“…They are the result of different-size minitubers used for planting; smaller from aeroponics (9-10 g) and larger from the soil (15-22 g) (Rykaczewska 2016). The importance of the size of minitubers in their productivity was also pointed out by other authors (Ranalli et al 1994, Struik 2007, Radouani and Lauer 2015. However, the larger number of minitubers produced in aeroponic than in soil, allows for better economic effect with the use of this innovative production system.…”

The aeroponic system is a viable technological alternative for potato minituber production within a potato tuber seed system. The aim of the study was to evaluate the productivity of potato minitubers grown in aeroponic culture and collected in 14 successive periods of the growing season. The minitubers of cvs. Ametyst and Tajfun were tested in an experimental field after a storage period. It was found that cv. Ametyst was characterized by higher yield and number of tubers than cv. Tajfun. Yield of cv. Ametyst averaged 42.6 t/ha, and cv. Tajfun 37.3 t/ha. The number of tubers over 3 cm of cv. Ametyst averaged 644.2 per ha, and cv. Tajfun 437.7 per ha. The yield and number of tubers was dependent on the physiological age of minitubers harvested on successive dates. Comparing the productivity of minitubers grown in aeroponics and in the soil, a significant difference was found in the number of tubers with a transversal diameter over 3 cm. There were more daughter tubers from minitubers grown in soil. They are the result of different-size minitubers used for planting, smaller ones from aeroponics and larger from soil.

“…This situation is mainly due to limited information on greenhouse and field performance comparison between microtubers and plantlets (Joung et al, 1993;Ranalli et al, 1994;. Due to a recent, rapid expansion of potato acreage in the Province of Alberta, some of the plantlet and nuclear seed producers turned to microtubers as a supplement to plantlet type of the propagule which can be used successfully in the early stages of seed production.…”

“…Microtubers or in vitro produced tubers are another type of propagule which could also be utilized in the production of pathogen-free seed potato material. Microtubers are small (0.02 -0.70 g) tubers produced from nodal cuttings or on complete plantlets using a specific growing medium (Hussey & Stacey, 1984;Ranalli et al, 1994). Utilization of microtubers has been postulated in the elite seed potato production systems by several authors, for almost two decades (Hussey & Stacey, 1981;, Coltman & Kostichka, 1993.…”

“…As mentioned earlier, several authors presented a potential for microtubers and minitubers in seed potato production systems since the propagules appear suitable for use in the first year of the seed program in which the number of conventional field multiplications is to be reduced drastically . Both types of propagules can be planted directly to the field (Ahloowalia, 1994;Ranalli et al 1994). Earlier studies also showed that along with in vitro plantlets, microtubers can be successfully used for speeding up multiplication at the start of seed programs (Mastenbroek & Eising, 1987;.…”

PhD thesis, Wageningen University and Research Centre, Wageningen, The Netherlands, 166 pp., English and Dutch summaries.Micropropagation (in vitro propagation) has been introduced to seed potato production programmes more than two decades ago. The research reported in this thesis studied possibilities of improvements to micropropagation methods commonly used in commercial laboratories. The focus was placed on seed potato growers in Western Canada who either produce the tissue culture plant material themselves and use it for the production of minitubers (nuclear tubers) in their own operations, or acquire it prior to planting. The autotrophic micropropagation (in C0 2 (1500 ppm) enriched atmosphere, no sucrose in the medium) of Russet Burbank variety showed its usefulness for the small commercial laboratories where often the full sterility is difficult to maintain. Autotrophically grown cultures produced stems very similar to conventionally grown in vitro cultures (no significant differences in length, number of nodes and dry weight). Also, the conventionally propagated cultures benefited from CO2 enrichment during the 4 week growing period by a 20% increase in the number of nodes per stem and a 50% increase in stem dry weight (doubled stem length).The use of continuous low red light (690 nm) at 3 uxnol nf 2 s~l PPFD and 30 g f~' sucrose in the medium during the in vitro low temperature (4°C) storage of potato cultures were beneficial for maintenance of vigorous, high quality cultures with a high re-grow capacity. In small tissue culture laboratories, installation of a simple low light device in the regular refrigerator would improve maintenance of the high quality of the stored cultures.Significantly better production of microtubers (number of tubers and weight) was observed on solid (agar) than on liquid media, and under the 8 h photoper...

Currently in vitro plantlets and microtubers provide the basis for pre-base production of potato seeds, from which minitubers are produced under covers -they serve later as seed material to be planted in the field. The aim of the research was to determine the possibility for multiplication of material produced in vitro directly in field conditions. The research assessed PVY, PVM and PLRV infection of potato tubers derived from plants grown directly from in vitro plantlets, microtubers, minitubers and traditional seed potatoes planted in the field at different times. Moreover, testing in laboratory conditions, the susceptibility of these plants to virus infection was determined for the case of artificial inoculation of Myzus persicae and Aphis nasturtii. It was found that the infection of tubers derived from in vitro plantlets and microtubers was greater than that of seed potatoes and minitubers. Yet it seems that the reason for their higher infection level resulted not from the plant's sensitivity or its greater attractiveness to aphids but from a largely unknown cause. Earlier planting of microtubers and in vitro plantlets in the field in case of the more resistant cultivar and certainly later in relation to the main time of planting had an impact on limiting the PVY and PVM infection of potato tubers. Hence multiplication of microtubers and in vitro plantlets in field conditions could be very economical using cultivars which are relatively resistant to viruses. However, adopting a later than usual planting period (end of June) and applying an additional protective cover (such as non-woven agricultural fabric) in the first period of a plant's growth, promotes multiplication of microtubers and in vitro plantlets in field conditions for cultivars with low resistance levels.Resumen Actualmente, las plántulas in vitro y los microtubérculos suministran el sustento para la producción de semillas pre-básicas de papa, de las cuales se producen los minitubérculos bajo cubierta, que después sirven como material de siembra para ser plantado en el campo. El propósito de esta investigación fue determinar la posibilidad para multiplicación de material producido in vitro directamente bajo condiciones de campo. La investigación analizó la infección por PVY, PVM, y PLRV en tubérculos derivados de plantas que crecieron directamente de plántulas in vitro, microtubérculos, minitubérculos y semilla-tubérculo tradicional de papas sembradas en el campo en diferentes tiempos. Además, en pruebas de laboratorio se determinó la susceptibilidad de estas plantas a la infección viral mediante inoculación artificial de Myzus persicae y Aphis nasturtii. Se encontró que la infección de tubérculos derivados de plántulas in vitro y microtubérculos era mayor que la del tubérculo-semilla y minitubérculos. Sin embargo, parece ser que la razón para su mayor nivel de infección fue el resultado, no de la susceptibilidad de la planta o por su mayor atractivo a los áfidos, sino por otra causa mayor desconocida. La siembra temprana de microtubér...
