EVALUATION OF GARDEN RADISH ACCESSIONS FOR PURPOSES OF BREEDING IN WESTERN SIBERIA

Abstract

A number of radish accessions bred home and abroad were examined based on conventional methods for growing vegetables, with the purpose of evaluating parent material for breeding of radish varieties for key economic characters, including productivity, early maturity and yielding capacity. Studies were carried out in Barnaul at the JSC "Industrialny" in 2014 and the West-Siberian Vegetable Experiment Station in 2016. For protected ground were studied Camelot, Corsair and Caiman accessions, sown in February and March, and Carmen and Mercado accessions, sown in spring at two dates. Studies in both experiments were conducted compared to the standard Donar F1. Fourteen accessions sown outdoors were evaluated compared to the standard Krasa Altaya. Observations showed that the radish accessions under study had different responses to lighting intensity during their winter-spring growing period. Under low lighting, Donar and Mercado accessions have demonstrated the fastest rates of commercial root yield formation with compact rosettes of leaves that meet the requirements of radish growing in hydroponic greenhouses. Mercado and Sparkber were remarkable among other accessions for the complex of traits that allowed recommending them to be used as parent material in the further breeding work.
