摘　　要：为筛选西瓜抗枯萎病砧木,进行了不同砧木西瓜抗枯萎病接种实验及不同砧木嫁接苗田间长势、果实综合性状的研究。通过枯萎病接种实验,筛选出了6个高抗砧木,分别是N1、N6、H2、H5、X3与X4;在长势方面,嫁接苗明显强于自根苗,以南瓜为砧木的嫁接苗长势强于其他品种;在果实品质方面,各个品种的平均单果重差异不显著,且果型差异不大,但以H5(亲抗水瓜)、X3(大维根砧15号)和X4(勇士)可溶性固形物含量较高。综合研究认为,H5、X3和X4对枯萎病抗性较高,且长势较好,品质较优,综合表现较优。For screening root stocks of resistant to watermelon fusarium wilt,experiment of inoculation on watermelon fusarium wilt and growth,quality characters of grafted watermelon were investigated in Sanya.Selection 6 high-resistance root stocks which were N1,N6,H2,H5,X3 and X4 from 18 cultivars in inoculation experiment.The growth of grafted seedlings was better than own-root seedlings on fields.Grafted seedlings by pumpkin root stocks were best which compared with the others.In quality,there ware not significantly in average weight per fruit in different cultivars,there had the same also.but The content of soluble were high in H8,X3 and X5.H8,X3 and X5 had a good performance in Fusarium wilt resistant growth and quality.
