Technology of production of potato mini tubers in protected soil conditions

The production of potato planting material based on improved source material is widely used in potato growing. Further improvement of mini tuber growing techniques will increase crop yields in the commercial sector. Elements of potato varietal technology have been developed at the stage of mini tubers production in protected soil conditions. An experiment was conducted in a summer greenhouse within the city of Krasnoyarsk to assess the responsiveness of potato varieties common in Russia to the elements of agricultural technology when growing mini tubers. The objects of the study were the very early variety Meteor, early (early ripening) Felox, Rosara, Gulliver, Red Scarlett, Vega. Varietal specificity of potato varieties' responsiveness to indoor cultivation techniques has been established: pot volume, transshipment. The use of two-liter containers ensures maximum revenue and output of mini tubers for the varieties Rosara, Red Scarlett, Felox, and liter containers – Meteor, Gulliver. Minimum efficiency was achieved using five-liter pots. The influence of the “pot size” factor was maximum, amounting to 47.2% for the number of tubers and 63% for the weight of the tuber. The genotype accounted for 15 and 17% of the variability of traits, respectively. The Rosara variety responded positively to being transferred from a 0.2 l seedling container to a 2 l pot. The highest productivity of the Vega variety was obtained when planted in 1 l pots with subsequent decapitation. The average number of tubers in a pot was 6.2 pcs., tuber weight was 8 g. The obtained data can be used in the original seed production of the studied varieties. Taking into account the degree of influence of the genotype on other samples, it will be necessary to clarify the results.
