食用紅甘蔗品種選育

Abstract

為提高本省食用紅甘蔗品質及產量，進行品種選育工作，從全省栽植食用紅甘蔗產區所搜集到21個地方種，於87年度在本場實驗農場進行觀察及選育結果，計選出10個農藝性狀表現優良選系，於88年度在埔里鎮籃城里進行第一年產量比較試驗，結果選出台中選系10、6、2及9號之產量表現較佳，比埔里地方種增加6.7%~10.9％。其中以台中選系10號之表現最佳，具有平方公尺莖數多、產量高（121,l06 kg/ha)，中問5節長度長（42.9 cm）及總可溶性固形物高（19°Brix）等優良性狀，俟89年度完成第2年試驗後擬參加全省性區域試驗。 In order to increase the unit yield and quality of fresh edible sugarcane, the 21 fresh edible sugarcane local lines were collected from all over the Taiwan, Ten elite lines was selected in this station in the 1998. The fist year yield trail of those 10 new lines was conducted in Puli, Nantou county in the 1999. The result showed that the average yield of Taichung selection No. 10, 6, 2 and 9 is 6.7-10.9% higher than that of check variety “Puli Local”. Taichung selection No.10 have the highest plant number, highest yield (121,106 kg/ha), the longest middle 5-node length (42.9 cm) and highest total soluble solids (19.1 °Brix). After the second year yield trial, those line will joint the regional yield trial in 2001.
