Abstract

In Turkey, there is huge diversity in terms of pepper genotypes and varieties. However, in recent years, using standard and hybrid varieties in production caused the reduction of genetic diversity over time. While creating breeding programs for different purposes, the existing gene pool is needed to be well known and it should be enriched according to the breeding targets. In recent years, interspecific hybridization is intensively carried out to increase the existing genetic variation and to extend of genetic bases of varieties that have biotic and abiotic stresses tolerance in pepper breeding programs. The objective of the study was to broaden the existing genetic base by crossing C. annuum (253A and İnan3363) and C. chinense (PI 159236) varieties. The study involves the evaluation of 54 morphological characters. The first three eigen values showed 56% total variance in the F2 population obtained from 253A x PI 159236 crossing (110 offspring), whereas in the F2 population obtained from İnan3363 x PI 159236 crossing (150 offspring), it was 87%.
