The external feature of sweet melon (Cucumis melo var. reticulatus) is considered a limiting factorthat affects consumer preference, categoriza¬tion and grading of melon fruits and hence marketing of the produce. It includes shape and netting of the fruit and color of the outer skin. Although, netting is among the factors of economic value in the melon international trade, information concerning netting is mostly lacking. Pitrat et al. (2000) used the netting criterion for classifying the different melon species. The fully netted fruits are much preferable and believed to be firm and sweet. Heavy netting is dominant over smooth (Mohamed, 1997). Lumsden (1914) found a polygenic mode of netting inheritance, indicated by the segregation in the F2 and F3 progenies of a cross between plants of netted and smooth fruits. Heritability of netting is high, and high netting is negatively affected by low calcium content in the soil (Swamy, 1985). The main objectives of the present study were to estimate heritability of the different parameters of netting, to estimate association of netting with other yield and quality attributes of melon and to determine the chemical composition of the netting callus. Work described here was conducted at the National Institute for Promotion of Horticultural Exports and Faculty of Engineering and Technology, University of Gezira, Sudan, during 1997-2004. Thirteen lines representing different melon types were grown twice at the University of Gezira Research Farm, during the period 1997-1998
