Plenty of variations in nutritional, morphological and agronomic traits occur in the pigmented rice germplasm. The current study was conducted to evaluate the growth characteristics of 71 pigmented rice genotypes having different origin taking one Korean landrace (Heugjinjubyeo) as control. Amongst the twenty eight growth characters studied; leaf length, leaf width, ligule length, panicle length and panicles per hill showed a higher degree of variance. The heading dates of the pigmented rice germ plasm were distributed from Aug. 1 to Sep. 28. Thirty five cultivars that headed or flowered in August were found adaptable for cultivation in Korea. The mean culm length and panicle length were significantly higher than Heugjinjubyeo but most of cultivars having strong or middle of culm strength made it possible to produce the stable yield. Some cultivars showed unique qualitative characters such as openness of culm angle, purple ligule, auricle, awn and glume colors, poor panicle exsertion and long empty glume. Nine cultivars including Heugjinjubyeo showed purple seed coat color while those of the others (62 cultivars) were of red seed coat.

본 시험은 제주지역에서 점파립수(1, 2, 3, 4, 5 및 6립)에 따른 제주재래수수의 생육반응, 수량, 사료가치를 구명하기 위하여 2000년 4월 3일부터 9월 6일까지 수행한 결과를 요약하면 다음과 같다. 출수기까지의 일수는 66일에서 69일로 점파립수 간에 큰 차이가 없었으나, 점파립수가 많을수록 출수기까지의 일수는 지연되는 경향이었다. 초장은 1립 점파에서 201.6cm이었던 것이 3립에서 206.7cm로 길어졌으나, 점파립수가 그 이상으로 증

Background : The study is investigated the development of high-quality standard variety, character of gene resources, growth and yield production to collecting varieties in Agastache rugosa O. Kuntze containing antioxidant agriculturally. Methods and Results : Character of gene resources investigated collecting 16 varieties (Jeonnam Naju 1, 2, 3 (NJ), Gwangyang 1, 2 (GY), Sooncheon 4 (SC), Boseong 1, 2 (BS), Yeosu (YS), Jangheung (JH), Jindo (JD), Gyeongnam Hamyang (HY), Gyeongbuk Bonghwa (BH), Chungbuk Eumseong (ES), Cheongju (CJ), Gangwon Cheolwon (CW). Method of cultivation were conducted under sowing dates of plant a seedling were April 24. Transplanting with Agastache rugosa O.K. seeds in June 27 by growing pot seedling for 60 days in 2017. Fertilization application were standard application (N-P-K-Compost applied at 12-16-10-600 ㎏․10a−1). N-K applied at 60% of basal fertilizer, 40% of top dressing were two times (N-K) application. Planting density were spaced 30 ㎝ apart in rows 20 ㎝ apart with with non-woven fabric mulching cultivation. Plot design randomized block 3 repetition. Conclusion : Endemic characteristics of gene resources to collecting variety in leaf color (light green), leaf pliable (softness) appeared 8 lineage, leaf color (deep green), the contrary leaf pliable (roughness) showed 8 lineage. Flower color bloomed in light purple 8 lineage flower deep purple color come into 8 lineage. Also, the period of maturity ripened Sept. 27 - 31. on 8 lineage (BS2, GY1, JD, HY etc.). 3 lineage (YS, CJ, CW) attained to maturity on Oct. 14 - 16. Growth of aerial part increased on long length, large width of leaf, heavy dried weight of leaf and weight of seeds 10 lineage SC4, GY1, 2, NJ2, 3, BS1, 2, CJ, ES, BH etc. but short length, small width of leaf, declined in light dried weight of leaf and weight of seeds 2 lineage YS, CW.

Italian Ryegrass is a high productivity and feed value, and an upright grass that behaves like a biennial or short-lived perennial. It grows vigorously in winter and early spring. Italian ryegrass and a related species, perennial ryegrass, Lolium perenne, are the two common weedy ryegrassses. Italian ryegrass and perennial ryegrass can hybridize, resulting in offspring that are difficult to identify as either species. Ryegrasses are cultivated for turf and forage. Sometimes Italian ryegrass is grown as cover crop. It has the potential to produce high yields and, with proper management, can be high quality with good animal performance. To develop of a high quality, productivity and early variety, 20 varieties examined growth and yield characteristics. The heading date of Green farm with high cold tolerance was on 28 April. Most of Introduced varieties except Grazer have mid and late heading date.
