Abstract

Saline tolerant genotypes are required in the development of saline adaptive cayenne cultivars. Salinity tolerance was reported to be polygenic controlled. Evaluation of saline-tolerant genotypes involving many characters simultaneously might increase the success of selection. This study aimed at evaluating the tolerance of cayenne pepper accessions to salinity stress employing the stress tolerance index (STI). A total of 20 genotypes were grown using a wick-system hydroponic. Each polybags containing dirt-free sand media were placed on a plastic container containing AB mix nutrients. The media was connected to the nutrient solution by a wick of flannel fabric. NaCl stressing media was prepared by fortifying the AB mix nutrient with 6000 ppm NaCl. A control media was also prepared without supplementing NaCl into the AB mix nutrients as a comparison in evaluating the decrease in growth and yield. The experiment was carried out in a greenhouse with a completely randomized design with three replications. Each experimental unit consisted of two plants. To determine the level of plant tolerance to salinity stress, STI value was calculated which involved 13 cayenne growth and yield variables. The results showed that the tolerant genotypes based on average STI were A25_Bogor2, A26_Magelang and A29_Bengkulu8. Genotypes that were moderately tolerant were A02_Bengkulu2, A07_Bangka, A11_Temanggung1, A13_Bengkulu3, A16_Bengkulu4, and A32_Bengkulu10. The remaining 10 other genotypes are classified as sensitive.
