Agrobiological characteristics of new buckwheat variety - aleka

Abstract

The main factor to increase and stabilize the buckwheat production in Volga-Vyatka region has been the development and accelerated implementation of early-ripening varieties, which can be adapted to the local soil and climatic conditions. The Nizhny Novgorod Agricultural Research Institute was selecting buckwheat in order to develop varieties combining high crop yields and high grain quality, resistance to lodging and field resistance to phytopathogens. The study was performed in accordance with the public variety testing in 2014-2016. The article presents the results of the study on Aleka (new buckwheat variety), which was developed through a hybrid population [Strelka x Cheremshanka] x Primorskaya 312. A 3-year study revealed that the variety had exceeded Strelka in yields by 0.48 t/ha, in crude protein content - by 0.81%, in resistance to diseases - by 5.7%, in resistance to pests - by 0.9%. In 2016, Aleka was transferred to the public variety testing. Aleka is an adaptive, mid-ripening variety, characterized by high crop yields, (2.38 t/ha), resistance to lodging, high grain quality (crude protein content is up to 14.17%), resistance to diseases, the weight of 1000 gains is 38.2 g. To obtain high crop yields of the variety, it is necessary to take into account the agricultural techniques, including wide-row sowing and direct combining. Due to the lack of seeds, the widerow sowing saves seed material, and the direct combining saves on measures aimed at harvesting the variety.
