Chulpan 9 is a late-maturing variety of winter rye, developed to achieve high yield and ensure good grain quality. It was created based on complex hybridization involving the Chulpan, Chulpan 3, Otello, Kustro, Imeryg 1, 2, 3, and other varieties, with multiple individual and individual-seed selections. The plants have an intermediate bush and leaf type, which are pubescent and covered with a strong waxy coating. The ear is mainly spindle-shaped, medium, loose and erect, with semi-pressed, medium-length, tender and elastic yellow awns. The grain is elongated and elongated-oval, of medium size and semi-open, with 1000 grain mass varying from 24 to 39 grams depending on the region. The variety is distinguished by high winter hardiness and lodging resistance at or above the standard level. The vegetation period is from 314 to 334 days, corresponding to late-maturing varieties. Plant height is in the range of 87-95 cm, which is slightly below the standard. Chulpan 9 has good baking qualities, making it attractive for agricultural production. Disease resistance varies: the variety is moderately resistant to stem rust, susceptible to brown rust, moderately susceptible to powdery mildew and highly susceptible to snow mold. The variety is recommended for cultivation in the Volga-Vyatka, Ural and West Siberian regions, where it shows stable results. Average yield in the Ural region is about 22.7 c/ha, in the Volga-Vyatka region — 41.7 c/ha, and maximum yield reached 64.1 c/ha in Bashkortostan, where the record was 70.0 c/ha. Chulpan 9 is well suited for crop rotation and provides stable care for crops, making it a profitable choice for farmers seeking high quality and crop quantity.
