為瞭解台南白自交系與外來種源自交系間之F1雜種其產量潛能之表現,以台中地區之台南白自交系(TNW A)與7個外來種源自交系間之F1雜種及自然授粉之台南白族群為對照種,分別於1995年春(3月28日)、夏(5月8日)、秋(9月4日)及冬季裡作(10月26日)於農試所試驗田進行試驗。結果顯示台南白自交系與外來自交系種源之F1雜種後裔,如TNWA×CML98、TNWA×CML93及TNWA×CML76等其產量在四個不同期作環境下均表現較台南白族群高產,同時也具有較大之雜種優勢,顯示外來種源在產量的改良上有應用價值,但鮮食用品質仍有待進一步調查。
The objective of this study is to evaluate the heterosis and yield potential of F1 hybrids as for green corn among Tainan-white and exotic inbred lines in maize. Seven F1 hybrids and one open-pollinated Tainan-white (TNW) population (check) used as materials were evaluated in Taiwan Agricultural Research Institute at four crop seasons of 1995. The results showed that some F1 hybrids among TNW inbred line and exotic inbred lines (as CML98, CML93 and CML76) produced higher yield than that of the open-pollinated TNW population in ear fresh weight and grain dry weight. Heterosis existed among TNW inbred lines and CML76, CML93, CML98. However the eating quality for green corn needs to be further investigated.
