| ABCTERACT: This study was conducted during the period from 2012 to 2014 for improving the productivity and fruit quality of local resources of sweet melon by increasing their homogeneity through inbreeding and selecting the best individual genotypes during four successive generations to produce inbred lines was the aim of this investigation. Significant differences between the base populations and selected inbred lines were observed for all studied traits. The round fruits were observed in Bm920, Si819, Bm922 and Bm923 (0.88< fruit shape index < 1.1). Twelve out of 21 genotypes had fruits with cylindrical shape (1.1< fruit shape index < 1.5), while the remaining five inbred lines were oblong shape (1.5< FSI). Concerning the mean values of selected inbred lines ranged from 5.57 to 23.86 ton/feddan and the highest values, i.e., 23.68, 15.03 and 13.2 ton/feddan were observed for Gs48, Kb613 and Fb25, respectively. Estimates ofcoefficient of variance (C.V %)values in the new selected inbred lines (C4) for the studied traits revealed higher homogeneity than base populations in all traits viz., Si819 and Bm924. Also, each of Bm920, Bm923, Si818, Si817, Fb25, Fb24, Ab12, Gs48, Ai511, Kb614 and Qi715 were homogeneous in all traits except average fruit weight, while Da1227 was homogeneous in average fruit weight, seed cavity diameter, flesh thickness and fruit shape index. These new inbred lines are enough homogeneous and could be considered as new inbred lines of sweet melon. | ||||
