摘　　要：按双列杂交设计,用Griffing分析方法,对6个丝瓜自交系的10个主要经济性状的配合力及遗传参数进行分析。结果表明:各性状的一般配合力方差和特殊配合力方差均达到极显著水平。P3和P6自交系的综合性状较优,可在育种中直接利用;P3×P4等4个组合具有较强的杂种优势,有一定的增产潜力。在育种工作中,对丝瓜第1雌花节位等3个性状宜早代选择,而对可溶性糖含量等其它性状应进行晚代选择。The 6 luffa inbred lines have been tested with the design of diallel crossing of griffing method to study on combining ability and its genetic parameters of 10 characters.The result indicated that the variance of both general combining ability and specific combining ability on all characters were very significant.The lines of P3 and P6 with the better comprehensive characters which can be directly used in Luffa breeding program;The 4 combinations of P3,P4 etc.with higher heterosis had potentiality of increasing yield production. In Luffa breeding program, the 3 characters such as first note of female flower should be selected earlier and other characters such as content of soluble sugar should be selected later.
