Tuber Production

Certified potato seed tuber usage is one of the most important steps for production of high yield and quality potatoes. For this reason different seed tuber production methods have been developed. Among these methods, mini tuber production is the most popular one. In order to produce mini tubers, firstly potato plants are produced in vitro, and these plants are transferred to an environmentally-controlled greenhouse. Thus, disease- and virus-free mini tubers are produced as seed tubers. However, in vitro section of mini tuber production creates problems like storage and transfer of in vitro plants, and adaptation period of the plants to greenhouse conditions. In vitro micro tuber (MT) formation has been selected as a solution of these problems. The aim of the study was to produce micro tubers from 15 different genotypes and evaluate their micro tuberization performances to determine the genotype effect on MT formation. 3 varieties, 3 breeding lines and 9 different genotypes from International Potato Center (CIP) were selected for the study. For this purpose, micro tubers are produced in vitro by using Murashige and Skoog (MS) medium supplemented with 8% sucrose and 0.1 mg/L thidiazuron (TDZ). All experiments were conducted under dark conditions and 22/16 °C (8/16 h) temperature cycle. The micro tuberization performances were evaluated according to MT number per plant, MT formation rate (%), MT weight per plant (g), mean MT weight (g), mean MT diameter (mm). Differences between micro tuber production performances of different genotypes were determined and CIP395017.229 was identified as the most promising genotype to produce micro tubers.

Potato Seed Tuber

Recent methodological developments have uncovered the etiological diversity of the potato blackleg and soft rot Pectobacteriaceae. At least five species in the genera Dickeya and Pectobacterium have been confirmed to cause blackleg on potatoes in Finland. The bacteria are seed borne and remain latent in the tuber until conditions favourable for growth, multiplication and infection prevail. Tubers could be infected by one or more of these species. This short communication is based on the results of molecular detection data collected for more than 14 years from potato seed lots produced in Finland. Diagnostic PCR assay specific to Dickeya solani, Pectobacterium atrosepticum, Pectobacterium carotovorum, P. brasiliense and P. parmentieri revealed that potatoes are infected by one or more of these species; it also revealed that single species infection is more common than multiple colonization. An event of simultaneous occurrences of different strains from the Pectobacterium species appears to be more frequent than that observed between Dickeya and Pectobacterium species. The absence of co-occurrence of Dickeya solani and Pectobacterium atrosepticum is intriguing.

Potato Plantlets

In vitro-propagated potato cv. Ostara and Bintje plantlets were transplanted in a greenhouse at 350 plants/msuperscript 2 under tuber-inducing conditions. Plants growing undisturbed were compared with plants from which tubers >=0.3 g were removed in a single non-destructive harvest 3-8 weeks after transplanting. In undisturbed plants tuber initiation slowed down 4 weeks after transplanting, and an average of 2 tubers/plant (average weight 5 g) were harvested in 11 weeks. After a non-destructive harvest new stolons and tubers were initiated, but overall and tuber growth rates were reduced, probably as a result of the combined effects of tuber removal, root damage and deep replanting. Highest tuber numbers and lowest growth rate reductions occurred when growth was at its maximum. The highest number of tubers/plant (3.44) was achieved with non-destructive harvesting 6 weeks after transplanting, but FW/tuber decreased with delay in harvesting from 1.97 to 0.77 g. Using this non-destructive harvesting procedure >1400 and 2400 minitubers >=0.3 g (average weight 1-2 g) could be produced per msuperscript 2 within 8 and 9 weeks of transplanting by Ostara and Bintje, respectively, and would be suitable for use in large-scale seed tuber production programmes.
