Evaluation of salinity resistance and combining ability analysis in the seedlings of mulberry hybrids (Morus alba L.).

ABSTRACT: Soil salinization has become one of the major abiotic stresses influencing food security and maintenance of sustainable eco-environment. Highly salt-tolerant germplasm in mulberry, an important perennial woody plant, could restore the ecology and increase the agricultural income. Studies on the salt tolerance of mulberry are limited. Therefore, the aim of this study was to estimate the genetic variation and develop a reliable and effective evaluation of salt tolerance in 14 F₁ mulberry hybrids that were directionally constructed using nine genotypes, including two females and seven males. A salt stress test was performed using 0.3%, 0.6%, and 0.9% (w/v) NaCl to investigate four morphological indexes of the growth rate: the shoot height (SHR), leaf number (LNR), leaf area (LAR),
