Abstract: The root tips of germinating seeds were used as materials and chromosome counting and karyotype analysis were performed in eleven melon relative plants and one wild melon plant. The results showed that chromosome number in somatic cells of most samples were 2n=24, except one accession C.anguria with 48 chromosomes and one accession C.dipsaceus with 44 chromosomes in somatic cells; The karyotypes were divided into five types: C.bisexualis is 2n =2x=2 M+14 m +10 sm,C.hystrix is 2n =2x=24 =24 m,C.dipsaceus and C.prophetarum 2n =2x=20 m +4 sm,C.myriocarpus, C.ficifolius, C.africanus and C.pustulatus is 2n =2x=12 m +12 sm,C.zeyheri is 2n =2x=24 =2 M +18 m +4 sm, and there were no satellites detected in hemorphological observation of chromosomes.
