臺灣藜品種(系)選育

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。本研究目的在於建置臺灣藜種原庫、繁殖蒐集地方品系種子，並於田間進行性狀調查。目前已於臺東、花蓮及屏東等地蒐集20 個地方品系。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、分枝數、單株粒重等性狀。期能選育出早熟、矮株、高單株粒重之臺灣藜新品種。 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, spike length, number of branches and grain weight were also recorded. We hope to select new djulis varieties with short mature period, short plant height and high grain weight.
