The Tammi barley variety is a standard among mid-maturing varieties used under conditions of Central Yakutia. It is characterized by high rapid maturation with a vegetation period of about 67 days, making it one of the earliest among the studied germplasm samples. Tammi differs in optimal plant height and low tillering, which contributes to its resistance to lodging, an important factor for successful cultivation in the region's complex climatic conditions.
During multi-year research conducted on the experimental fields of the Yakut Research Institute of Agriculture, Tammi demonstrated stable yield and grain quality indicators. Although some new germplasm samples, such as Byyan and Dygyun, surpassed Tammi in yield, this variety remains a benchmark thanks to its balanced characteristics and reliability. The 1000-grain mass of Tammi is somewhat lower than that of some hybrids, however, its grain possesses a good nature, indicating high raw material quality.
Tammi is widely used in agriculture to obtain quality barley suitable for various purposes, including feed and grain production. Its resistance to lodging and rapid maturation make the variety in demand for cultivation in regions with a short vegetation period and unfavorable weather conditions. Thanks to these properties, Tammi serves as the basis for breeding programs aimed at creating new, more productive and locally adapted barley varieties.
