To improve agronomic and quality in bread wheat, this experiment was performed in 2015/16 and 2016/17 seasons at Sakha Agricultural Research Station, Egypt to study performance of ten bread wheat (Triticum aestivum L.) genotypes (Giza 171, Sakha 95, Gemmeiza 12, Shandweel 1, Sids 12, Sids 14, Misr 3, Line 1, Line 2 and Line 3) and their forty-five F 1 crosses were evaluated for sixteen agronomic and grain quality characters. The mean squares for genotypes, parents, crosses, parents vs. crosses, general and specific combining ability were significant for most studied characters. The ratio of general and specific combining ability was more than unity for all characters and both additive and non-additive gene effects were important in controlling the studied characters with more importance for additive effects. The best performance was detected in Sakha 95, Sids 14 and Shandweel 1 for grain yield plant -1 , all parents except for Sids 12 and Giza 171 and Shandweel 1 for yellow rust, Line 1 for stem rust and Gemmeiza 12 and Sids 12 for dry gluten. The best combiners were Sakha 95, Sids 14, Giza 171 and Misr 3 for grain yield plant -1 and Giza 171, Sakha 95, Gemmeiza 12 and Shandweel 1 for wet and dry gluten. Grain yield plant -1 had positive significant correlation with grain filling rate, plant height, number of spikes plant -1 and kernel weight. The correlation of dry gluten was significant and positive with wet gluten and negative with hydration capacity percentage. Path coefficient analysis showed that the highest positive direct effect on grain yield plant -1 was obtained by grain filling period, wet gluten, days to maturity and days to heading. On the other hand, the highest negative direct effect was detected by dry gluten, hydration capacity percentage and days to anthesis. The highest positive direct effect on dry gluten was obtained by wet gluten, grain filling rate and days to maturity. Meanwhile, the highest negative direct effect on dry gluten was obtained by grain yield plant -1 , hydration capacity percentage and days to anthesis. Using stepwise regression, days to heading, grain filling period and rate, kernel weight, yellow rust resistance and electrical conductivity had justified the maximum of grain yield plant -1 changes. Number of kernels spike -1 , wet gluten and hydration capacity percentage had justified the maximum of dry gluten changes. Giza 171 × Misr 3, Line 1 × Line 3, Sids 12 × Misr 3, Giza 171 × Line 2, Sakha 95 × Shandweel 1, Sakha 95 × Gemmeiza 12 and Shandweel 1 × Misr 3 crosses had high yield potentiality and resistance to yellow rust and moderately susceptible to stem rust, consequently these crosses will be favorable in wheat breeding programs. Sakha 95 × Gemmeiza 12 and Sids 12 × Misr 3 were the best crosses for dry gluten and will be promising in breeding for wheat grain quality.

Six wheat varieties were single crossed at 2017/18. Six parents and its 15 F1 single-crosses were cultivated under N-normal and N-stress at 2018/19, to study heterosis and the genetic parameters for yield and its components under normal and N-stress. Mean squares of wheat-gentypes, parent, F1-crosses and parent versus cross were highly significant or significant for most of traits under both conditions. The highest desirable heterosis and heterobeltiosis were detected by crosses No. 7 and No.8 for earliness; No.14, No.8 and No.3 for 100-Grain weight; crosses No.8 and No.13 for number of spikelets/spike; crosses No.9, No.7 and No.13 for number of grains per spike; cross No.4 for number of spikes/plant; crosses No.3, No.12 and No.10 for grain yield per plant, therefore, it might be decided that these crosses may be beneficial for enhancing wheat grain-yield programs under low or high N conditions. The median grade of dominance was greater than one for all characters under both conditions, suggesting the importance of over dominance gene effects in the genetics of these traits. Heritability in broad sense (hb.s.) had high values for all traits under both conditions. Lower heritability estimates in narrow sense (h 2 n.s.) were detected for all the studied traits under both conditions, except each of spikes number /plant, weight of 100-grain and protein % at both conditions which had moderate values of narrow sense heritability, reflecting the part of environmental factors and dominance genes in heirloom scheme of these characters.

Genotypic variation and stability for nitrogen use efficiency in winter wheat

et al. 2020

Wheat (Triticum aestivum L.) products account for a large portion of the total dietary calories and protein consumed globally, thus requiring efficient N management systems for optimal grower profitability and to reduce negative environmental impacts of nontarget fertilization. This investigation sought to evaluate genotypic variation for N use efficiency (NUE), assess yield stability, and validate traits for improvement of crop performance across N rates. Three separate studies were conducted over four growing seasons in the eastern United States that varied in the number of N rates and site‐seasons. Study I was conducted using five N rates over three site‐seasons, Study II was conducted using three N rates over six site‐seasons, and Study III was conducted using two N rates over nine site‐seasons. Genotype × N rate interactions were more frequently observed for grain yield when three or more N rates were used in the experimental design. The three studies identified significant genotypic variation for NUE and identified wheat lines that consistently expressed high grain yields over N‐site‐seasons. Aboveground biomass at physiological maturity was strongly associated with grain yield in Study II when 67 kg N ha−1 (r = .66, P ≤ .05) was applied and in Study III when 67 kg N ha−1 (r = .71, P ≤ .05), and 134 kg N ha−1 (r = .89, P < .001) was applied. Findings from this investigation inform soft red winter wheat breeders on diverse sources of breeding materials and target traits to improve NUE.
