“…These results revealed that selection plants for these traits should be postponed to the later generations because of predominance of non-additive gene action for all studied traits. These consequences are in arrangement with those of Fellahi et al (2013), Abd El-Aty et al (2016), Ali (2019), El-Gammaal (2019, Dhoot et al (2020), Roy et al (2021b) and Chaudhary et al (2022).…”

“…In the early stages of a breeding program, plant breeders need general knowledge about gene action and the genetic system that governs traits. Plant breeders always seek to search for the best genotypes with a high general combining ability so that they can cross between them to be able to get the best hybrids with specific combining ability, and therefore these hybrids can be used to conduct selection in the segregating generations to obtain superior genetic segregants (Rajput & Kandalkar, 2018;Chaudhary et al, 2022). The combining ability gives important information regarding the selection of parents on the basis of their performance in their crosses, and also helps breeders to determine the best parents that are crossed together to exploit the heterosis Egypt.…”

The two lines, Sids 14 (L3) and Misr 2 (L5) were a good donner for biological yield/plant BY/P in g, no. spikes/plant NS/P and grain yield/plant GY/P in g. Significant positive general combining ability effects estimated for NS/P, GY/P, weight of grains per spike WG/S in g and 1000 grains weight 1000GW in g for line 4 (Misr 1) and line 5 (Misr 2). Sids 12 (T1) was a good donner for BY/P, NS/P, GY/P and 1000GW. Cross L4 × T2 showed significant negative (desirable) specific combining ability for days to heading. Four crosses, L2 × T3, L3 × T1, L3 × T2 and L4 × T1 exhibited significant positive specific combining ability effects for grain yield/plant. For days to heading, cross L3 × T2 showed significant negative heterosis relative to mid-parents and better parent. Six crosses, L3 × T1, L3 × T2, L4 × T1, L4 × T3, L5 × T1 and L5 × T3 showed significant positive heterosis for grain yield/plant over the mid-parents.

Water stress conditions have occurred in the past in various places of the world, affecting the yield and production of numerous crops, including wheat. The aim of this research was to estimate standard heterosis under two different water regimes for grain yield and its attributes in 33 crosses, which were obtained by crossing 11 lines and 3 testers in a Line × Tester mating design. The best cross combinations for yield and contributing traits under irrigated condition were C4, C8, C33, C24, and C23, compared to both checks HD2967 and PBW660. Whereas, in rainfed condition, C18, C14, C26, C21, and C20 crosses were superior to the checks. For both irrigated and rainfed conditions, the best cross combinations identified were C29, C15, C32, C2, and C31. As a result, these cross combinations could be used in wheat breeding programmes to improve bread wheat genotypes for increased grain yield, agro-morphological features, and water stress tolerance. The presence of high heterosis for yield-contributing traits not only aids in the development of hybrids by exploiting heterosis but also in the production of transgressive segregants to develop elite lines.

Wheat grain has a unique nutritional value and contains health-promoting and essential components in the daily human diet. Increasing consumer awareness of health and nutrition has led to a greater focus on sustainable and healthy wheat production in the face of climate change. The aim of this study was to determine the effect of nitrogen on yield and protein characteristics as well as antioxidant capacity and essential amino acid profile of bread wheat genotypes adapted to different ecological conditions. Different nitrogen doses (0, 60, 120 and 180 kg ha-1) were applied to 15 genotypes (3 lines, 1 hybrid and cultivars) with different growth habit to determine yield, quality, antioxidant and amino acid composition parameters. As a result of this study, total phenol content, antioxidant activity and gluten index of wheat decreased although grain yield potential increased in genotypes. In the results where the genetic factor is the primary focus, it was established that the responses to nitrogen fertilizer doses exhibited variability across different years particularly the case during the dry season. With regard to the YearxNitrogenxGenotype interaction, a notable increase was observed in total phenol content and antioxidant activity, while a decline was evident in yield, protein, and wet gluten parameters, particularly in the nitrogen dose applied during the dry season. The increase in protein content contributed significantly and positively to the essential amino acid composition. However, increasing the amount of some amino acids negatively affects others. The objective of this study is to identify and contribute insights into the impact of nitrogen factor on product quality, health and nutrition issues, grain yield potential of genotypes, plant breeding and agronomic studies.
