Ecological and geographical testing of potato varieties with pigmented flesh color.

Introduction. According to the results of statistical data in the Volgograd region, the area under potatoes has increased by 877.05 hectares since 2022 and amounted to 3906.95 hectares in 2023. The current trend allows us to judge potatoes as the most popular, often found in the diet product. However, do not forget about the risks that arise as a result of excessive consumption of this product. Agroecological testing of table varieties for healthy nutrition and their assessment of adaptive capacity will allow expanding the potato assortment with a set of biochemical indicators for the interested part of the population, and the results obtained will contribute to a larger-scale production of this product in the conditions of the Volgograd region.

The purpose of the research. Agroecological testing of potato varieties and hybrids with pigmented pulp in the conditions of the Lower Volga region.

Object. Five varieties and two hybrids of potatoes with a high content of anthocyanins.

Materials and methods. The experiments were laid on an experimental irrigated area of the Volgograd State Agrarian University. The zoned Nevsky variety was the control. The planting rate is 40 thousand pieces per hectare. Zonal cultivation technology and an optimized water consumption system were used with the maintenance of the soil water regime of at least 80% HB in a layer of 0.4 m due to 13-15 watering at a watering rate of 240 m3/ha and an irrigation rate for vegetation of 3120-3600 m³/ha, the coefficient of ecological stability was determined by the method of S. A. Eberhart, W. A. Rassel.

Results and conclusions. The conducted research allowed us to identify promising, highly productive and plastic varieties resistant to stress factors of the region. Among the studied potato varieties and hybrids with pigmented pulp, the hybrid 16182 and the Gourmet variety bred on the basis of the A.G. Lorch Potato FITZ can be considered the most promising for cultivation in the conditions of the Volgograd region. Also, when cultivating potatoes using intensive technology, it is recommended to cultivate the Northern Lights variety.
