Due to climate change, high temperatures during sensitive developmental stages of wheat, such as seedling emergence, flowering, and grain filling, have a negative impact on yield. This study aimed to evaluate the response of wheat cultivars to high temperatures through belate sowing and using vernalized seeds, at Isparta University of Applied Sciences, Türkiye. Sowing was carried out on three dates: a winter sowing date (mid-October) and two late sowing dates (April 4 and May 1). Only control seed was used for the winter sowing, while at the late sowing control and vernalized seeds (4 and 8 week) were used. Winter sowing, a common practice in the Mediterranean climate, produced the highest grain yield (mean 5.74 t ha-1). The grain yield was 2.3 t ha-1 for sowing on April 4 and 1.3 t ha-1 for sowing on May 1, resulting in 60% and 77% yield reductions, respectively, for late sowings. Winter (WW) and alternate growth habit wheat (AW) cultivars responded differently to seed vernalization. Spring growth habit (SW) cultivars were not affected by seed vernalization treatments. The adaptability of the landrace cultivars, particularly regarding the sowing dates, was relatively higher. Seed vernalization has the potential to produce economically acceptable grain yields within a shorter growing season, and it can be considered as an alternative wheat cropping practice with appropriate cultivar selection.
