Abstract
GCA and heterosis of different hybrids were studied by top-cross for seventeen pumpkin inbred lines.The results showed that weight of single fruit GCA of 129 and Sugar content GCA of 053 are highest in seventeen pumpkin inbred lines.129×031 has highest index of heterosis and relative heterosis in eleven hybrids.The weight of single fruit heterosis of pumpkin is outstanding,but sugar content heterosis of pumpkin is not outstanding,even negative result.
