中文摘要：
以飞船搭载甜瓜品种HM1-3及其对照（CM1-3为试材，通过地面自交繁殖，调查了SP1代不同诱变株甜瓜的果形指数、雌花率、维生素C含量、硬度、有机酸含量、单果重、含水量、果肉厚度、还原糖含量以及叶面积等10个指标，找出有利变异的突变体。结果表明：叶面积、单果重、硬度、果皮厚度、有机酸含量有显著性变异，维生素C含量、还原糖含量、含水量以及果形指数无明显变化；初步得到21株有利变异单株，其中，HM1-3-4雌花率、果形指数、叶面积、单果重等指标与对照相比差异极显著。
英文摘要：
Using the spacecraft carrying melon varieties of HM1-3 and its control CM1-3 as the materials,ten indexes of the different mutation strains of SP1 generation after self pollination,including fruit shape index,rate of female flowers, VC content, hardness, acid contents and fruit weight, water content, sarcocarp thickness, sugar contents and leaf shape index were analyzed,the main purpose was to looking for the positive advantageous variation of mutation. The results showed that the leaf area, fruit weight, hardness, sarcocarp thickness, acid contents had significant variations, however VC content,sugar contents,water content and fruit shape index did not showed significance variance; compared with CM1-3, twenty-one plants of HM1-3 had moderate variation, and rate of female flowers, fruit shape index,leaf area and fruit weight of HM1-3-4 had significance variance.
