        This study was carried out to develop rice growth model when cultivate early maturing rice cultivar, Unkwangbyeo, in Honam plain area. To confirm leaf emergence rate and variation of heading date, we transplanted 15 day and 30 day old seedling on May 1, May 15, May 31, June 15, June 30, respectively. The growth duration between transplanting and completion of leaf emergence on main culm were 50.1~78.3 days in 2007 and 47.5~74.7 days in 2008. Growth duration diminished gradually as transplanting time delayed, but the difference of growth duration by transplanting time were more bigger than that of seedling day. The emerged leaf number after transplanting on main culm were 8.9~10.9 in 2007 and 8.4~10.9, respectively. The emerged leaf number diminished as transplanting time delayed, but the difference of emerged leaf number by transplanting time were more bigger than that of seedling day. The cumulative temperature between transplanting and completion of leaf emergence on main culm were 1,281~1,650℃ in 2007 and 1216~1560℃ in 2008. The solar radiation between transplanting time and completion of leaf emergence on main culm were 709~1,245MJ/㎡ in 2007 and 722~1,220 MJ/㎡ in 2008. The sunshine hours between transplanting time and completion of leaf emergence on main culm 234~433 hours and 238~431 hours, respectively.

        영남평야지 조기재배시 국내 육성된 고품질 조생종 품종들의 품질에 미치는 영향을 살펴본 결과를 요약하면 아래와 같다. 1. 공시품종들의 평균 출수기는 7월 22일로 8월 하순에서 9월 상순사이에 수확이 가능한 것으로 판단되었고, 공시품종들의 평균 수당립수, 등숙율 및 수량에서 품종간 유의한 차이가 있었으며, 운광벼가 수량이 529 kg/10a로 가장 많았다. 2. 수확시기별 현미 품위를 조사한 결과 동할미 발생을 줄이고 현미 정립율을 높이기 위해서는 출수 후 40일경에 수확하는 것이 정립은 8월25일~ 9월1일 사이 수확하는 것이 가장 높았으며, 수확시기가 늦어질수록 미숙립의 발생은 감소하고 동할립의 발생은 증가하였다. 백미 완전미는 중화벼와 고운벼가 72.2%와 71.0%로 높았으나 싸라기 발생이 높았으며, 운광벼와 오대벼는 분상질의 발생이 많았다. 3. 운광벼와 오대벼는 백미 단백질 함량은 6.4%로 낮았으며, 식미관능검정의 총평이 각0.6 및 0.5로 밥맛이 양호하였다.

        A new early maturing satsuma mandarin (Citrus unshiu Marc.) ‘'Haryejosaeng’' was developed as a nucellar seedling selection of ‘'Tachima Wase’' (C. unshiu Marc.) that was crossed with C. natsudaidai Hayata at the National Institute of Subtropical Agriculture in Jeju island in 1992. The ‘'Jegam ga No. 2’', a first selection from the seedlings fruited in 2001 was finally named “"Haryejosaeng”" through field evaluation trials at three locations in Jeju island from 2003 to 2004. ‘'Haryejosaeng’' produces seedless fruit maturing in early November, and has higher soluble solids and lower acidity than ‘'Miyagawa Wase’', the leading early-maturing satsuma mandarin cultivar in Jeju island. Fruit weight is moderate at about 80~90 g and its shape is compressed-oblate globose with a light orange color. The rind thickness of about 2 mm provides easy peeling. The flesh shows light orange colored and contains 10 to 11 Brix and 1 to 1.1% acidity when mature. Tree shows vigorous growth and spreading thornless twigs. Alternate bearing is similar to ‘iyagawa Wase’ ‘aryejosaeng’is susceptible to citrus scab disease and melanose, but resistant to citrus canker.

        A new peanut variety “eonan”(Arachis hypogaea ssp. hypogaea L.) was developed at the Yeongnam Agricultural Research Institute, NICS, in Milyang in 2007. It was developed from the cross between the erect short stem cultivar “P9128” and the high-yielding cultivar “aekwang” “eanan”which is Virginia plant type has 18 branch number per plant with early maturing and long-ellipse shaped large kernel. Each pod has two grains with brown testa and 100 seed weight was 87 g in the regional yield trials (RYT). Especially this variety has resistance to lodging owing to short stem. The free sugar and tannin content of fresh peanut are 3.7% and 0.48%, respectively, similar to check variety. In the regional yield trials “eonan”was outyielded than check variety by 14% with 8.59 MT/ha for fresh pod and by 7% with 3.75 MT/ha for grain.

