Abstract A field experiment was carried out in Samawa desert (70 km west of Samawa city, Al-Muthanna governorate), during the 2018-2019 and 2019-2020 agricultural seasons, to study the response of three Iraqi cultivars of wheat (Tamooz2, Ibaa99, Abu Ghraib3) to three planting dates (November 15, 1st December and December 15) under Samawa desert conditions. The results showed the superiority of Tamooz2 cultivar in all traits of the yield components, it gave the highest averages of grain yield, which amounted 5.75 and 5.89 tons/ha−1, weight of 1000 grains, which amounted 29.79 and 31.06 gm, and the number of grains per spike, which amounted 73.02 and 73.76 for the 2019 and 2019-2020 seasons, respectively. The date of December 15th also surpassed in the traits of grain yield, weight of 1000 grains, number of spike grains, and the highest grain yield reached 5.62 and 5.58 tons/ha−1 for the two seasons 2018-2019 and 2019-2020, respectively, and the combination (Tamooz 2 x December 15) gave superiority over the other combinations in terms of grain yield which amounted 6.05 tons ha−1 (2018-2019 season) and Ibaa99 × December 1 gave the highest grian yield about 6.10 tons ha-1 (2019-2020 season).

SUMMARYThe vernalization and photoperiodic response of six locally adapted bread wheat cultivars grown under natural daylength conditions during the summer or winter months was examined in glasshouse experiments. The wheat was vernalized by chilling imbibed grains at 2 ± 1°C for 0, 15 or 45 days. Vernalization for 45 days followed by long summer days led to floral initiation in all cultivars within 28 days but vernalization for 0 or 15 days only led to floral initiation in one cultivar. Vernalization followed by long days reduced the time from transplanting to anthesis, resulting in early ear emergence. Vernalization followed by short days accelerated the development of all the cultivars, but normal development could also occur without vernalization at this time of year. Apical differentiation of the primary shoot and its length and development gave the most reliable information on the period of vernalization required.
