对31个南瓜自交系（亲本）和127个杂交组合（ F1）进行了配合力及杂种优势研究。结果表明，在31个自交系中，果实的单瓜质量、纵径、横径、肉厚、固形物含量一般配合力最高的分别为396、456、467-1、467-1、旋复。在127个杂交组合中，北观×长2的单瓜质量、果实纵径和肉厚的特殊配合力在全部杂交组合中均为最高，横径、固形物含量特殊配合力最高的分别为042-1×467-1、009-1×467-1。另外，供试的南瓜杂交组合（ F1）杂种优势表现比较明显。在85个杂交组合中，单瓜质量的超中优势与超亲优势为正值的分别为41，27个，占全部杂交组合的49％和32％；果实纵径的超中优势与超亲优势为正值的分别为24，7个，占全部杂交组合的28％和8％；果实横径的超中优势与超亲优势为正值的分别为26，32个，占全部杂交组合的31％和38％；果实肉厚的超中优势与超亲优势为正值的分别为42，28个，占全部杂交组合的48％和33％；果实固形物含量的超中优势与超亲优势为正值的分别为37，15个，占全部杂交组合的43％和18％。
對31箇南瓜自交繫（親本）和127箇雜交組閤（ F1）進行瞭配閤力及雜種優勢研究。結果錶明，在31箇自交繫中，果實的單瓜質量、縱徑、橫徑、肉厚、固形物含量一般配閤力最高的分彆為396、456、467-1、467-1、鏇複。在127箇雜交組閤中，北觀×長2的單瓜質量、果實縱徑和肉厚的特殊配閤力在全部雜交組閤中均為最高，橫徑、固形物含量特殊配閤力最高的分彆為042-1×467-1、009-1×467-1。另外，供試的南瓜雜交組閤（ F1）雜種優勢錶現比較明顯。在85箇雜交組閤中，單瓜質量的超中優勢與超親優勢為正值的分彆為41，27箇，佔全部雜交組閤的49％和32％；果實縱徑的超中優勢與超親優勢為正值的分彆為24，7箇，佔全部雜交組閤的28％和8％；果實橫徑的超中優勢與超親優勢為正值的分彆為26，32箇，佔全部雜交組閤的31％和38％；果實肉厚的超中優勢與超親優勢為正值的分彆為42，28箇，佔全部雜交組閤的48％和33％；果實固形物含量的超中優勢與超親優勢為正值的分彆為37，15箇，佔全部雜交組閤的43％和18％。

The experiment studied 31 pumpkin inbred line(parent)and 127 hybrid combinations(F1)on com-bining ability and heterosis .The result indicated that the highest general combining ability of the single fruit weight and longitudinal diameter and transverse diameter and fruit pulp thickness and soluble solid content of 31 inbred lines were 396,456,467-1,467-1 and Xuanfu,respectively.The highest special combining ability of the single fruit weight and fruit vertical diameter and the meat thick of 127 hybrid combinations was Beiguan ×Long2 and the high-est special combining ability of the transverse diameter and the soluble solid content of 127 hybrid combinations were 042-1 ×467-1 and 009-1 ×467-1.In addition,pumpkin hybrid combinations(F1)have more obvious heterosis performance .The number of variety of the positive mid-parent and over-parent heterosis of the single fruit weight were 41 and 27 ,accounting for 49%and 32%of 85 hybrid combinations .The number of variety of the positive mid-parent and over-parent heterosis of longitudinal diameter were 24 and 7 ,accounting for 28% and 8%of 85 hybrid combinations .The number of variety of the positive mid-parent and over-parent heterosis of transverse diameter were 26 and 32 ,accounting for 31%and 38%of 85 hybrid combinations .The number of variety of the positive mid-par-ent and over-parent heterosis of fruit pulp thickness were 42 and 28 , accounting for 48% and 33% of 85 hybrid combinations .The number of variety of the positive mid-parent and over-parent heterosis of soluble solid content were were 37 and 15 ,accounting for 43%and 18%of 85 hybrid combinations .
