摘要

本試驗採用從臺灣9個縣巿採集的23個採集代號的鐵炮型百合種子，每個採集代號使用300－800粒種子不等，進行種子低溫層積、穴盤育苗後，定植於埔里分場田間栽植，調查百合實生苗之存活率、抽莖率及開花率，並篩選出生育強健及早熟開花的個體54株。於秋季休眠期挖掘54株選拔株的鱗莖，其中11株獲得鱗莖進行鱗片繁殖，鱗片球在一個生長季栽培後採收鱗莖，進行第二次鱗片袋裝繁殖，以篩選鱗片繁殖倍率高及鱗莖發育存活率高之單株。試驗結果顯示，採自苗栗後龍的L399S-4、新北南雅的L408S-1及L408S-5等三株，養球期間種球存活率較高可達80.6%以上，單球比例分別為87.2%、77.1%及62.8%，為本次試驗經歷早熟開花、鱗莖生育及鱗片繁殖倍率等三階段篩選出3個較佳的原生鐵炮型百合單株，後續將進行品系試驗及區域試驗，以培育新的鐵炮型百合品種。

The longiflorum-type lily seeds of 23 collection number were collected from 9 counties and cities in Taiwan and used in the experiment. Three hundred to 800 seeds per collection number were used for this experiment. After stratification, sowning and plug propagation, seedlings were transplant to field in Puli Branch, TDARES. Survival rate of nursery, emergence percentage and flowering ratio were investigated. Fifty-four seedlings with strong growth vigor and early maturity were selected. Eleven bulbs for scald propagation were dig from 54 selected plants after dormancy in fall. Bulblets from scale were cultured and harvested after one growth season for second times scale propagation to select plants with high scale propagation rate and survival rate. In this experiment, three individual plants of longiflorum-type lily were selected via three section, including the screening of early maturity, bulb growth and scale propagation rate. These 3 plants will continue to undergo strain test and regional test to develop new longiflorum-type lily varieties.
