Keragaan Agronomi Cabai Keriting (Capsicum annuum L.) IPB di Lahan Pasang Surut Sumatera Selatan
The use of curly chili as a food ingredient continues to increase. It is necessary to increase production through the use of superior varieties by utilizing tidal land that is widely available in South Sumatra. This research aimed to obtain superior varieties of curly chili IPB with the potential to be developed for tidal land of South Sumatra. The experiment was conducted from July 2020 to January 2021 on potential acidic sulfate soil of tidal land overflow type C, using a randomized complete block design with three replications. Tested genotypes were six IPB’s curly chilies, namely F10-120005-141-16-35-3-2B, F10-120005-141-16-35-1-4-3B, F10-120005-141-16-35-7-1-3B, F10-120005-241-2-9-4-4-1-1B, F10-120005-120-7-1-7-8-1-2B, F11-0005-9-6, and four check genotypes, namely SSP, Laris, Caman, F1-PM999. Analysis of variance followed by the HSD test was conducted. The relationship between variables was analyzed using Pearson correlation. Test genotype F10-120005-120-7-1-7-8-1-2B had tall stems and produced higher fruit weight than the check genotype, as it has the highest flesh thickness, longer fruit, and the largest fruit diameter. IPB genotypes F10-120005-141-16-35-1-4-3B, F10-120005-141-16-35-7-1-3B, F10-120005-241-2-9-4-4-1-1B, F10-120005-120-7-1-7-8-1-2B are potential to be developed as superior curly chili varieties in potential acidic sulfate soil on tidal land of South Sumatra, with productivity ranging from 11.38 to 12.92 ton ha-1. Curly chili genotype had different growth abilities in tidal land depending on their ability to adapt to the growing environment according to their genetic characteristics.
