摘要

仙草(Mesona procumbens Hemsl.)農試1號，原品系代號78-T-1，於1989年自苗栗縣銅鑼地區之混合族群中選出，歷經品系觀察試驗、品系比較試驗、區域試驗、肥料試驗、各種栽培技術改進試驗與品質分析等，確定其各項農藝特性及品質優異，經審查通過而命名。本品種植株屬匍匐型，莖淺紫紅色、絨毛短疏，葉大呈橢圓形，葉脈紋深、葉面光滑，葉長5.2 cm、葉寬2.7 cm，葉色鮮綠、葉緣淺齒狀，節間短，僅見葉不見莖，營養生長期約為180天左右。農試1號於區域試驗之表現，每公頃平均產量最高達10,000 kg，葉產量達3,000 kg左右，葉凝膠強度高，於剛收穫時測定1 Brix達30.2 g/平方公分，多醣膠體含量17.7 %，清除超氧陰離子效果可達91.5 %，適合於中南部及新竹地區栽培。

A new hsian-tsao (Mesona procumbens Hemsl.) variety 'TARI No. 1' was selected from Tunglo at MiaoLi county by Taiwan Agricultural Research Institute of the Council of Agriculture. A clonal selection method was used to select from a population of 3,600 since 1989. A new clone was selected by its better agronomic characteristic performances through varietal observation test, comparative test, regional test and quality analysis. Variety of 'TARI No. 1' was released to growers in September 1999 as a registered new cultivar with many outstanding characteristics. Variety of 'TARI No. 1' belongs to a runner and leafy growing type. The cane color is pale purple with short and sparse pubescences on it. It has a pale green ellipsoidal leaf shape with medium dentation on margins and leaf size is about 5.2 cm in length and 2.7 cm in width. A growing duration of 180 days from transplanting to the appearance of flower buds, is needed for vegetative growing according to the results of varietal observation. The highest yields of whole plants or from leaf only are up to 10,000 kg/ha and 30,00 kg/ha according to the regional test, respectively. A strong gel formation strength of 30.2 g/cm^2 and a high scavenging activity on superoxide anions and of poly-saccharide polymer content in leaf extraction, 91.5% and a 17.7%, respectively, are obtained from fresh harvested plants of 'TARI No.1'. Variety of 'TARI No. 1' is adapted to the middle and southern part of Taiwan and in the Hsin-Chu area.
