“…In spring bread wheat, a strong, year-independent, direct relationship between yield and plant height was observed (Volkova, 2016). The same pattern has been observed in winter bread wheat, and the range of height in which the maximum yield is formed has been identified (Samofalov et al, 2020;Zakharova et al, 2020). A plant height is also considered as one of the indicators of plant ecological plasticity in various soil and climatic conditions (Ripberger et al, 2015).…”

The genetic control of plant height – important trait associated with yield – is practically not studied in diploid wheats. In this paper, using reciprocal crosses between two Triticum monococcum accessions – var. monococcum (UA0300311) and var. nigricultum (UA0300282) in autumn and spring sowing, inheritance of the plant height is studied. The sowing period significantly affects the expression of einkorn plant height. Data from the generations P1, P2, F1, F2 were used for segregation analysis. For a combination of UA0300311 × UA0300282, the optimal models for plant height inheritance are: at autumn sowing – one main gene with a negative complete dominant effect, its additive effect is –8.05; at spring sowing – one main gene with an additive-dominant effect, its additive effect is –24.51. For the reciprocal combination UA0300282 × UA0300311, at autumn sowing, the optimal model of plant height was one main gene with an equal additive-dominant effect, it additive effect is 10.94; at spring sowing – one main gene with a negative complete dominant effect, its additive effect is –18.37. The heritability was in all cases from 96.52% to 99.70%. The high dispersion of the trait in the second hybrid generation suggests that the studied parental forms differ not only in the main gene, as follows from the results of segregation analysis, but also in the system of modifier genes with a weak effect.

“…According to Zakharova et al (Zakharova et al, 2020), the heritability of plant height is 65.2%, the share of gene-environment component accounts for 30.4% of phenotypic diversity, the environmental one -0.9%.…”

The current study was carried out in the southern part of the Rostov region at the FSBSI “Agricultural Research Center “Donskoy” in 2018–2020. The purpose of the study was to investigate the combined effect of mineral fertilizers and treatments with the growth retardant ‘Moddus’ on productivity of the barley variety ‘Marusya’. In the course of the study, there was identified high responsiveness of the facultative barley variety ‘Marusya’ to the use of mineral fertilizers. Without fertilization, the productivity was 3.46–3.59 t/ha, and 0.87–1.57 t/ha when using the fertilizers. The maximum productivity and protein percentage were established in the variants with the introduction of N79P82K57 according to the active ingredient, with 5.81 t/ha and 0.55 t/ha, respectively. The treatment of plants with the growth retardant ‘Moddus’ contributed to productivity increase on 0.13–0.22 t/ha on average over the years of study. Under the effect of the growth retardant ‘Moddus’, the number of productive heads increased on 5–19 pieces/m2 , there was also a tendency to an increase in the number of grains per head and grain weight per head. The growth retardant ‘Moddus’ contributed to a decrease in plant height on 3.6–5.6 cm, at the same time there was a tendency to increase length of head on 0.2–0.5 cm in comparison with the control variant. Mineral fertilizers effectively increased nature weight of the facultative barley variety ‘Marusya’. Without fertilization, nature weight of grain was 579 g/l and 584 g/l, and when using fertilizers, it increased on 16–27 g/l or 2.7–4.6%. Productivity increase in the variant when treating with the growth retardant ‘Moddus’ resulted in an increase of the indicator of conditional net income over the control variant on 745–1884 rubles/ha.

The current study was carried out in 2019–2021 using the material and technical base of the FSBSI Agricultural Research Center “Donskoy”, in order to research winter bread wheat samples of various ecological and geographical origin according to productivity and some economically valuable traits, to identify the most adapted of them for the conditions of the southern part of the Rostov region. The objects of the study were 17 winter bread wheat samples of ecological variety testing. The variety ‘Ermak’ was used as a standard. As a result of the study, there was found that the productivity of the samples (2019–2021) ranged from 7.75 (‘Etana’) to 9.52 t/ha (‘MV 15-04’). The standard variety ‘Ermak’ (8.20 t/ha) was exceeded by 9 samples ‘Akhmat’, ‘MONE’, ‘KIV – 6’, ‘Astarta’, ‘Slavna’, ‘Chornyava’, ‘XE 9710’, ‘MV 15-04’, ‘No. 71 CIMMYT’, the increase was from 0.45 to 1 .32 t/ha (0.42 t/ha with НСР05). According to ‘heading date’, the samples ‘KIV-6’, ‘Slavna’, ‘Chornyava’, ‘No. 71 CIMMYT’ (May 19–20) belonged to the middle-early maturing group; the samples ‘Akhmat’, ‘MONE’ (May 21–22) belonged to the middle-late maturing group; the samples Astarta, XE 9710, MV 15-04 (May 23–24) belonged to the late maturing group. According to ‘plant height’, the variation ranged from 81.5 cm (‘Akhmat’) to 100.3 cm (‘XE 9710’), the standard ‘Ermak’ had 99.5 cm. All studied samples belonged to a medium-large-grain-sized group (34.05–40.72 g) according to ‘1000-grain weight’. Through the years of study, the sample ‘No. 71 CIMMYT’ showed 0 points of powdery mildew resistance (defeat in the field). There have been identified the best septoria blight resistant samples ‘KIV-6’ (Russia) and ‘Astarta’ (Ukraine), with a damage degree of 5–10 %. The standard variety ‘Ermak’ had 30–40 %. As for yellow rust, the standard variety ‘Ermak’ was damaged on 50–60 %, the sample ‘No. 71 CIMMYT’ was damaged on 20–30 %; the sample ‘MONE’ on 5–10 %; the sample ‘KIV-6’ was damaged on 0–5 %; the remaining samples ‘Astarta’, ‘Slavna’, ‘Chornyava’, ‘XE 9710’ and ‘MV 15-04’ were resistant to this pathogen. According to the complex of economically valuable traits for practical breeding in the conditions of the south of the Rostov region, three winter bread wheat varieties ‘KIV-6’ (Russia), ‘Astarta’, ‘Slavna’ (Ukraine) have been of the greatest interest.
