Winter bread wheat Triticum aestivum L.
An intensive cultivar with short stems

Harmonika was included in the State Register of Plant Varieties Suitable for Dissemination in Ukraine in 2017 for growing in the forest-steppe and steppe.

Variety - erythrospermum.

This cultivar has short stems, is resistant to lodging and major diseases. Frost tolerance is increased (7.5 points). The grain quality meets the requirements for valuable wheat.

Harmonika gives stable high yields. The 1000-grain weight is 42.7 g. In 2020 in the competitive variety trial at the PPI named after VYa Yuriev the average yield was 7.98 t/ha, in the experiments of the Laboratory of Plant Production and Variety Investigations it was 6.78 t/ha. The average yield was 6.71 t/ha in the demonstration fields of the SE Experimental Farm Krasnohradske and 8.87 t/ha in the demonstration fields of the Institute of Agriculture of the Northeast of NAAS.

This cultivar is intensive; the best predecessor is black fallow with optimal doses of mineral fertilizers. To give high grain yields, Harmonika requires protection against pests and diseases. Prior to sowing seeds should be treated with a fungicide-insecticide mixture. The seeding rate is 4.5 million germinable seeds per 1 hectare after fallow and 5.5 million seeds after non-fallow forecrops. Its grain is well-filled, but not large, which should be taken into account when chaff is separated from grain.
