Optimizing sowing date for enhanced heat stress tolerance in canola (<i>Brassica napus</i> L.): Investigating impacts on seed yield, oil content, and fatty acids composition.

ABSTRACT: Environmental conditions, including temperature and the occurrence of phenological stages at the optimum temperature, are effective factors on seed yield, oil content and fatty acids. An experiment was carried out as strip block based on randomized completed block design with three replications in Safiabad Agricultural and Natural Resources Research and Education Center of Dezful during two cropping seasons (2017-2019). Vertical factors consisted of six levels of sowing date (23 Sep, Oct 7, 22 Oct, Nov 6, 21 Nov, Dec 6), and horizontal factors were seven genotypes (Agamx, Hyola4815, Hyola50, Hyola401, Safi6, Zabol9 and Zabol13). Elevated temperatures resulting from postponed sowing dates during the silique formation and seed filling phases led to a decline in seed yield, oil content, and m
