Winter wheat BUNCHUK

Originator: Breeding and Genetic Institute — National Center for Seed Breeding and Variety Studies of the National Academy of Sciences

In the Register of Plant Varieties of Ukraine since 2009, recommended for sowing in steppe and forest-steppe zones.

Economic and biological characteristics:

A variety of high-intensity steppe ecotype, suitable for growing in different agrobackgrounds. The yield of 72.3-89.4 t/ha during the years of competitive variety testing at the institute was formed due to high productive bushiness (from 620 to 820 stems per 1 m2) and high grain size (up to 55-65 grains in an ear). Bunchuk exceeds the productivity of the standard variety by 5.7-11.7%.

● Belongs to the group of mid-early, with the duration of the vegetation period 278-283 days.
