Abstract
The experiment was carried out in the Field Dept. of Hort. & Landscape Design, College of Agric. & Forestry , Mosul University , during two growing season 2009 and 2010 , was included evaluation of eight varieties of Melon viz , (Alkosey , Hafz nafsah , Sherein , Crawly , Al-Mostkabil (Syrian) , Ananas , Golden Beauty and Hales Best Jumbo) by using Randomized Complete Block Design R.C.B.D. with three replications. To determine genetic , phenotype variations , heritability , expected genetic advance , phenotypic and genotypic correlation for studied characters. Combined analysis results exhibited significant differences that the varieties between the two growing seasons for all the studied characters. A significant varieties x year interaction effect was found for all the studied characters except the plant height and no. of seeds/fruit. The results showed that the varieties were differed significantly for all the studied characters , Hafz nafsah variety was highly superior for seeds yield and Alkosey variety for total yield. There was a high genetic variation for plant height , date maturity and no. of seeds/fruit. High heritability for date maturity , no. of fruits/plant , average wt. of fruit , seeds yield and total yield , which means that most of the phenotype variation between varieties was due to genetic. High expected genetic advance for no. of fruits/plant , average wt. of fruit , no. of seeds/fruit , seeds yield and total yield. The higher phenotypic and genotypic correlations were found between average wt. of fruit and total yield.
