目前蔬菜生产上多应用杂种一代优势,但茄果类蔬菜靠人工去雄获得一代杂交种子成本较高。本试验试图应用化学诱变剂诱导辣椒遗传性状发生变异,以获得辣椒新品种。1 材料与方法1991年3月用0.2%秋水仙碱水溶液浸泡华椒17(1990年从武汉市蔬菜种子公司购进)种子40粒,至种了萌发两天后用清水洗净播种。播后仅长出两株幼苗,其中一株在移钵过程中死去。剩下一株幼苗生长极缓慢,5月中旬苗高 At present, the application of hybrid generation is more and more applied in vegetable production. However, it is more costly to obtain somatic hybrid seeds by solanaceous vegetables by hand. This experiment tried to use chemical mutagens to induce genetic variation in pepper to obtain new pepper varieties. 1 Materials and methods March 1991 with 0.2% aqueous solution of colchicine soak pepper 17 (purchased from Wuhan Vegetable Seeds Company in 1990) seeds 40, to the kind of germination two days after planting with water wash. Only two seedlings were grown after sowing, one of which died during the transfer of pots. The remaining seedling growth is very slow, mid-May seedling height
