Collection, characterization and conservation for sustainability of traditional local pepper genotypes

Traditional peppers (Capsicum annuum L.) are grown in different types and shapes in different local regions in Turkey.
They have significant genetic diversity for processing and consumption.
The development and certified seed production of pepper cultivars from local populations are becoming increasingly necessary.
This study reports on the collection, morphological characterization and conservation of traditional local pepper genotypes.
A total of 50 domestic pepper genotypes were collected from several regions ranging in altitudes from 2 to 1210 m in Turkey.
Morphological characterization of the 50 genotypes was done in the spring season in a greenhouse in Bati Akdeniz Agricultural Research Institute (BATEM). First flowering time ranged from 26 to 41 days, average fruit length ranged from 2.7 to 24.9 cm, average fruit diameter from 15.4 to 103 mm, average fruit thickness from 1.99 to 6.85 mm, average fruit weight from 6.3 to 246 g, average total fruit yield per plot from 2615 to 14,430 g, average total fruit number per plot from 50 to 903, total solids content of water from 3.2 to 5.48% and fruit texture from 6.11 to 13.1 mm s^‑1. Fruit color at immature stage was measured L*, a* and b* values.
A dendrogram was created by using UPGMA with morphologic data.
The genetic similarity rates ranged from 0.31 to 0.96. It is understood that these traditional peppers grown in different regions are important as genetic resources in the development of new cultivars for open fields and protected pepper cultivation.
