The article presents the results of field germination studies of ultra-early winter wheat varieties Flesh, Ultra, and Chillaki during 2024–2025. The results showed that Flesh and Ultra varieties had higher field germination rates than the control variety in both years. The highest values were recorded for the Flesh variety, indicating its potential for cultivation.

В статье представлены результаты изучения полевой всхожести ультраскороспелых сортов озимой пшеницы Ультра, Флеш и Чиллаки в 2024–2025 годах. Установлено, что сорта Ультра и Флеш в оба года исследований обеспечили более высокую полевую всхожесть по сравнению с контрольным сортом. Наилучшие показатели отмечены у сорта Флеш, что свидетельствует о его перспективности для возделывания.

Maqolada 2024–2025 yillarda ultratezpishar kuzgi bug‘doyning Flesh, Ultra va Chillaki navlarining dala unuvchanligi o‘rganilgan. Tadqiqot natijalariga ko‘ra, Flesh va Ultra navlari har ikki yilda ham nazorat naviga nisbatan yuqori unuvchanlik ko‘rsatdi. Eng yuqori dala unuvchanligi Flesh navida qayd etilib, uning istiqbolli nav ekanligi aniqlandi.
