洋蔥新品種台南一號之育成

張明聰 余合

摘  要

利用Red Creole和Early Grano二品種間的什交,經十餘年的時間由其後代選出一極優良的品種,南改系一號(10-170-3-4),極適于本省南部地區種植及採種,經65年3月19日由洋蔥新品種命名委員會審查通過,命名為台南一號,此為本省第一個由國人自己培育成功的品種,該品種豐產,極耐貯藏,又可自行採種,因此本省洋的栽培事業將因它的培育成功可不再依靠國外進口種子。


Release of An Onion Cultivar “Tainan No. 1”

Ming-Tsong Chang, Her Yu

Summary

Onion has been grown for more than 20 years in Taiwan and yield was increased gradually by improvement in cultural practice.  Since the harvest time was approximately one month earlier than Japan, it has become one of the important fresh vegetable export to that country.  Because of the environmental limitation in onion production, all cultivars used in this country were introduced from abroad and the only adapted cultivar is Early Grano.  However, this cultivar was not able to produce seeds for propagation.  It was necessary to import seeds from foreign country.  So that, it was difficult to guarantee the seeds quality and seeding time.  These would makes a heavy loss to the government.

In view of the scarcity in adaptable cultivars, Tainan DAIS began an onion breeding program which emphasized in storage quality, bulb and seed yield.  Tainan No. 1 was released after 10 years of selection from a cross between Red Creole and Early Grano.  It was evaluated and denominated by the Committee in March 19, 1976.  This was the first onion cultivar ever bred and released in this country.  Tainan No.1 is good in yield and storage quality and is well adapt to natural condition of southern Taiwan.  Consequently, propagation of onion in Taiwan will no longer depend on imported seeds after the release of this cultivar.
