Abstract
The results of long-term studies (1955-2022) carried out on typical chernozems of the Tambov region, the northernmost border of sunflower cultivation, are presented. The aim of the research is to create very early and early varieties of sunflower with a growing season of 85-95 days, ripening without the use of desiccants. The effect of moisture availability during the growing season and average air temperature on the productivity potential of various sunflower varieties bred by the Tambov Research Institute of Agriculture - branch of the Federal State Budget Scientific Institution “FSC named after I.V. Michurin" was studied. The negative impact of increased temperature and reduced precipitation on the yield capacity of sunflower varieties has been established. Over the years of research work on sunflower breeding, 19 varieties and 1 sunflower hybrid have been created. Currently, the State Register of Breeding Achievements approved for cultivation in the agricultural production of the Central Chernozem (5) and Middle Volga (7) regions contains 5 varieties: Spartak, Chakinsky 931, Chakinsky 77, PK 05, Chakinsky 100 and one sunflower hybrid Nadezhda, created jointly with OOO “Agroplazma”. In 2021, a new sunflower variety Zagrei 21 was submitted for the State Variety Test.
