Falenskaya 4 is a medium-late variety of winter rye, distinguished by high winter hardiness and resistance to unfavorable growing conditions. The variety was developed by the Federal Agrarian Scientific Center of the Northeast named after N.V. Rudnitsky and included in the State Register in 1999 for cultivation in the Northern, Northwestern, Central, and Volga-Vyatka regions. Plants have a height of 102 to 126 cm, an intermediate bush and leaf type with moderate wax bloom. The ear is of medium length, prismatic in shape, loose and semi-drooping, with semi-elongated grain of medium size and a weight of 1000 grains ranging from 26 to 32 grams. The Falenskaya 4 variety demonstrates high yield; the average yield in the Volga-Vyatka region is 36.7 centners per hectare, which is 4.2 centners higher than the standard Kirovskaya 89, with a maximum yield reaching 64 centners per hectare. The vegetative period lasts from 330 to 360 days, corresponding to the medium-late maturity group. Rye tolerates acidic soils with elevated aluminum ion content well, expanding its cultivation possibilities in various soil and climatic conditions. Falenskaya 4 possesses good baking qualities, varying from satisfactory to good. The variety is resistant to grain germination on the root, reducing crop losses. However, it is susceptible to certain diseases: stem and brown rust appear to a medium degree, powdery mildew manifests moderately, and snow mold causes severe damage. Despite this, the variety maintains high winter hardiness and resistance to lodging, making it a reliable choice for agriculturists seeking a stable and high-quality yield of winter rye.
