Abstract
64 pumpkin crosses were made from representative 16 inbred lines by multiple line cross method,of which 14 crosses were selected randomly for analysis.The results showed that there existed commonly the heterosis in crosses of pumpkin inbred lines.The mid-parent heterosis of single fruit weight were all positive,1.51 in average.The positive mid-parent heterosis of soluble solid content was present in 10 crosses,accounting for 71.43% with a mean value of 0.08.In the 16 pumpkin inbred lines,line 129 had the highest GCA for single fruit weight and line 053 the highest GCA for soluble solid content.The 16 pumpkin inbred lines were classified into 3 clusters.
