Search for pepper genotypes with high adaptive ability to low night temperatures based on the study of physiological characteristics

This article presents the results of a study on the adaptive properties of various pepper genotypes to low nighttime temperatures (LT) based on their physiological characteristics. It was found that LT slow down growth and reduce yield in most varieties; however, C22 and P08 exhibited resistance to cold stress. The genotypic dependence of plant response is confirmed by the lower sensitivity of varieties C17 and P06. Temperature stress reduced fruit size and contributed to the formation of seedless fruits, whereas in variety C12, the number of seeds increased. The obtained data highlight the importance of selecting resistant genotypes for breeding and successful pepper cultivation under low-temperature conditions.
