“…Among the wheat traits, grain yield is one of the most important and complex polygenic trait, influenced by many components. Since that favorable combination of yield components may improved grain yield, analyzing various traits related to grain yield, as well as the selection of genetically suitable parents in crosses are the initial breeding steps which could ensure success in breeding programs (Ilker et al, 2009). Keeping this in view, wheat breeders have been concentrated on development of high yielding wheat cultivars by crossing good general combining parental lines and selecting desirable transgressive segregants from resulting hybrids for grain yield traits (Istipliler et al, 2015;Kumar et al, 2015a).…”

One of the most important tasks in wheat breeding program is development of high yielding wheat cultivars by crossing the lines with good general combining ability (GCA) and selecting desirable genotypes within its segregating population for grain yield traits. The objective of this study was to estimate the combining ability and gene action involved in the expression of the traits grain weight per spike and grain weight per plant of wheat in F 1 generations, in 5 × 5 half diallel cross of bread wheat varieties (Triticum aestivum L.). The results of applying combining ability analysis indicated that among the parents, genotypes Sara, Pobeda and Renesansa were found to be the best general combiners for the both investigated traits. The best specific crosses for both traits were Sara/Partizanka, Pobeda/Sara, Renesansa/Partizanka, Partizanka/Pesma and Pobeda/Pesma. Most of the specific crosses involved high × high, high × low and low × low general combiners. The results of regression analysis, as well as the analyses of components of genetic variation indicated overdominance in the inheritance of examined traits suggested that selection in later segregating generations may lead to fairly good improvement in these characters.

“…Genetic studies confirmed that cultivar 'Amigo', has Pm17 and leaf rust resistance gene Lr24 on a translocated chromosome involving 1 A and 1B, respectively (Hsam and Zeller, 2006), the Pm8/ Pm1 alleles at the locus (Mohler et al, 2008) and Amigo is a source of Sr24/Lr24 (The et al,1991). There are many explanations for the number of genes that conditioned resistance to powdery mildew in wheat (Peusha et al, 2002, Srnic, 2003Ilker et al, 2009). Adult plant resistance (APR) to cereal fungal diseases provide protection in a crop's post-seedling stages typically between tillering and booting according to Adult Plant Resistance Fact Sheets GRDC, Nov. (2012).…”

Eight F 2 populations of crosses carried out between the resistant cultivar Amigo and 8 susceptible bread wheat cultivars were evaluated to study the inheritance of resistance to powdery mildew (Pm) caused by Blumeria. graminis f.sp. tritici and also to estimate the number and action of genes related to adult plant resistance. The response to powdery mildew disease was studied in a conditioned glass house and natural infection in the open field. Individual plants were scored and classified as resistant or susceptible according to a specific scale. The tested local wheat cultivars showed susceptible responses at both seedling and adult stages, while the Amigo cultivar was susceptible at seedling stage and resistant at adult stage. The F2 plants of all tested crosses were susceptible at seedling stage and resistant at the adult stage. Obtained results revealed that the inheritance of resistance is ruled by a single gene in the crosses Amigo/Sids12 and Amigo/Misr2; and by two recessive genes in Amigo/Gemmeiza 11 cross. The inheritance of resistance in F2 populations of Amigo/Sakha 95, and Amigo/Giza 171 crosses is controlled by two dominant genes, while in Amigo/Gemmeiza 12, Amigo/Sakha 94 and Amigo/Misr1 crosses is conditioned by two incompatible dominant genes. Sakha 95 and Giza 171 wheat cultivars were the best and suitable for transferring the adult plant resistance gene Pm17.

“…However, the grain yield of wheat, along with spike architecture, is a very complex and polygenic trait influenced by many yield components (Reynolds et al ., 2009;Kumar et al ., 2022) . A favourable combination of yield components may improve grain yield, but the increment in one component might have a positive or negative effect on the other components (Ilker et al ., 2009;Ljubičić et al ., 2017) . Cereals possess a degree of developmental plasticity that allows for increases in kernels spike -1 or kernel weight to compensate for losses in tiller number .…”

Bread wheat is one of the most important crops in the world. Wheat breeding has been based on science and has been constantly evolving due to breeding program improvements. Improving yield potential, resistance/tolerance to biotic and abiotic stresses, and baking quality are priorities for breeding this cereal. Soil and climatic conditions are one of the most important factors affecting the grain yield of wheat. During the two vegetation seasons, phenotypic variability and genotype by environment interaction (GEI) for spike index of eleven wheat genotypes were studied under specific growing conditions of halomorphic soil, solonetz type. The combined ANOVA showed that the phenotypic expression of spike index was significantly influenced by environmental variations, because the significant variance explained 48.8 % of the total variation, while genotype contributed with 7.8 % of the total variation of the experiment. The first source of variation IPCA1 explained 55.6 % of the GEI variation for the spike index of wheat. Genetics analysis of different wheat genotypes grown in different agro-ecological conditions contributes to their better utilization, as well as, selection for crosses in wheat breeding programs.
