Abstract

As of 2013 130 soybean varieties including eight varieties bred at Kirovogradskaya State Agricultural Experimental Station have been entered in the State Register of plants qualified for growing in Ukraine.

Study aim. Soybean breeding on wide adaptive basis, implementation of the new variety Romashka into industry.

Methods. The main method of variety creation is intraspecies hybridization. The source material is soybean varieties of foreign and national breeding. The variety Romashka was tested in experiments ad modum competitive variety trials in the Kirovogradskiy Institute of Agribusiness in 2004–2009.

Results.  The variety Romashka is mid-ripening (122-129 days), indeterminate; the plant height is 82-98 cm; the height of lower legume attachment is 17-20 cm. The mass of 1,000 seeds is 160-165 g; protein content is 40.0–41.5 %; oil content is 20.0–22.0 %. The variety is resistant to stem rot agents, bacteria, Septorias, variegation agents and common pests. The potential yield capacity is 3.6 t/ha; the yield capacity over the study years was 2.7 t/ha. The variety is intended for grain fodder and food usage. The recommended zones for growing are steppe and forest-steppe. By yield capacity the variety Romashka consistently exceeds the standard varieties by 0.1-0.2 t/ha in different zones.

Conclusions. Implementation of the new variety Romashka into industry will contribute to widening crop areas and increasing soybean productivity in steppe and forest-steppe
