Abstract
The experiments were carried out at the private Farm, in Wadi EL- Natroun, Beheira Governorate Egypt during 2015 to 2018 to produce promising hybrids of colored sweet pepper suitable to protected cultivation in Egypt, and to determine some useful genetic parameters. By using pedigree selection method, seven different inbred lines were obtained after six generations of inbreeding and selection to ensure purity of these lines . from these lines seven inbred lines of sweet pepper (Capsicum annuum L.) were used as genetic materials, viz., P1,p2, p3, p4, p5, p6 and p7. In the 2015 season, the seven parental lines were sown, at flowering stage, crosses among these lines were done in all possible combinations excluding reciprocals to produce 21 F1’s. In the second season of 2016, seeds of the 21 F1 hybrids were planted to produce 21F2 seeds. In the third season of 2016/2017, all populations viz., 7 parents, 21F1’s and 21F2’s as well as the check hybrid Theresa F1 were evaluated in plastic house (16x40m) in a randomized complete block design with three replications where transplanting was done on November11th. The evaluation included the following characters a) Vegetative traits (plant height and SPAD readings ). b) Earliness traits (days to flowering date and days to first harvested fruit). c) Early yield/plant (number and weight of fruits). d) Total yield/plant (number and weight of fruits). e) Fruit characteristics (average fruit weight, length, diameter, wall thickness, pedicel length, inedible part of fruit, ascorbic acid content, and total soluble solids percentage).Duncan’s Multiple Range Test was used for the comparison among genotype means. Heterosis and inbreeding depression were estimated, as well as general and specific combining ability (GCA and SCA) were analyzed according to the analysis of half diallel crosses mating system as outlined by Griffing (1956) to estimate the different genetic parameters.
