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.

There are many factors responsible for the decline in average wheat yield. One of these determining factors is the sowing date, which greatly affects the grain yield and other quality characteristics. The main objective of this study was to investigate the performance of various wheat genotypes when sown at various dates, including how these sowing dates affected the yield and its components as well as seed quality. Therefore, during the 2018-2019 and 2019-2020 growing seasons, two field experiments were carried out at the Sakha Agricultural Research Station in Egypt using a Randomized Complete Block Design with three replications. There were a total of 30 treatments, including three dates of sowingi.e.5 th November, 5 th December and 5 th January and 10 wheat genotypes i.e.Misr1, Misr2,Misr3, Sakha94, Sakha95, Line1, Giza171, Gemmiza12, Sids14 and Shandaweel1.The results showed that the early sowing date on the 5 th of November gave the highest values for 1000 grain weight, seedling length, dry seedling weight, electrical conductivity, and hectoliter weight. In addition, the December 5 th sowing was placed first and produced the highest number of spikes/m 2 , grain yield and germination %. While, sowing of wheat on 5 th of January, gave the lowest values for all characteristics, except protein % and gluten wet and dry %. In addition, Misr3 cultivar outperformed the other examined genotypes and recorded the highest number of spikes/m 2 and grain yield/fed. The highest values for germination, seedling dry weight, protein content, hectoliter weight, and wet and dry gluten percent were also observed in Line1 genotype. A correlation study of all the assessed characteristics revealed that electrical conductivity test and number of spikes/m 2 were negatively correlated with all the examined quality parameters. It can be concluded that, sowing on 5 th of November is advised for wheat crop to obtain higher yield in five cultivars (Misr3, Sakha94, Gemmiza12, Sids14, and Shandaweel1), but sowing on 5 th of December is advised to maximize wheat productivity and obtain good quality of grains in the other five genotypes. Due to late seeding, Misr3 and Sakha 95, two of the 10 genotypes employed, produced more grain yield than the other genotypes but Line1 genotype was superior for most of grain quality parameters so, this study recommended use Misr 3 & Sakha 95 cultivars and the promissing wheat genotype (Line1) to develop bread wheat genotypes in breeding programs under the environmental conditions of Kafr Elsheikh governorate.

“…In general, late June to mid-July sowing increased plant height of durum wheat. This increment in plant height might be due to the fact that at early sowing crop may have enjoyed better environmental conditions especially soil moisture, temperature and solar radiation which resulted to tallest plants (Bizuwork, 2020).…”

This study was conducted at Setif Agricultural Experimental Station in 2017−2018 crop season, the experimental material used in this study consisted of 5 cultivars (Triticum durum Desf.) based on their difference between early and late cultivation. The genotypes tested were sowing in in a random block design with three replications, each plot consisted of 2 rows of 2.5 m long spaced of 20 cm. The aim of this study is to assess the impact of the choice of sowing date on grain yield, these components as well as some morpho-phenological traits in order to have an idea on the best sowing date. Two-way analysis of variance showed that the effect of sowing date was significant (p<0.001−0.05) with the variables above ground biomass (BIO), spike weight (SW), Thousand kernels weight (TKW), Flag leaf area (LA), plant height (PH), number of days to heading (DH) and canopy temperature (CT), this effect caused the decrease of major parameters studied and mainly grain yield (GY), accompanied by decrease of BIO, SW, TKW, relative Water contents RWC, LA, PH and DH. Ofanto is shown to be the most suitable genotype for the late sowing date (January). The correlation analysis show that GY was significantly, strongly and positively correlated (p<0.001) under both sowing date with BIO and SW. CT was negatively correlated with GY, BIO, SW and HI (p<0.05) who suggest that our plants underwent water stress during the second sowing date.
