Three decades ago, breeders working with meadow clover in various soil and climatic zones of Russia and Belarus decided to join their efforts. How viable was this idea? What results did she give?

What is CBT?

Meadow clover (Trifolium pratense L.) is one of the most productive perennial legumes. It is necessary for the production of high-protein bulk feeds and the biologization of agriculture in various areas of the European forest and forest-steppe territory, in the taiga and sub-taiga zones of Siberia, as well as in the Far East and other regions of Russia. Due to the geographical and ecological diversity of these zones, early ripe varieties with high plasticity and resistance to stress factors are relevant, which can form a crop before the onset of stressful effects of the habitat or compensate for it due to mowing.

The variety of soil and climatic conditions of the zone of clovering should be taken into account when building a breeding program with clover based on the principles of ecological selection.

The main tasks of selection of meadow clover are to improve its ability to tolerate cold and winter frosts, grow on acidified soils, increase resistance to drought, soil waterlogging, pathogens and phytocenotic environment, early maturity.

To solve these problems and in order to increase the effectiveness of clover breeding in Russia and Belarus under the leadership of the All-Russian Research Institute of Feed in 1986, a creative association of breeders “Clover” was created on a voluntary basis. It includes 15 scientific institutions of Russia and Belarus, located in 7 soil-climatic zones of Russia:

– All-Russian Research Institute of Feed named after V.R. Williams

– NIISH of the North-East named after N.V. Rudnitsky

– Siberian Research Institute of Feed-

– Research Institute of Mining and Piedmont Agriculture –

– VNII grain and cereal crops-

– NIISH North-West-

– Smolensky NIISH –

– NIISH of Northern Trans-Urals –

– Tula NIISH –

– Falensky selection station –

– Kotlas SOS-

– Voronezh experimental station for perennial herbs –

– Kostroma State Agricultural Academy-

– Belarusian State Agricultural Academy-
