Abstract: We have analyzed internode length,leaf width,leaf length,and other six traits in an F2 population of a cross between J28 -1 -4 -2(H)-2 -2 -1 and DC -4 -1 -7 -2 -1 -4 -1 -1 -1 using variance analysis,correlation analysis and path analysis.The results show that all traits,expect internode length which gives a bimodal distribution,give approximately normal distributions in the F2 population,indicating that they are controled by QTLs.The bimodal distribution of internode length ,which is different from previously reports,suggests that it is controlled by more than one gene.The correlation among all traits investigated are highly significant.Path analysis indicates that internode length has a minor effect on fruit weight.The significant correlation coeffcient between internode length and fruit weight may caused by other traits ,which suggest the internode length may not affect the fruit weight.It will provide the theory for melon short internode breeding.
