Abstract
由品種栽植期試驗結果獲知，4個供試品種除 Suparex 外早期栽種均優於晚期栽種，因Suparex 在早期對氣候反應敏感，產量不穩。平均產量以Equanex 最優，與早玉(CK)比較，早期產量提高21.8%，晚期提高25.4%，合格率亦分別提高92.8%及61%。在引種試驗當中選出Onion 5783, PSR8489, FMX-250及XPH6069等品種，地方試作中新品種 63001, 63002 產量及品質穩定，擬繼續作試驗。利用生長劑益收素 (Ethrel)處理試驗，評估可行性結果，低濃度（如1600倍、1200倍液）處理優於高濃度處理，其產量、品質均佳。台農選三號原原種繁殖採獲種子26.5公斤，純度佳，另設擴大示範區，其產量已比早玉(CK)品種提高12%，合格率亦提高到21.22 %，均獲好評。
Based on the trial results of this year, the early plantings of four tested cultivars except cv. Suparex were superior to the late plantings. The yieldings of cv. Suparex were unstable due to the sensitiveness to the climate of early planting. The average yield of cv. Equanex showed the highest among the four cultivars tested. Compared with cv. Early Grano, cv. Equanex increased 21.8% at early planting and 25.42 at late planting, and also inereased 92.8% and 61% of pass grade percentage, respectively.
From the trials of newly introduced varieties, Onion 5783, PRS 8489 and FMX-250 were selected. From the regional trials, cv. 63001 and 63002 were suggested to conduct advauced testings due to the stable performances of yielding and quality. Feasibility study of applying ethrel, low concentration (1600x or 1200x solution) treatments were superior to higher ones.
26.5 Kg quality foundation seeds of cv. Tainung 3 Selected were multiplicated, and good reputations were also gained from the large-sized demonstration fields of cv. Tainung 3 Selected, because of 12% higher yielding and 21.22% higher percentage of pass grads compared with cv. Early Grano.
