Determination of Morphological and Physiological Tolerance Levels of Bottle Gourd (Lagenaria Siceraria) Hybrids Obtained by Hybrid Combinations Salt Stress in Hydroponic Conditions

Abstract

Objective: This study was carried out to determine the salt stress tolerance levels of gourd hybrids obtained using advanced lines, which were determined in previous studies to be salt tolerant under hydroponic conditions. Material and Methods: In the study, 4 female parent lines (S7 level), 6 male parent lines (S3 level), 9 hybrid combinations, and 1 commercial bottle gourd rootstock were used as material. Principal component analysis and clustering analyses were applied to determine the salt tolerance levels of the study materials. Results: Members of the cluster that are salt tolerant; While hybrid combinations numbered 8×A13, 9×A11, 6×A12, and 6×A10, those with moderate salt tolerance were plants numbered 9×A1, 1×A13, 8×A16 and A1. Conclusion: Except for hybrids 6×A11 and 9×A16, all other hybrid combinations showed greater tolerance to salt stress than the parental lines and the commercial bottle gourd variety.
