摘　　要：以16份薄皮甜瓜为试材,采用方差分析和线性回归分析,研究不同甜瓜种质之间的差异性及果实性状间的相关性。结果表明,甜瓜果实长度变化幅度最大,种子长度和宽度变化幅度最小;果实宽度变异系数最小为6.92%,单瓜重的变异系数最大为20.45%。小区产量与果实长度、种腔长度和果形指数呈极显著正相关,与果实宽度呈显著负相关;单瓜重与果肉厚度、果实长度、果实宽度、种腔长度呈极显著正相关,与果形指数和种子长度呈显著相关。结果说明薄皮甜瓜的单瓜重遗传力低,易受外界环境的影响。育种中以单瓜重和果形为目标,不仅要注意果实长宽度和果肉厚度的选择,更要注意栽培措施的改进。Sixteen muskmelons were used as test materials to study the differences between different muskmelon germplasms and the correlation between fruit characters by variance analysis and linear regression analysis.The results showed that the variation range of fruit length was the largest,the variation range of seed length and width was the smallest,the variation coefficient of fruit width was 6.92%,and the variation coefficient of single melon weight was 20.45%.Plot yield was significantly positively correlated with fruit length,cavity length and fruit index,and negatively correlated with fruit width;single melon weight was significantly positively correlated with pulp thickness,fruit length,fruit width and cavity length,and significantly correlated with fruit shape index and seed length.The results showed that the heritability of single melon weight of muskmelon was low,and it was easy to be affected by the external environment.In breeding,we should not only pay attention to the selection of fruit length and width and pulp thickness,but also pay attention to the improvement of cultivation measures.
