“…Among the yield attributing traits, the PCV values were, in general, greater than the GCV, which reflects the influence of the environment in the expression of these evaluated characteristics. These findings were in agreement with those of Din et al (2018) and Regmi et al (2021).…”

“…GAM was found just intermediate in the FLA (15.22) and low in the remaining traits. The obtained results are consistent with those of Seyoum and Sisay (2021) for PH, Hossain et al (2021) for CT, Fellahi et al (2019) for heading date and FLA, Din et al (2018) for TKW, and Regmi et al (2021) for the number of fertile tillers and GY.…”

The genetic improvement of any breeding population largely depends upon the magnitude of genetic variability present. This study was carried out to estimate parameters of the genetic variation among 13 quantitative traits of bread wheat evaluated at INRAA-Setif institute (Algeria) during the 2020–2021 crop season in a rainfed environment. 34 genotypes including four control checks were planted in a randomized complete block design with three replications. Genotypes showed significant variations for almost all the studied traits. Proline content, spikes weight, and grain yield exhibited a high genotypic coefficient of variation along with moderate to high heritability coupled with a high genetic gain, suggesting the implication of additive gene action. The number of spikes, spikes weight, and thousand kernel weight were significantly and positively correlated with grain yield at both phenotypic and genotypic levels. Path analysis results showed that spikes weight is an important route through which most of the measured traits influenced indirectly grain yield. Lines L1, L20, L28, L16, and L18 exhibited a sizeable grain yield advantage, which suggests they are potential candidates for future release and could be incorporated into the wheat breeding programs as parents to improve yield in the rainfed environments of Algeria

W heat is a self-pollinating annual crop which belongs to grass family Gramineae and one of the most growing cereal crops globally. Wheat delivers food to 36% of the worldwide inhabitants and subsidizes 20% of food calories. Wheat is grinded to flour which is the key product of wheat used for making different food items like roti, pastry, cakes, chapattis, and wafers, whereas straw is used for feeding animals. The total protein found in wheat is about 75%, among which gluten is one of the key proteins found in grains of wheat. Due to it wider adaptability and products derived from wheat grains, wheat is cultivated across forty-four nations worldwide (Kumar et al., 2017).

Bread wheat germplasm has wide genetic diversity, which means it can withstand a lot of biotic and abiotic stresses. Despite the presence of bread wheat germplasm diversity in Ethiopia, wheat production in the Kafa Zone is significantly lower than the national average. The ultimate goal of this research was to determine the genetic diversity of grain yield and yield components of bread wheat. One hundred bread wheat accessions with 3 local checks were evaluated in augmented randomized complete block design at Kafa Zone, Gewata Woreda Shupa site, during the 2018–19 growing season. The mean performance of the accessions revealed that accession number 29812 yielded more grain than the others. Spike length, number of seeds per spike, biomass yield, and harvest index all had moderate genotypic coefficients of variation. Spike length, number of seeds per spike, thousand seed weight, biomass yield, and harvest index all had moderate-to-high heritability and also all the above-listed traits had moderate-to-high genetic advance as a percentage of the mean. This means that practical improvement of these essential traits can be achieved by effective and satisfactory selection. Grain yield has positive correlations with grain filling period, number of productive tillers, spike length, number of seeds per spike, thousand seed weight, and biomass yield. The principal component analysis grouped all of the traits into four main components. Seven clusters and one ungrouped accession were formed from the accessions. Cluster IV and cluster VI had the greatest intercluster distance (D2 = 104.77) among the clustered groups, suggesting the probability of selecting a parental genotype for hybridization. However, the current result is merely indicative and cannot be used to draw firm conclusions. As a result, the experiment should be replicated in different locations and seasons for greater consistency.
