| Abstract | ||||
| This· research were carried out at the Experimental Farm 01 El-Kassassei Hort. Station, Ismailia Govemorate, during the seasons 012000 until 2003, 10 sludy the best parent can be reliable for conducting local hybrid. Four exotic genotypes and one local variety were used In this Investigation. All possible crosses were made with out rllCiprocals 10 raise F, seeds In the green hOuse condltron, end F,'s setfed to obtain F2 seeds. I All the parental genotypes and their F, and F2 generations were sown I~ open field and data were collected on fruits of individual plants. The obtained result show, that variances due to specific combining ability were higher in magnitude tha the variances of general combining ability for all studied traits. Dominant gene effect!! were controlling the economic characteristics of melon, except number of frults/ planti This was governed by both dominant and additive gene effects. The genera combining ability effects of parents revealed that P2 (P11 83227) was good combine~ lor yield components and its quality. The specifIC combined ability effects of hybrids decleared that the best specific cross combination for total yieldl fed., average fruit weight and ,nesh thickness was F, (PI x Ps) and the cross F, (P2 x Pl) was the bes combination for number of fruits! plant and total soluble solids. Heritability estimates i~ broad sense were found to be higher in magnitUde inbreeding depression had a grea~ effect on yield on yield component and its quality, while vegetative growth was noli affected by it. | ||||