        본 연구는 주요 조생종 콩의 생육과 종실품질 및 수량을 비교하여 남부지방 다모작 재배농가의 조생종 콩 품종선택에 활용하고자 전남 나주(위도 35˚04'N, 경도 126˚54'E)에서 6월 15일에 파종하여 수행하였다. 큰올콩과 화성풋콩은 성숙기가 9월 12일로 빨라 작부체계 도입에 유리할 뿐만 아니라 종실품질과 수량이 양호하였다. 그리고 새올콩과 신록콩은 성숙기가 9월 20일 전.후로 조금 늦으나 종실품질이 좋고 수량이 많았다. 따라서 콩 후작물을 9월 중순에 파종하고자 할 때는 큰올콩과 화성풋콩이, 9월 하순에 파종하고자 할 때는 새올콩과 신록콩이 유리하였다. 그리고 주요 조생종 콩의 조기수확에 따른 종실품질과 수량성 등을 검토하여 조기수확 한계기를 구명하고자 수행하였다. 큰올콩은 수확적기(9월 12일)보다 6일전(9월 6일)에 수확할 때 입중, 수량, 종실품질 등이 적기수확과 차이가 없었다. 한편 새올콩은 수확적기(9월 24일)보다 6일전(9월 18일)에 수확할 때 입중, 수량, 종실품질 등이 적기수확과 차이가 없다. 따라서 큰올콩과 새올콩의 안정적인 조기수확 한계기는 수확적기 6일 전이다.

        "Gounbyeo" is an early-maturing and good quality japonica rice variety that was developed by the rice breeding team of National Institute of Crop Science, RDA, in 2004. "Gounbyeo" was derived from a cross between Jinbul0 and Jinbul7. This variety has early heading date of July 28 and medium culm length of 68 cm, similar to Odaebyeo. It is moderately resistant to blast disease, but susceptible to bacterial leaf blight, virus diseases and insect pests. Gounbyeo showed less delay of heading date and higher grain fertility than Odaebyeo in cold-water irrigated nursery, Chucheon. The milled rice of Gounbyeo exhibits translucent, clear non-glutinous endosperm and medium short grain. Gounbyeo has lower amylose content of 18.5% and similar gelatinization temperature and good palatability of cooked rice compared to Odaebyeo. The average milled rice yield of this variety is 5.29 MT/ha at ordinary cultivation in local adaptability test for three years. Gounbyeo would be highly adaptable to mid-northern mountainous area and eastern coastal areas of Korea.

        "Oraebyeo" is mutation of a high quality japonica cultivar, Ilpumbyeoa new japonica rice(Oriza sativa L.) cultivar developed from by N-methyl-N-nitrosourea(MNU) treatment on fertilized egg cell by the rice breeding team of Gangwon Provincial Agricultural Res. & Ext. Service in 2006. This variety heads 20 days earlier than Ilpumbyeo and similar to that of Odaebyeo an early maturing leading cultivar of northern plain area of Korea. Compared with Odaebyeo has a good semi-erect plant type with lodging tolerance due to much shortened plant hight(l2cm shorter than Odaebyeo). Oraebyeo has similar panicle number with Odaebye where as it has more spikelets per panicle. However, this variety less the ratio of ripened grains and 1,000 grain weight than those of Odaebyeo. The yield performance of this cultivar in milled rice was about 5.09MT/ha in local adaptability test conducted for three years 2002-2004 and 5.51MT/ha in the demonstration plot of farmer's field.

        A ruminant-palatable barley cultivar, Soman (Hordeum vulgare L.), with early maturing, high silage quality and high yield, was developed from the cross between SB79124〔Bengei-Ginomeo-Buheung-Morsen-Hagane/Gangbori〕and SB77189 〔Samjug/Riso82//Olbori〕in 1994. A promising line “SB941067-B-B-B-45” was selected in 1998. It performed well in the preliminary and advanced yield trials for two years from 2002 to 2003. The line was designated ‘Suwon 404’ through the regional yield trials (RYT) at six sites for three years from 2004 to 2006. Its growth habit was winter type (Ⅲ) with greenish leaves, medium culm and compact density of spike setting. Its heading date and early dough stage were Apr. 23 and May 26 respectively, which were 6 days earlier than those of check cultivar ‘Olbori’. ‘Soman’ showed weaker winter hardiness, but better resistance to lodging, shattering, and BaYMV (Barley yellow mosaic virus) than those of check cultivar ‘Sunwoo’. It showed 1.7% higher TDN content on whole-crop-silage than that of check cultivar ‘Sunwoo’. Its average of forage yield in regional yield trials was 10.31 MT/ha, which was 4% higher than that of the check cultivar.
