Abstract

This study is conducted in order to select the varieties that can supplement problems related with organic cultivation of bulb onion (Allium cepa L.). 15 test varieties were selected considering rural preference, breeding line, breeding company, open-pollinated cultivar, F1 hybrid cultivar of either domestic or foreign products. Onion varieties were assessed in 5 criteria which are : growth of plants in low temperature, freezing injury resistance, resistance to physiological disorder such as bolting and doubled bulb, lodging index during harvest, and marketable yield. As a result, e-Joeun, Katamaru, Pop, Art, Singihan among F1 hybrid cultivars and Changnyeongdaego, Seouldaego, and Chunjujunggo among open-pollinated cultivars were selected as more suitable varieties for the organic cultivation. Although Sunpower cannot be selected in varieties those are suitable for organic cultivation, it showed excellent traits in the bulb characteristics. No significant differences were found between open-pollinated cultivar and F1 hybrid cultivar except growth of plants in low temperature (plant sheath diameter) and lodging index during harvest (May 24th). And no significant differences were recognized between domestic varieties and foreign varieties except missing plant ratio after wintering.

본 시험은 유기재배에 적합한 양파 품종 선발을 통해 유기재배 시 발생할 수 있는 문제점을 보완하기 위해 수행되었다. 농가 선호도, 육성계통, 육종회사, 고정종, 교배종, 국내종, 외국종 등을 고려하여 15개 품종을 선발하여 시험을 수행하였다. 각 품종들은 저온생장성, 동해 저항성, 추대, 분구 등 생리장해에 대한 저항성, 수확기 도복률 및 상품 수량 등 5개 영역에서 평가되었다. 교배종에서는 e-조은, 카타마루, 팝, 아트, 신기한 등이, 교배종에서는 창녕대고, 서울대고, 천주중고 등이 유기재배에 적합한 품종으로 선발되었다. 비록 적합한 품종으로 선발되지는 못했지만, 선파워는 구 특성에서 좋은 결과를 보였다. 고정종, 교배종간에는 저온생장성(엽초경), 수확기 도복률(5월 24일)을 제외한 전 영역에서, 국내종, 외국종 간에는 월동 후 결주율을 제외한 전 영역에서 유의한 차이가 발견되지 않았다.
