The influence of various factors on production original seed potatoes (mini crop)

In studies 2013-2015, studied different agricultural methods of production of original potato seed (greenhouse minitubers) with test tube microplants rehabilitated. The aim of research was to identify the best and technologically-based methods of preparation of planting material, planting dates, planting density in the cultivation of the improved seed potatoes. We used the method of accelerated potato breeding in the culture in vitro, based on the method of apical meristem and further cultivation of microplants in tissue tunnels. During the study it was determined the effect of rooting microplants exit potato minitubers per unit area. The highest survival rate (93%) was recorded in the variant with rooted plants with sparse planting (71.4 thousand units/hectare) and planting for the first time (June 10). However, the highest yield of minitubers 466.4 thousand units/hectare was obtained in the variant with seedling method for growing plants in combination with the planting period on 10 June and thickening landings to 142.8 thousand units/hectare. Regardless of the type of planting material (64% survival) seal landings to 142.8 thousand units/hectare helps to ensure a 347.1 thousand units/hectare minitubers. Thus, empirically it was found that the survival rate and planting density figures mainly affect the increase in the yield of potato minitubers from 1 hectare. The results allow efficient use of the spring time, with the ability to start the preparation of planting material in the laboratory. Also, this technology helps to minimize the crop area without compromising the quality and yield of seed minitubers.
