苦瓜新品種‘花蓮5號’之育成--育成經過-4 - 農業知識入口網

（二）品系比較試驗
2005年春作品系比較試驗結果如表五，以品系WB34之小區產量最低，而品系WB33、WB35、WB36 (花蓮5號)表現較佳，WB33與WB36之雌花率顯著較高，WB33之小區產量23.5 kg，單株結果數299個，皆為顯著最高。2005年夏作品系比較試驗結果如表六，以品系WB35之小區產量最低，品系WB33、WB34及WB36三品系表現較佳，其中WB33之雌花率、小區產量25.5 kg及單株結果數301個，皆為顯著最高，但WB36之小區產量亦為顯著最高，綜觀二個期作以WB33及WB36表現較佳，故選入區域試驗。
