| description | The current study was carried out on the basis of the Institute of Seed Production and Agrotechnologies, located in the Ryazan Region in 2010–2019, in order to determine the participation share of tillering shoots in the formation of spring wheat productivity in various agro-weather conditions. The objects of the study were the varieties ‘Lada’, ‘Agata’, ‘RIMA’, ‘Maestro’ developed by the Federal Research Agro-Engineering Center VIM. The mean productivity of the studied spring wheat varieties, depending on the level of moisture supply of the growing seasons, had a significant range of 2.20–5.29 t/ha. The mean density of the stems varied from 216 to 620 pcs/m2 among the varieties. The minimum value of 153–253 pcs/m2 was formed under severe drought conditions. When moisture supply improved, the indicator sharply increased in 2.6 times. There has been established that in more humid conditions (HThC 0.98–1.55) the plants were able to realize their potential tillering to a greater extent, the general indicators of tillering among the varieties ranged from 1.06 to 1.23 and 1.63 to 2.11. There was estimated an effect of secondary shoots on productivity, which was 35.2% on average in the trial, and from 10.6% to 48.3% depending on the genotype and environmental conditions. There has been found a shoot formation decrease in 2.4 times of the variety ‘Lada’ under a moisture deficit. There has been determined that the variety ‘RIMA’ had the lowest tillering coefficient for all vegetation periods, and grain weight per a main spike mainly contributed to its productivity. During the moisture deficit periods, the share of the effect of lateral shoots in the variety ‘Agata’ was at the level of mean values, and on 9.9% and 13.1% more than in the varieties ‘Lada’ and ‘RIMA’, respectively. The maximum value of the productivity on the lateral shoots was formed by the variety ‘Maestro’, the productivity share of the secondary shoots during all periods was higher than that of all varieties and amounted to 39.1–48.3%. |
