Abstract

Capsicum sp. Has been reported as a salt-sensitive crop. Therefore, using salt-tolerant varieties will be a wise solution for maintaining crop production in coastal areas. Source of saline-tolerance controlling genes are needed to develop saline-tolerant genotypes. The objective of this study was to evaluate the tolerance of cayenne accessions to salinity stress during the vegetative phase based on the leaf damage symptoms. The experiment was carried out using a hydroponic technique with a solution of macro and micronutrients AB mix supplemented by 6000 ppm NaCl. A total of 20 genotypes of cayenne pepper were evaluated in a completely randomized design with three replications. Each experimental unit consisted of two plants grown in polybags with sand media. To determine the tolerance level of plants to salinity stress, the tolerance index (TI) was calculated based on the score of leaf symptoms. The results showed that genotypes A21 and A32 exhibited better vegetative growth performance in leaf greenness, number of leaves, and stem diameter compared to other genotypes. There was no saline-tolerant genotype found. All genotypes showed abnormal symptoms on the leaves. However, the sensitivity index indicated that genotypes A21 and A32 were classified as moderately tolerant with the mildest symptoms.
