had yellow aleurone and showed higher water absorption, expansion rate and total phenol content than those of check cultivar, but lower protein, β-glucan content and pearling rate. The average yield of the pearled grain in the RYT was 4.04 ton ha-1 in upland and 4.12 ton ha-1 in paddy field, which was 10% higher and 4% lower than that of the check cultivar, respectively. This cultivar would be suitable for the area above the daily minimum mean temperature of -8℃ in January in Korean peninsula.

“Hyemi”, a new covered cultivar derived from the crosses between “Suwon 298” and “Milyang 34/Albori//Dongbori” developed at the Honam Agricultural Research Institute (HARI), NICS, RDA in 2006.

The initial cross was made in 1995 and the selected line showed a high yield and good quality characteristics under yield trial test in 2003. “Suwon 400” consistently performed well for three years (2004-2006) from the four locations of regional yield trial (RYT) in Korea and released as “Hyemi”. The characteristics of “Hyemi” were the following: rate Ⅳ growth habit, green leaf and stem, compact spike and with long rough awns. The heading date was April 29 in upland and April 23 in paddy field, which was similar and 2 days earlier than that with check cultivar, “Olbori”. The culm length was 81 cm which was 4 cm shorter than those with check cultivar. It showed spike length of 4.1 cm and 646 spikes per m2, 52 grains per spike, 33.4 g of 1,000-grain weight and 672 g of test weight. It showed similar winter hardiness and higher resistance to barley yellow mosaic virus (BaYMV) than those with check cultivar. It showed higher protein content, whiteness and total phenol content than those of the check cultivar, but lower β-glucan content and pearling rate. The average yield of the pearled grain in the RYT was 3.95 ton ha-1 in upland and 4.38 ton ha-1 in paddy field, which was 13% and 16% higher than that of the check cultivar, respectively. This cultivar would be suitable for the area above the daily minimum mean temperature of -8℃ in January in Korean peninsula.

‘Zasoojeongchal’ is a new colored naked barley cultivar developed from the cross between HB83072〔Tapgolbori / HB 78100-B-17-3-2〕, a disease resistant and good quality line and ‘Dokusima mochi hadaka’, colored naked cultivar with waxy endosperm by the Honam Agricultural Research Institute (HARI), NICS, RDA in 2006. An elite line CNB7-13-37-2-5-3, was selected in 2002 and designated as ‘Iksan 81’. It showed good agronomic performance in the regional yield trials (RYT) from 2005 to 2006 and was released with the name of ‘Zasoojeongchal’ possessing purple colored waxy endosperm. The average heading and maturing dates of ‘Zasoojeongchal’ were May 2 and Jun. 7, which were two and five days later than those of the check cultivar ‘Saechalssalbori’ respectively. The new cultivar, ‘Zasoojeongchal’, had 75cm of culm length that was 4cm shorter than that of ‘Saechalssalbori’, and 5.4 cm of spike length. It showed 607 spikes per m2, 63 grains per spike, 27.2 g of 1,000-grain weight, and 771 g of test weight. ‘Zasoojeongchal’ showed weaker winter hardiness, but better resistance to powdery mildew and BaYMV (Barley yellow mosaic virus) than those of the check cultivar, ‘Saechalssalbori’. It showed higher ß-glucan content, anthocyanin content, water absorption rate and expansion rate than those of the check cultivar, ‘Saechalssalbori’. Its average yield of the pearled grain in the regional yield trial was 2.67 MT/ha in upland, and 3.49 MT/ha in paddy field, which were 26% and 6% lower than those of the check cultivar, respectively. This cultivar would be suitable for the area above the daily minimum temperature of -6℃ in January in Korean peninsula.
