Interspecific hybridization is intensively carried out to increase the existing genetic variation and to extend of genetic bases of varieties that have biotic, abiotic stresses tolerance and also genetic studies to determine variation of nutritional characteristics in pepper breeding programs. In this study, 104 RIL (Recombinant Inbred Pepper Lines: F6) populations which generated by selfing C. annuum (Long pepper) x C. frutescens (PI281420) F6 population were used to assessment of some fruit nutritional traits. Crude oil ratios varied between 3.20% and 11.43%, crude ash ratios between 5.26% and 17.69% and crude protein ratios between 8.09% and 23.57%. Na contents varied between 106.04 and 2140.07 ppm, Ca contents between 1167.67 and 6004.13 ppm, K contents between 10419.03 and 24775.40 ppm, Mg contents between 1240.37 and 6793.53 ppm, P contents between 2125.23 and 8858.85 ppm and S contents between 1037.65 and 7691.55. Lauric acid contents varied between 0.03% and 0.92%, myristic acid contents between 0.10% and 2.93%, palmitic acid contents between 11.67% and 27.13%, palmitoleic acid contents between 0.18% and 1.67%, heptadecanoic acid contents between 0.00% and 0.53%, heptadecenoic acid contents between 0.00% and 0.25%, stearic acid contents between 1.57% and 6.79%, oleic acid contents between 7.01% and 49.98%, linoleic acid contents between 26.28%− 57.79%, arachidic acid contents between 0.12% and 1.92%, linolenic acid contents between 0.97% and 14.86%, behenic acid contents between 0.05% and 2.58%, MUFA contents between 8.58% and 51.12% and PUFA contents between 28.98% and 68.51%. Beta-carotene contents varied between 23.92 and 1547.19 mg/100 g. Interspecific hybridization in pepper has an important role in increased the nutritional properties level in hybrids. So, these results open the new world gene pool for pepper breeding, ultimately contributing to nutritional properties to new pepper varieties. • Wide variation was achieved by interspecies crossing. • Some inbred lines have better nutritional properties than parents. • Protein content, PUFA, S, P, Mn, Mg were determined as ideal properties in lines. • Variation of nutritional properties can be used for mapping of related genes and breeding.

• The highest a* and b* values were recorded for freeze drying. • Wang & Singh and Page model showed the best fitting performance. • The reactions of pepper varieties to drying methods were different. • Microwave drying was prominent for increased total phenolics. Effects of different drying methods (open-sun, shade, greenhouse, microwave (300−600 W), air-convective (60−80°C) and freeze drying) on drying kinetics, biochemical characteristics, rehydration ratio, color and total phenolic content of two different pepper cultivars (Bozok and Pinar) were investigated in this study. Significant differences were observed in biochemical traits of the cultivars and response of cultivars to different drying methods was also different. The greatest crude protein, β-carotene and lycopene values were recorded for the freeze dryer application. The greatest ascorbic acid values were obtained from freeze dryer and shade drying. Microwave drying process resulted an increment in total phenolic contents of the samples. Except for shade drying, the other methods reduced the oil contents and drying methods significantly influenced fatty acid composition of the samples. The rehydration ratios increased with increasing microwave powers. Chromatic parameters (L*, a*, b*, ΔE) were also influenced by drying temperatures, which contributed to the discoloring of red pepper during the process of drying. [ABSTRACT FROM AUTHOR]
