2023
Alizade, Shader | Mammadova, Ruhangiz
Salinity is one of the serious threats to cotton growth and productivity. The presence of a wide genetic variability of genotypes in germplasm may be an advantage in the creation of salt-resistant varieties in future breeding programs. In this study were analyzed the resistance to salt (NaCl) stress of 48 genotypes belonging to the species G. hirsutum L. and G. barbedense L., as well as chromosome substitution lines. The effect of different concentrations of NaCl on different parameters of 48 cotton genotypes were evaluated and cluster analysis was performed. The correlation between the concentration of salt and the value of different parameters were studied and the lowest germination rate for all genotypes was observed at 200 mM NaCl. There were found a negative correlation between salt concentration and FGP, CVG, GRI, GI and a positive correlation with MGT. According to results of analysos genotypes Navai-9, Karabakh-11, Agdash-3, Flash, AP-317, Kyrgyzstan-174, Karabakh-12, Tashkent-2 and chromosome substitution lines CSB-11, CSB-14, CSB-05, CSB-17 had the highest germination index and showed high resistance to salt stress.
