Abstract:
An in vitro study to select from a number of cayenne varieties possessing resistance to salinity stress derived
from NaCl. The research used Randomized Complete Random (RAL) Factorial with two factors tested,
namely varieties and NaCl salt concentration factor. Varieties of cayenne peppers tested were Tetra Hijau,
Pedas, Cakra Hijau, Sigantung, Wijaya, Sapade, Sret, Bara, Genie and Hanna 08, while the NaCl salt
concentration used on MS medium was 0, 2500, 5000, 7500 and 10,000 ppm. The study was conducted with
four replications. The results showed that the varieties of cayenne pepper, NaCl concentration and
interaction both significantly affected the percentage of normal planlet, plantlet height, root length and leaf
number. In the abnormal percentage of planlet, the treatment of varieties and concentration had a significant
effect, but the interaction of both had no significant effect. Three selected varieties can be used as
populations that can be used in subsequent trials in the f
ield.
