        본 시험은 동계작물인 쌀보리의 알곡에 대한 사료로서의 활용도를 제고하고자 미생물 분포를 분석하고, 발효과정 중 이화학적 및 미생물학적 특성의 변화 분석을 통하여 효 과적인 발효사료 제조방법을 제시하고자 수행하였다. 즉, 수확된 쌀보리 종실에 시판 생균제를 기준에 맞게 접종한 후 공기와 접촉하지 않도록 밀봉하여 37℃에서 7일간 발 효를 통해 쌀보리 종실의 저장성과 안전성을 증진시킬 수 있다. 쌀보리 종실 자체에 Staphylococcus속과 Bacillus속의 미 생물들이 다수 존재하여 자연발효의 가능성이 있음을 보여 주었다. 또한 생균제를 접종하지 않은 쌀보리 종실도 기간 이 경과됨에 따라 산도가 저하되고 유산균 수가 증가하여 발효가 이루어지고 있는 것으로 나타났다. 그러나 쌀보리 종실에 생균제를 접종하였을 경우, 발효 7일차에 pH가 4.33±0.02로 발효가 더 빨리 진행되었으며, 유산균의 수도 전체 발효기간 동안 미 접종 대조구에 비해 높게 유지되었 으나, 효모의 수에 있어서는 차이가 나타나지 않았다. 발효 에 의해 쌀보리 종실의 산도가 저하됨에 따라 초기 107 cfu/g 이상 검출되었던 대장균이 발효 7일차 이후부터는 전 혀 검출되지 않아 발효가 쌀보리 종실의 안전성을 유지시 키는 데 있어 효과적인 저장방법으로 나타났다.

        본 연구는 우수한 흑쌀보리 육성을 위하여 동아대학교 종합농장 수도포장에서 실시하였다. 시험에 사용된 교배친은 무조성인 흑피맥 Otello, 늘쌀보리 및 흰쌀보리 등 3품종으로 2000년 4월에 교배하여 6월에 채종하였다. 그리고 2001년 F1세대를 거쳐 2002년 F2세대에서 2007년 F7세대까지 12계통을 분리계대육성하여 homo화 시켜 흑쌀보리의 육성의 교배친과 이들 F7세대의 교배조합에 대한 유전력과 상관관계에 대한 연구 결과는 다음과 같다.교배친에서는 유전분산이 환경분산에 비하여 높았으며 유전분산은 천립중이 15.2658로 가장 높았던 반면, 망장이 0.0833으로 가장 낮았고 모든 형질에서 고도의 유의성을 나타내었다. 유전력은 β-glucan이 99.99%로 가장 높았으며 망장을 제외한 각 조사형질에서 95%이상의 높은 수치를 보였다. F7세대의 교배조합에서도 모든 형질에서 고도의 유의성을 나타내었으며, 유전분산에서 천립중이 6.9148로 가장 높았다. 교배친에서 β-glucan 함량과 천립중간에, β-glucan 함량과 망장간에서는 유의한 정의 상관이었고, 수장과 β-glucan 함량간에는 부의 상관을 보였다. F7 세대의 교배조합에서는 천립중과 β-glucan 함량간에서 정의 상관을 보였으나 그 수치는 다소 낮았다.

        The limited use of barley for food is mostly due to undesirable color and unfamiliar flavor of barley based food products. So, preventing the browning is very important in order to increase the consumption of barley. ‘Yeongbaekchal’is a new naked waxy barley cultivar which is not get discolored. It was developed by the National Institute of Crop Science, RDA in 2013. It was derived from the cross between‘Radiant’which is a proanthocyanidin free and ‘Saechalssal’ which has characteristics of winter hardness, lodging tolerance, waxy endosperm and good cooking. The initial cross was done in 2006 and the selected line, ‘Iksan116’(HB16953-B-B-7), had no proanthocyanidin and showed good quality characteristics under yield trial test from 2012 to 2013. Heading and maturing date of ‘Yeongbaekchal’ were 3days late than those of ‘Saechalssal’. It had 90 cm of culm length and 5.0 cm of spike length. It showed 840 spikes per m2, 63 grains per spike, 25.1 g of 1,000-grain weight, and 831 g of test weight. ‘Yeongbaekchal' showed better resistance to BaYMV (Barley yellow mosaic virus) and similar water absorption rate and expansion rate with the check cultivar. Its average yield of the pearled grain in the regional yield trial was 3.42 MT/ha in paddy field, which were 5% lower than that of the check cultivar. It showed a little discoloration during the storage after cooked.

        In general, since partial pollen is derived to sporophyte, anther culture efficiency is low, and practical application that is introduced in actuality breeding technology is not many. This study was carried out to improve regeneration of green plants through some culture environments contol in anther culture of naked brley. Among the factors related with plant regeneration, medium was effective in component containing L-glutamine 256 mg/L, L-proline 250 mg/L, IAA 1 mg/L and BAP 2 mg/L controlled in addition sucrose 30 g/L or maltose and sucrose mixed each 30 g/L to increase both plant regeneration and green plant regeneration rate. Also, adequate content of CuSO4 was the best at 1.25 mg/L (fifty-fold), it was tendency to decrease albino production rate. Starvation was effective at 30℃, 7 days in case of Saessalbori for plant regeneration and Dooweonchapssalbori at 30℃, 10 days with increasing green plant regeneration against albino. After plant regeneration, under acclimation by hydroponics, roots and shoots were well developed at 20℃, light control as 2,000~5,000 Lux and photoperiodic reaction by 14/10 as dark/light in the early growth stage. In acclimation method, plants acclimated in the modified Yoshida solution filled-vermiculite in GP pot is superior (100%), in which was controlled by temperature 20℃, pH 6.0 and relative humid 90% over, especially, after transplanting in pot growth of root, sheath and leaf are more active in 20℃ and 5,000 Lux control. For Vernalization, plants derived from anther culture of F1 naked barley was different from their parents with normal heading plant even about 50% in the F1 hybrids whose vernalization was strong, whereas the rest of plants derived from anther culture formed rosette, showing that normal growth were impossible.
