Abstract
Aim. To study peculiarities of recombination of economically valuable traits in initial sugar beet sources in order to derive from them МS-hybrids with increased yields and tolerance to stressful environments. Results and Discussion. Results of 2015-2022 studies are presented. Temperature and precipitation amount during the growth sugar beet plants were characterized by wide fluctuations in comparison with the long-term averages and influenced the performance. Breeding materials differed in morphological characteristics, biological capacities, qualitative parameters, have various levels of resistance to adverse environmental factors. Under water deficit, new experimental accessions of polyspermous pollinators (PР) - candidates for male components of test hybrids were originated. Valuable sources of performance – female components of monospermous CМS-based hybrids were created. CMS components, which were distinguished as a result of the first cycle of crossings, yielded more roots (56.5 – 58.1 t/hа) than initial forms or the group standard (55.4 t/ha). The sugar content ranged 18.73% to 19.28 % (18.58 % in the standard). Conclusions. At increased air temperature during the sugar beet growth, we selected PР accessions, which gave great yields of seeds and roots. 556-PР4, 558-PР5, 563-PР6, 560-PР7 were the best new pollinators in terms of performance, because they yielded more than the standard (45.3 – 49.6 t/hа vs. 38.4 t/hа, respectively) under water deficit during crucial periods of the growth and development. The sugar content in beetroots was 19.51 – 20.21%, (19.44% in the standard); the sugar collection varied from 9.1 t/ha to 10.0 t/hа (7.4 t/hа in the standard). The following peculiarities were recorded in the selected offspring: increased resistance to droughts and diseases and good storability.
