不同檢定親及族群對玉米籽粒與青割產量性狀間關係之影響

Abstract

本研究使用五個不同之玉米族群為試驗材料，藉臺農1號父母本TA3651-377及TA2808-176兩個自交系為檢定親，分別與每一族群之20個S4系統雜交，產生200個測交種（計分10群）。調查籽粒及青割產量性狀，估算外表型相關，比較不同檢定親及族群對性狀間關係之影響，並評估族群作為籽粒或青割育種材料之潛力。Five maize populations were used to determine the effects of inbred testers and populations on the relationship among grain and forage traits, and to evaluate their potential as breeding sources for grain and forage yield. Twenty S4 families from each population were crossed to two inbred lines, TA3651-377 and TA2808-176 to form ten groups of testcrosses.
