Nine bread wheat early maturing promising lines and three local cultivars were evaluated at Mallawy Agric. Res. Stations, ARC, Egypt, for the two successive growing seasons of 2018/2019 and 2019/2020 under the two sowing dates, the recommended (SD1:30 th November) and the late sowing date (SD2:30 th December). A split-plot arrangement with three replicates was used in each season. The aim of this study was to select the best genotypes for early maturity and higher grain yield. The results showed significant differences among genotypes for all studied traits in the optimum sowing date (SD1) compared to late sowing date (SD2). The optimum sowing date (S1) produced the highest values for all studied traits in both seasons, while the late sowing date (S2) was recorded the earlier plants for heading and maturity dates. The studied genotypes differences significantly in all estimated traits, lines 1 and 2 had the earliest genotypes for heading days, while Giza 171 and line 8 were the latest one for this trait. On the other hand, lines 9 and 4 were the earliest genotypes for maturity date, while the latest one was recorded for Giza 171. Line 5 surpassed all the other genotypes in grain yield (28.31 and 23.17 ard. fed -1 ) in the first and second seasons, respectively and it is appeared to be more tolerant to late sowing date as well as heat stress. The interaction (SD x G) had a significant effect on most studied traits. Lines 9 and 6 were the earliest genotypes for maturity when sown on 30 Nov. also, lines 9 and 4 were the earliest genotypes when sown on 30 Dec. The highest grain yield was obtained from line 4 followed by line 5 when sown on 30 Nov. and line 5 had the highest grain yield when sown on 30 Dec. in the first season. While, in the second season, lines 5 and 8 recorded the highest grain yield when sown on 30 Nov. and 30 Dec. respectively. Line 5 is suitable for planting in a wide range of planting dates (from 30 th Nov. to 30 th Dec.). Moreover, it is early maturing and can be recommended for late sowing (30 th Dec.). Therefore, the results of the present study confirmed that lines 4, 5, 7 and 6 were superior over the other genotypes in producing the earliest maturity date and higher grain yield and can be used, in future, in bread wheat breeding programs for the development of wheat cultivars for high temperature stress condition at the terminal growth stage.

“…Choosing the right sowing dates can maximize the outcomes of the interaction between genotype and environment, thus increasing grain yield and baking quality of wheat (Silva et al, 2014). Sowing of wheat during November gave the highest values for each of the yield and its components, while the late sowing in early or mid-December led to a decrease these values and an increase in the grain content of protein (El-Hag Dalia, 2019;El-Sayed et al, 2018;Farooq et al, 2016;Taha et al, 2017).…”

Two field experiments were conducted in El-Monera village, the New Valley governorate, Egypt, during the two successive winter seasons of 2017-2018 and 2018-2019, to study the effect of three sowing dates i.e., (1 st November (D1), 15 th November (D2) and 1 st December (D3)) and foliar spray with antioxidants (Ascorbic acid, citric acid and ascorbic + citric acids at 200 ppm and tap water as control) on two bread wheat cultivars (Sids12 and Misr1) under New Valley governorate conditions. The experimental design was a randomized complete block design (RCBD) in spilt-split plots with three replications. The obtained results pointed to sowing date, antioxidants treatments and wheat cultivars had highly significant effect (prob ˂0.01) on all studied traits in both seasons. The highest values of total chlorophyll content, flag leaf area, plant height, number of grain /spike, 1000-grain weight and number of spikes /m 2 as well as grain and straw yields ton /feddan (feddan = 4200 m² = 0.420 hectares = 1.037 acres) were recorded when wheat was sown at 15 th November. On the other hand, the highest percent of protein in grain were recorded at1 st December. Ascorbic + citric acids at 200 ppm foliar spray treatment gave the highest values of all studied traits. Also, Misr-1 cultivar was superior to Sids-12 in all traits under study. The first and second order interactions exerted significant effects on all most traits under study. In general, the highest grain and straw yields were obtained from Misr-1 cultivar when was sown at15 th November and was sprayed with mix of ascorbic/citric acids at 200 ppm.
