The purpose of the research is to establish the optimal timing of sowing single-seed beet seeds in the Rostov region to obtain queen cells with the manifestation of all varietal characteristics of the root crop. The research was carried out in 2015–2016 in the fields of crop rotation of the Breeding and seed center Rostovsky (Oktyabrsky district of the Rostov region) using field and laboratory experiments, accompanied by accompanying analyses. The soils in the experiments are represented by the Northern Azov variety of ordinary chernozem. The object of research is varieties of single-sprouted canteen beet of various maturation periods: early–ripening variety Khutoryanka (LLC Poisk Agrofirm), medium-ripe – Dvusemyannaya TSKhA (LLC Breeding Station named after N.N. Timofeev), medium-late variety Bordo odnosemyannaya (FSBSI FSVC). Seeds were sown in 5 terms, with a row spacing of 70 cm and with a distance between plants in a row of 6–8 centimeters. Variants of sowing dates: 1 term (May 20–30) – III decade of May; 2 term (June 5–15) – beginning I – end II decade of June (control); 3 term (June 20–30) – III decade of June; 4 term (July 5–15) beginning I – end II decade of July; 5 term (20–30 July) – the third decade of July. The technology of growing root crops was standard for this climatic zone. The sowing scheme is 70×8 cm, the area of the accounting plot is 10 m2. The predecessor is pumpkin crops. During the research, records and observations were carried out in accordance with standard methods. The best results for varieties of all ripeness groups were revealed at the 4 sowing period – July 5–15 (the beginning of the I – end of the II decade of July). In this variant, the highest yield of typical uterine root crops is observed (84–90%) – in the Khutoryanka variety – 257 thousand pcs/ha, Dvusemyannaya TSKhA – 244.82 thousand pcs/ha, Bordo odnosemyannaya 233.8 thousand pcs/ha. At the specified sowing period, the highest indicators of soluble sugars in root crops were noted at 8,6–9,5% and a weak expression of rings on the cross-section.
Key words: table beet, seed production, sowing period, yield of queen cells, root crop diameter, ringiness, standing density, single-growth.
