Abstract
1. 二十二個品種，播種期提早，產量及結球率固可提高，但分球率及抽苔率亦相對增多，對洋蔥品質影響甚大；過遲播種者，雖分球率及抽苔率降低，但蔥球不大，產量減少，亦屬不適。
2. 早熟品種之播種適期，以九月下旬至十月中旬之間為最佳，九月中旬以前播種，不特育苗時間常遇颱風豪雨之害，除用特殊設備覆蓋外，不易育成。晚熟品種，如Red Creole, White Creole等之播種適期，在南部以十月下旬為最適，臺中以北為十月中旬。過早播種，分球抽苔率極高，鱗球形質劣變。
3. 二十二個品種，就播種期之早晚，與產量、結球率、分球率、抽苔率之比較，合於臺灣氣候之栽培價值者早熟種有四個品種。(1)Granex (2)Early Grano (3)San Joaquin (4)Excel Bermuda，晚熟種有二個品種(1)Red Creole (2)White Creole.
4．晚熟種Red Creole及White, Creole，在生育期中，抗病力強，收穫之鱗球大小，雖不十分整齊，產量又低，但極耐貯藏，在臺灣之自然室溫下，經過炎熱漫長之暑期，腐敗率極低，為前述早熟種所不及。
5. 此外比較試驗品種中(1)Red Bermuda (2)White Grano (3)Crystal White Wax (4)Granex Hybrid(5)Texas Grano (6)Laredo 690等六品種，尚有試驗調查價值外，其餘各品種，成績極差，在臺灣無栽培經濟價值。
1. In a trial of twenty two onion varieties, it was found that, when the dates of planting were early in the season, the rates of bulbing and the yields were increased with higher yields of doubles and bolters. However, if the date of planting was too late in the season, the size of bulbs was so reduced that the yield was apparently decreased, although the rates of doulbling and bolting were also lowered.
2. The optimim dates of planting early harvesting varieties of onion were found between the last of September and the middle of October. Planting seeds before middle of September was dangerous because of possiblility of Typhoone damage, unless there is proper protection provided to seedbeds. The optimum dates of planting late harvesting varieties of onion, such as Red Creole, White Creole, were near the last of October in the southern part of the island, and in the middle of October in the northern part of the island.
3. Among the twenty two onion varieties tested, based upon the performance in relation to time of planting, yield, rate of bulbing and bolting habit, the following varieties were adapted to Taiwan climatic conditions:
Early harvesting varieties: Granex, Early Grano, San Joaquin, Excel Bermuda.
Late harvesting varieties: Red Creole, White Creole.
4. Red Creole and White Creole were resistant to diseases, yet low yielding with small bulbs not uniform in shape. However, these varieties were excelent keepers and could be stored over summer with very low rates of losses. The other varieties tested were all poor keepers.
5. Among the varieties tested, the following were partially adepted to Taiwan conditions, and may receive further attention: 1) Red Bermuda, 2) White Grano, 3) Crystal White Wax, 4) Granex Hybrid, 5) Texas Grano 502, 6) Laredo 690.
The varieties which did not show promising in the trial were as follows: 1) California Early Red, 2) Stockton G-36, 3) India Red Globe, 4) Yellow Sweet Spanish, 5) White Portugal, 6) Early Yellow Globe, 7) Stockton Yellow Globe, 8) White Babosa, 9) Ebezer Yellow Globe, 10) Red Torbeda.
