Abstract:
Watermelon is a kind of important economic crop in the world，therefore，it has an important significance to confirm relationship between main characters of watermelon.The experiments of correlation analysis and principal component analysis of 25 watermelon varieties were studied,to clear out the relationship of quality characteristics and yield.The results showed that the node of the first flower and near skin soluble solids content had significant negative correlation;fruit weight,fruit length，fruit width and pericarp thickness had a significantly positive correlation with yield;fruit length and fruit width，fruit shape index，pericarp thickness were significantly positive correlation with yield;pericarp thickness，yield had a very significantly positive correlation with fruit width;fruit shape index and pericarp thickness were significantly positive correlation with pericarp thickness;small significantly positive correlation with the yield;central soluble solids content and soluble solids content in skin showed significantly positive correlation.Principal component analysis showed that the first three principal components of the characteristic value of the cumulative contribution rate of 87.842 0%，from the single fruit weight，soluble solids content，fruit shape index of watermelon quality and yield breeding positive selection.
