飼料玉米「台南24號」之育成及品種特性

Characteristics and Breeding of a New Feed Corn Variety "Tainan No. 24"

摘要


飼料玉米台南24號為三系雜交品種。原品系代號為PGH 96-2,自民國95年起進行新品系組合力檢定試驗,再經新品系比較試驗、新品系區域試驗、穩定性分析、氮肥試驗、栽培密度試驗、籽實品質分析及抗病性檢定等試驗,於民國98年命名為台南24號。台南24號的植株高大強健,抗倒伏性強,適合機械收穫。強抗露菌病和莖腐病。試驗期間其銹病發生率亦較台南20號低。株高在春作約270公分,秋作約265公分。成熟期在春作為116〜120天,秋作為130〜140天,為晚熟品種。穗長約22公分,乾籽實成份分析為粗蛋白質含量9.68%,粗脂肪含量5.15%,粗纖維含量3.0%,澱粉含量64.13%。每公頃乾籽實產量為約7,500〜8,000公斤。另台南24號植株高大強健,莖稈粗狀,葉片濃綠寬大,抗病性強,其每公頃植株鮮重達55,000〜60,000公斤,故亦可兼作飼養乳牛之青割玉米。
