Abstract
三倍體無子西瓜由Kihara等首先研究成功後，現已成為商品。在臺灣大型三倍體西瓜經郁宗雄等之研究改進，現已普遍生產，並大量外銷，近年來小型西瓜風行一時，深受生產者及消費者所歡迎，但嫌種子太多，鳳山熱帶園藝試驗分所有鑑於斯，乃一方面從事三倍體小型無子西瓜之育種，一方面從事以染色體轉座方法育成少種子（Semi-seedless）之小型西瓜。
For the purpose of reducing the seed number of small-size watermelon by chro-mosomal translocation, dry seeds of Hsiao-feng variety were irradiated with5, 10, 15, 20, and 30 Kr doses of ‘y-rays. The results showed that irradiation produced some harmful effects on seed germination and the rate of seedling survival. The higher the dose of irradiation used, the more harmful effects were observed. Pollen abortions were found in some survival plants and seedling was made with plants showing semi-sterility (Table 2).t was rather difficult to obtain these seedling fruits and there were less seeds in the fruits (Table 3).
