Abstract
臺灣藜目前在臺灣各地栽培的地方品系均為高異質性族群，植株性狀極不整齊，不易進行經濟栽培。本研究建置臺灣藜種原庫、繁殖目前蒐集地方品系之種子，並於田間進行性狀調查。目前已於台東、花蓮及屏東等地蒐集了20 個地方品系。經觀察，初步依據穗色多型性族群另編色號1~3 (1：橘紅；2：桃紅；3：橘黃)，並記錄株高、穗長、莖粗、分枝數、單株穗部鮮重、單株穗部乾重、單株籽粒重、脫粒率 (%) 等性狀。目前已知脫粒率為主導臺灣藜籽實產量決定性狀之一，若欲進一步釐清籽實產量及其他性狀之相關性，則需持續觀察試驗已取得足夠資料，並同時探討適作時期及經濟栽培模式。
The current applied local djulis (Chenopodium formosanum Koidz) strains are all highly heterogenous. Their irregular traits makes economic cultivation harder. In this research, we develop djulis gerplasm, reproducing seeds of collected strains, and investigating their on-field traits. So far, we have collected 20 accessions from Taitung, Hualien and Pingtung. According to the polymorphism of spike colors, we preliminary organize serial number into 1-3 more detailed catalog (1 as orange-red, 2 as peach-red and 3 as orange yellow), and traits like plant height, stem length, degree of lodging, spike length, spike weight, number of branches and shelling rates were also recorded. So far we’ve found that degree of lodging to be one of the yield-determined traits. To declare the relation between seed yield and other traits, continuing observation and further investigation are required, as well as the discussions of suitable cropping period and economic cultivation mode.
