摘要

水稻新品種桃園6號（Taoyuan No. 6, TY6）原品系代號為桃園育10310605號，係以具備芋頭香氣、抗稻熱病之‘臺稉4號’為母本，與產量高且適應性廣，抗稻熱病、穀粒飽滿、碾糙率高之‘臺稉14號’為父本進行雜交，雜交後代採混合育種法於有機栽培田進行選育，透過環境自然汰選優良單株，並於F_6世代選出桃園育10310605號品系，經過有機觀察試驗、有機初級產量比較試驗、有機高級產量比較試驗、區域試驗及各項檢定，並於2021年7月命名審查通過。‘桃園6號’係具有適合有機及友善栽培的中晚熟品種且產量穩定、株型矮、抗倒伏、分蘗能力好、穗短、一穗穎花數少並有淡淡芋頭香味；具備稻熱病之中等抗性等特性，惟對於紋枯病及稻飛蝨等病蟲害不具抗性，應注意避免施用過多氮肥；脫粒率較高與稻穀不耐室溫儲藏，則需掌握收穫時機，並以低溫冷藏。

Taoyuan No.6, a new rice variety, was originally named TYR10310605. It was selected from the progenies of the female parent "Taikeng No. 4" crossing with male parent "Taikeng No. 14". Taikeng No. 4 has the aroma of taro and is resistant to rice blast. Taikeng No. 14 has high yield, wide adaptability, resistant to rice blast, and high brown rice percentage. The bulk method was used to select the segregating individuals in the organic cultivation field, and the excellent individual plants were naturally selected by the environment, and TYR10310605 was selected in the F6 generation. After observation test, prelininary yield comparison trails, and advanced yield comparison trails of organic practices, as well as, regional yield trials. Finally, the excellent line was named in July 2021. 'Taoyuan No. 6' is a mid-late-maturing variety suitable for organic and friendly environment cultivation, with stable yield, lodging resistance, good tillering ability, and taro fragrance, moderate to rice blast. However, it does not have resistance to sheath blight, rice planthopper and other diseases and insect pests. Farmers should avoid excessive fertilizer application, and pay attention to harvest time and low temperature storage.
