Petropavlivska – a new variety of edible buckwheat, with increased seed productivity and adaptivity in the conditions of the Forest-steppe

Abstract

Actuality. Buckwheat is a valuable food crop with unique medicinal and dietary properties of cereal and the ability to reduce radiation damage, traditional for Ukraine. Despite this, the sown area under buckwheat is insufficient to meet the needs of the population of our country. Under the conditions of climate change, breeders face an acute question regarding the creation of competitive, highly productive varieties of edible buckwheat with increased adaptive potential. Goal. Based on the results of the competitive test of 2018–2020, to select the best high- yielding breeding sample with increased adaptive potential to biotic and abiotic environmental factors in the conditions of the northern part of the Forest-Steppe of Ukraine. Research methods. Field, laboratory, measuring and weighing. Processing the results of experimental studies was performed using Microsoft Excel 2010. Results. According to the results of the competitive test of 2018-2020 selected a breeding sample p-4/13, which over the years of competitive testing significantly exceeded the standard by 95% probability, variety Olha, and proved to be a highly productive population with high adaptive potential. This population in 2020 was transferred to the Ukrainian Institute of Plant Variety Examination for state qualification examination (Application № 20008003 dated 10.11.2020) as a new variety of buckwheat Petropavlivska. Conclusions. A highly productive, early- ripening, determinant variety of edible buckwheat Petropavlivska was created, with biological grain yield of 2.2–2.5 t / ha, weight of 1000 grains of 28.9 g, grain uniformity of 85–88%, grain yield of 72%, protein content of 14,7–15.2%. The variety is resistant to lodging and shedding.
