一、前言我室从1973年开始与本院遗传教研室协作进行西瓜多倍体育种工作,用0.2—0.4％的秋水仙碱溶液进行胚芽倒置浸渍和滴生长点的方法,先后诱变成红玫瑰、蜜宝、蜜玫、解放瓜、都三号、中非六个品种的四倍体(诱变方法和细胞学鉴定另文发表)。1976年从邵阳引进了邵阳402、邵阳403,从广东引进了小青皮四倍体,进行了单果选留。1978年对以上四倍体进行品比试验,对照品种为旭太和四倍体。 First, the foreword My room from 1973 with the Department of Genetics, collaborative work of watermelon polyploidy breeding work, with 0.2-0.4% colchicine solution for dip and drop of embryo growth point of the method, has mutated into a red rose , Honey, honey Mei, the liberation of melon, are on the 3rd, China and Africa, the four species of tetraploids (mutagenesis and cytological identification of another published). In 1976 Shaoyang introduced from Shaoyang 402, Shaoyang 403, from the introduction of small tetraploids in Guangdong, a single fruit reservation. In 1978 the above tetraploid ratio test, the control variety Asahi Taihe tetraploid.
