甜瓜主要农艺性状与品质性状的配合力分析

Combination Ability Analysis on Agriculrural Characters and Quality Characters in Muskmelon

以6份甜瓜自交系为亲本进行完全双列杂交,采用Griffing方法Ⅱ配制杂交组合15个,对甜瓜6个亲本和15个杂交组合果实的单果重、种腔直径、果实纵径、可溶性糖含量、有机酸含量、维生素C含量一般配合力和特殊配合力进行分析。结果表明:亲本M_5、M_2的一般配合力较高,是十分优良的母本,而M_4、M_6是表现较好的父本。组合M_4×M_5、M_2×M_6、M_5×M_6、M_2×M_4的特殊配合力较高,属综合性状优良的组合。该结果将为甜瓜杂交育种的亲本选择和选配提供依据。

15 crossing combinations were combined from 6 inbreds according to the complete diallel crosses of Griffing method ⅡμThe GCA（ general combining ability） and SCA（ special combining ability） of 6 main fruit characters（single fruit weight, species of cavity diameter, vertical length of fruit, content of soluble sugar, content of total acids, content of vitamin C） of Muskmelon were analyzed with 6 inbreds and 15 hybrids. The main results were as follows：The inbreds of M5 and M2 with higher GCA, are two very good female parents, and M4 and M6 are good male parents. The hybrids of M4 × M5 ,M2 × M6 ,M5×M6 M2×M4 with higher SCA were good combinations with fine comprehensive quality traits.
