Abstract: 【Objective】To reveal the effects of main economic characters and pollen characters on the yield and characters of seed melons and to guide seed melons breeding.【Methods】 36 seed melon varieties and materials were used as research objects，and under normal cultivation conditions，the main economic characters（total number of grains per melon，grain weight，100-grain weight，grain girth）and pollens traits（polar axis P and equatorial axis Eand the ratio of polar axis to equatorial axis P/E according to the result of a measurement）were used for correlation analysis and partial correlation analysis.【Results】The largest coefficient of variation was the number of seeds per melon，followed by the weight of seeds. There was a significant positive correlation between grain number and weight，a significant negative correlation between grain number and 100-grain weight and mean grain perimeter，and a significant positive correlation between grain number and pollen polar axis length P and equatorial axis length E；Pollen polar axis length P and equatorial axis length E were negatively correlated with seed size and girth.【Conclusion】Higher grain weight and 100-grain weight could be obtained by selecting smaller pollen grains in seed melon breeding. In order to select a variety with a large number of seeds per melon，it is necessary to select a small seed material. The polar-axis length and equatorial circumference of polar-axis of polar-axis of pollen and the smaller polar-axis length of equatorial axis of polar-axis of pollen should be selected for breeding large-grain varieties. This finding from this study provides a scientific basis for breeding new varieties of seed melons.

摘要： 【目的】为揭示打瓜主要经济性状和花粉性状对打瓜籽粒产量和性状的影响，指导打瓜育种。【方法】以36份打瓜品种和材料为研究对象，在正常栽培条件下，对其主要经济性状（单瓜籽粒总数、籽粒重量、百粒重、籽粒周长）和花粉性状（花粉赤道面观的极轴长P和赤道轴长E以及根据测量结果计算极轴长与赤道轴长的比值P/E）进行相关及偏相关分析。【结果】各性状中变异系数最大的为单瓜籽粒数，其次为籽粒重量；籽粒数和籽粒重量呈极显著正相关，籽粒数与百粒重、籽粒周长均值呈极显著负相关，籽粒数与花粉极轴长P、赤道轴长E呈显著正相关；花粉极轴长P、赤道轴长E和籽粒大小、周长均值呈极显著负相关。【结论】打瓜育种中选择较小的花粉颗粒，可获得较高的籽粒重量和百粒重；选育单瓜籽粒数多的打瓜品种则需要选择小籽粒材料；选育大籽粒类型的品种，可参考花粉极轴长和赤道轴长，选择花粉极轴长和赤道轴长较小的材料。本研究为打瓜新品种的选育提供了科学依据。
