Yield stability analysis is important in barley (Hordeum vulgare L.) breeding to produce the highest and most stable yields. This study used parametric and nonparametric statistical methods to assess the barley genotypes' stability. It aimed to assess the 40 barley mutants belonging to the subspecies of two-rowed and six-rowed barley obtained after mutagenic treatment with phosphemide in two concentrations. The study transpired in 2020-2022 in Russia's South Moscow and Tyumen regions. The results revealed that environment (46.6%), genotypes (9.1%), and the interaction of environment by study location (26.2%) and genotype by environment (9.5%) contributed the most to grain yield in barley. The highest correlation appeared among the variables. i.e., Wᵢ² и σ²ᵢ, 𝜃𝜃ᵢ, S²dᵢ; 𝜃𝜃ᵢ и σ²ᵢ, S²dᵢ; NP (4) и S (3) , S (6) ; S (1) и S (2) ; S (2) и S (3) ; KR; NP (2) и NP (3) (r = 0.80-1.00); 𝜃𝜃 (i) и Wᵢ², σ²ᵢ, S²dᵢ; and 𝜃𝜃ᵢ и 𝜃𝜃 (i) ( r = -0.92-1.00). Higher correlation with grain yield emerged with b i (r = 0.52); S (6) (r = -0.77); NP (2) (r = -0.78); NP (3) (r = -0.79); NP (4) (r = -0.78); and KR (r = -0.65). The most stable yields characterized by six-rowed mutants are G20, G22, and G28, derived from the hooded cultivar. The mutants G1, G2, and G40, belonging to the two-rowed barley subspecies, had the highest grain yield potential with less stability.

“…In plants, the first studies to determine mutagen mutagenicity occurred on seeds of Crepis capillaris (L.) Wallr. In addition, studies using this mutagen on winter wheat flax have existed; however, not in barley (Weisfeld, 1965;Bome et al, 2021;Tetyannikov and Bome, 2022).…”

Background. The need to increase the genetic diversity of barley (Hordeum vulgare L.) is determined by its value and cultivation scope, which is especially important in the context of the changing climate.Material and methods. The study was carried out in 2021 and 2022 at the experimental site of the Lake Kuchak biostation located in Nizhnetavdinsky District, Tyumen Province (57°20ʼ57.3”N, 66°03ʼ21.8”E). Mutant forms were obtained by treating seeds of accessions ʻZernogradsky 813ʼ, Dz02-129 and C.I. 10995 with solutions of the chemical mutagen phosphemide at concentrations of 0.002% (2·10–3 М) and 0.01% (1·10–2 М). The mutants of the fifth (M5) and sixth (M6) generations were evaluated for a set of traits valuable for breeding in comparison with the original forms and reference cultivars ʻAchaʼ and ʻAbalakʼ. The main productivity characters were analyzed in the laboratory, and breeding indices were calculated (ear potential index, Canadian index, ear linear density index, Mexican index, plant productivity index, and Finnish-Scandinavian index).Results and conclusion. Most of the studied mutants under moisture deficit and elevated temperature conditions were superior to the original forms in their productivity characters. Mutant plant samples with stable manifestation of those traits, irrespective of the growing season conditions, were selected. Assessment of the genotype–environment interaction using breeding indices made it possible to identify promising mutants for inclusion in breeding programs. Correlation analysis helped to identify indices closely related to grain yield: Canadian index (r = 0.85), Mexican index (r = 0.76), and plant productivity index (r = 0.70). They can be recommended for selection of stress-resistant barley forms.

Yield is an important indicator when creating new varieties of crops. Seeking high and stable yields is considered essential in barley breeding. The stability of the studied genotypes was analyzed using various statistical indicators, namely, bᵢ, S²dᵢ, Wi2, σ2i, CV. The experiment was conducted to evaluate yield and stability of barley mutants of M5-M7 generations by parametric statistics. The experiment involved 40 mutants of spring barley belonging to the two-row subsp. distichon L. and six-row subsp. vulgare obtained after mutagenic treatment with phosphemide in two concentrations. The research was carried out in 2020‒2022 on the experimental plot of Federal Horticultural Center for Breeding, Agrotechnology and Nursery (Moscow region, Russia). Phenotypic manifestation of the considered traits and yield varied depending on the year of the experiment. Mutants G3, G5, G7, G16, G19, G20, G22, G23, G24, G27, G29, G33, G34, G40 were characterized by a statistically signiﬁcant excess of control samples on the weight of 1000 grains. The yield of the studied mutants obtained from the Zernogradsky 813 sample was noted in the range of 282.0– 317.9 g/m2, Dz02-129 had 137.2–201.5 g/m2, C.I.10995 had 90.9–282.7 g/m2, a high variability of this trait was observed with the coeﬃcient of variation equal to 71.02 – 152.42%. The highest value of pair correlation of yield was registered with grain weight per plant (r=0.370) and weight of 1000 grains (r=0.371). Strong conjugation was found between bi and CV (r=0.659); S²di and Wi 2 (r=0.885), σ2i (r=0.885); σ2i and Wi 2 (r=1.000). In addition, a close correlation of yield was noted with bᵢ (r=0.459), S²di (r=0.462), Wi2 (r=0.470), σ2 (r=0.470). Mutants G4, G28, G29 were characterized by relatively stable yields. The complex of economic traits combined with high yield potential was possessed by two-row G1, G2, G40 and multi-row G16, G23 to be recommended for use in the breeding process for high productivity.
