摘要
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.
