摘要

茭白筍具有衛生營養及美味可口等優點，為一般消費者所喜愛的夏季蔬菜，八０年代本省主要栽培品種為青殼早生種，其春作出筍期較晚，且不感染株及黑心產生率較高，影響品質與收益，後來逐漸有地方品種或農民自選種的產生；但因那些品種大部份從變異植株選出，未經審慎考種，其來源不清、特性未明，經常發生不明病變或產量不穩定現象。因此，選拔早生、豐產、不感染株及黑心產生率低者，視為一項重要課題。本場於1992年在本省主要茭白筍產區埔里地區由青殼種族群中選拔優良單株，利用營養系選種法繁殖，產生台中一號（原品系名稱為台中選育C-26）。本品種除具有育種目標與特性外，其嫩筍產量比傳統青殼早生種，春作增產19.4%、秋作增產17.5%，亦比農民自選敢當早生種，春作增產6.9%、秋作增產5.3%。出筍期比青殼早生種，春作提早23天、秋作提早6天，亦比農民自選敢當早生種，春作提早4天、秋作則差異不明顯，本品種不感染株及黑心產生率均比其它品種系為低。台中一號（台中選育C-26）新品種兼具早生、豐產、口味佳等多項優良特性，適合水源豐富地區雙期作栽培。

Coba (water bamboo), Zizania latifolia, is a popular summer season vegetable for its high nutrition and delicious taste. In 1990, the major cultivated variety is ”Green shell early”, but the late spring bamboo production period and high healthy plant and smut production rate, thus affecting the quality and yield of coba production. The local or farmer selected varieties are most of unknown sources and characteristics resulted in unstable yielding and disease occurrence. Due to the above reason, the station began a series of selection project to select the early, high yielding, low healthy plant and smut production rate of variety. The elite individual plants was selected from ”Green shell” variety cultivated at Puli areas, and multiplication by mother stock selection. The selection line Taichung C-26 was named and registered as Taichung No. 1. The bamboo yield of Taichung No. 1 is higher than that of ”green shell” by 19.4% and 17.5% at spring and fall seasons, respectively. It also higher than that of ”kang-dang” variety by 6.9% and 5.3% at spring and fall crop seasons, respectively. The bamboo shoot production date is earlier than that of ”green shell” by 23 days and 6 days, than that of ”kang-dang” by 4 days and no difference at spring and fall crops season, respectively. The Taichung No. 1 have low healthy plant and smut production rate than check varieties. The new variety ”Taichung No. 1” possesed earlier maturity, high yielding and good taste characteristic is suitable for growing in paddy-field areas for two seasons production.
