“…But such methods fail to adequately control the disease. Cultivating varieties of potato that are resistant to common scab is the most practical, effective method of controlling the disease (Kobayashi et al 2002, Kobayashi 2005. However, few varieties of potato in Japan are scab resistant.…”

“…Their use, therefore, could lead to increased populations of newly invading pathogens because normal antagonism and competition between microorganisms would be eliminated (Soltani et al 2002). Thus, cultivating common-scabresistant varieties of potato is the most practical and effective method for control of the disease (Kobayashi et al 2002;Kobayashi 2005). However, almost all of the existing Japanese varieties of potato are susceptible to common scab.…”

Fungi, actinomycetes, and bacteria isolated from soil and plant samples from a potato field in which wild oat (Avena strigosa) had been pre-cultivated were screened for microorganisms that can be used as biocontrol agents for common scab of potato. Of 342 isolates assessed in initial pot trials for their suppressive effect on the severity of potato scab caused by Streptomyces turgidiscabies, 26 isolates were selected as antagonistic candidates based on their ability to reduce disease severity, then tested in a second pot trial. Of the 26, five actinomycetes, isolated from either the rhizosphere soil of wild oat or the soil adhering to potato stolons and tubers, were selected as antagonists. A comparison of partial sequences of 16S rRNA genes from the five isolates indicated that they belong to the genus Streptomyces. Of these five, WoRs-501 most strongly inhibited in vitro mycelial growth of S. turgidiscabies and was also the most effective in suppressing potato scab in a third field pot trial. In that pot trial, a 10% (v/v) mix of WoRs-501 (6.2 9 10 8 colony-forming units [CFU]/g dry mass) decreased the disease severity by 78-94% in comparison with the untreated control at 5 9 10 4 to 5 9 10 6 CFU S. turgidiscabies/g dry soil. WoRs-501 also grew well in vitro at a wide range of pH levels and temperatures. These results suggest that WoRs-501 is a promising candidate for biocontrol of potato scab.

“…Irish Cobbler (Japanese name "Danshakuimo") (Clark and Lombard 1951) is the leading table-stock potato variety in Japan (Mori et al 2007), which is sold not only in the fresh market but also in the form of processed food for salads and croquettes. The tuber of Irish Cobbler has deep eyes that result in a low efficiency of peeling of the tuber skin, and shows notable enzymatic browning in freshly cut tuber slices, in addition to postcooking discoloration (Kobayashi et al 2002). The tubers also have a low tolerance to mechanical damage and are frequently bruised (Takada et al 2000).…”

Haruka is a new table-stock potato variety with parti-colored red/white-skinned tubers, white flesh, medium maturing and good culinary quality. It was selected from a cross between T9020-8 as the female parent and Sayaka as the male parent, and was released in 2007. Agronomic characters of the Haruka were checked from 2003 to 2007. Its marketable yield is 103% of the Sayaka and 124% of the Irish Cobbler. The average size of a tuber was 104 g. The starch value of Haruka was 16.2%. Dormancy period of the tuber was 105 days. In comprehensive evaluations of product quality, Haruka tubers shows a little disintegration of the flesh after boiling, the texture was rated as pasty, and the boiled tuber had favorable taste. Haruka was superior or equally good to Irish Cobbler and Sayaka for salad quality and had a high processing ability for chilled potato, whereas it was not suitable for chips and french-fry. Haruka is resistant to the golden nematode, and good resistant to brown rot and tuber rot, while it is susceptible to potato virus Y, common scab and foliage late blight.
