Abstract

To develop high-yielding and salt-tolerant mutant lines of oilseed rape, the cultivars RGS003 and Sarigol were treated with different doses of gamma radiation (700, 800, and 900 Gy). Selection and management of segregating generations up to the fifth generation (M5) were carried out using the pedigree method under saline soil conditions at the Gorgan Salinity Research Station. Among the 148 selected mutant lines, 100 lines with high oil content were chosen. Following a three-year evaluation under saline soil conditions in Gorgan, line SRL-93-8 derived from RGS003 and treated with 700 Gy, was identified as a promising line and selected for evaluation in preliminary yield trials. In yield trials conducted in Gorgan and Sari, line SRL-93-8 achieved a grain yield of 2,930 kgha-1, showing a 22.7% superiority over the control cultivar RGS003, which yielded 2,386 kgha-1. In the adaptability trial, the line also outperformed the control, with an average yield of 2,509 kgha-1 compared to 2,155 kg/ha. On-farm research-extension trials further confirmed the superiority of this line under farmers' conditions. Given the favorable characteristics of SRL-93-8 compared to the control such as salt tolerance (EC = 8–16 dSm-1), higher grain yield (+449 kg), higher 1,000-seed weight (+0.36 g), more siliques per plant (+26), higher oleic acid content (+2.13%), and lower levels of linoleic acid (–1.4%) and linolenic acid (–1.39%) as well as its 28.11% higher oil yield, high stability, and uniform maturity, this line was officially named Roshana in 2020 and recommended for cultivation in the south warm regions of the country.
