摘要

水稻台農糯73號是由稉糯台梗糯1號與稉稻台稉16號，在1992年進行雜交，在2004年登記命名，育種年限長達12年◦在6個代表國內水稻栽培環境之地點進行2年4期作的區域試驗，以台稉糯1號為對照品種，相較結果顯示台農糯73號之生育日數第一期作平均120天、第二期作108天，均較對照品種晚3天；穗重平均在2.0g以上，千粒重平均約28g，屬於大穀粒之穗重型品種；平均稻穀產量第一期作6,876 kg/ha，第二期作4,627 kg/ha，相較對照品種增產10%以上，而且抗倒伏能力、耐肥能力、穀粒脫粒性及植株後期老化速度都優於對照品種；加工成年糕及麻煙糬，儀器測定或人工品評之咀嚼性都優於對照品種◦在生物性抗性檢定上，對葉、穗稻熱病具有中等抵抗性，對褐飛蝨的抗性也優於對照品種，唯對白葉枯病、紋枯病、斑飛蝨、白背飛蝨及二化螟蟲等病蟲害抗性與對照品種無顯著差異存在，在栽培時要注意防治◦

A new japonica type waxy rice variety was developed after more than 12 years of breeding by crossing the female Taikeng Waxy No.1, a Japonica glutinous rice variety, with the male Taikeng No.16 in 1992, and was named and registered as Tainung Waxy No.73 in 2004. During the regional yield trails, it was planted in 6 cultivated areas for 4 crop seasons using Taikeng Waxy No.1 variety as a control. The results showed that the average growth period of Tainung Waxy No. 73 was 120 days in the first crop season and 108 days in the second crop season, which were 3 days longer than control at both seasons. The new waxy rice was a heavy-ear variety with grain weight of 2 g per panicle and the average weight of 28 g per 1000 grains. The average grain yields of Tainung Waxy No. 73 were up to 6,876 kg and 4,627 kg per hectare for the first and the second crop season, respectively, about 10% higher than control. This new variety has better characteristics of lodging, shattering and stem stalk vigor than the control. The chewing of sticky rice cake and mochi making by Tainung Waxy No. 73 were also better than the check variety according to the artificial and personal pasting tests. The Tainung Waxy No. 73 displays medium resistance to leaf and panicle blast diseases, but showed susceptibility or moderate susceptibility to sheath blight, bacterial leaf blight, brown planthopper, smaller brown planthopper, white backed planthapper, and strip stem borer. Attention should be paid to prevent the pest damage during cultivation.
