“…In the present study, differences in plant habit recorded during growth in 5 out of 7 cases resulted in a significant yield decrease (P < 0.01). No signs of disease on the surface of the tubers in the form of cracks in the skin were found, as reported by Whitworth et al (2019). It should be emphasized that the above studies were conducted on other cultivars, and a different strain and concentration of Cs was used as the inoculum.…”

“…Research has shown that the cultivar has a significant impact on the level of infection, expression of symptoms and yield decrease. According to Whitworth et al (2019), knowledge about the type of symptoms and the time of their occurrence on potato plants of new cultivars is important for the producers and manufacturers. The absence of Cs cells in certified seed material does not mean that there will be no positive samples in commercial production (Kudela 2007).…”

“…In the present research, a detailed assessment of plant infection during growth was omitted due to different weather conditions and pressure from other pathogens and pests in a given year. In contrast with the research by Whitworth et al (2019), in the present study, a single dose of bacterial inoculum was used, and plant fragments during growth (after flowering) and after harvest were analysed. In the present study, the number of disease symptoms on leaves and stems was low.…”

“…Current knowledge about the plant-pathogen interaction is insufficient in view of the susceptibility of various potato cultivars to biofilm formation by Cs (Marques et al 2003). Early detection during plant growth and the differences in disease symptoms among currently grown cultivars are of great importance for the potato industry (Whitworth et al 2019). The sources of the latent form of the disease, as well as the biotic and abiotic conditions that cause the occurrence of symptoms, have not yet been specified in detail.…”

The aim of this study was to determine the response of potato cultivars to Clavibacter sepedonicus (Cs) infection in a field experiment. The research focused on the infection in a latent form as it is a risk for unnoticed spread. A total of 18 cultivars were tested in the years 2013–2016. Symptoms of the disease were observed on the leaves during growth and in tubers after harvest and after storage. The infection incidence was determined by microscopic observation of leaf and tuber samples stained by the IFAS method. A diverse response of potato cultivars to Cs infection was found. The lowest number of asymptomatic infected plants was found in cultivars ‘Vineta’, ‘Bila’ and ‘Irga’. As for cultivar ‘Stasia’, the entire tuber yield was latently infected by Cs. A low or medium concentration of Cs cells in leaves did not change significantly or increased depending on the potato cultivar. A higher incidence of tubers with disease symptoms was found after the storage period. In eight of the cultivars tested, the level of tuber infection by Cs confirmed microscopically after harvest was significantly correlated with the occurrence of disease symptoms in tubers after the storage period.

Potato is important food for half population of the world particularly population in Europe and America. Beside it is as carbohydrate source, potato can be used as main food for diabetes people, replaces the rice due to it contains low calories. In developed countries, particularly in Indonesia, it is also as diversify food for medium and highland people. The research was conducted in Selayo Tanang Buki Sileh, Lembang Jaya, Solok regency, West Sumatera, Indonesia from May to August 2017. The research aimed to study the interaction between indigenous rhizobacteria and manure to the growth and yield of red potato. The factorial design in Completely ranzomized design (CRD) with 2 factors was used in this reserach. The first factor was rhizobacteria isolates (no isolate, A2.1b2; A3.1a5; B1.2a2) and the second factor was the manure with dose 30 ton/ hectare (chicken, quail, and cattle). The potato variety that used in the assay was PING 06. The data was analyzed by analysis of variance with Honestly Significant Difference/HSD test in 5%. Generally, the result showed that there was no interaction between rhizobacteria isolates and manure to growth and yield of red potato. A2.1b2 was the best isolate for fresh weight of tuber per plant, per plot and per hectare of red potato plant and chicken manure could increase the growth and yield of red potato plant (11.73 ton/hectare).

The results of the studies carried out over the last 50 years have not provided a clear answer to questions concerning the interaction between Clavibacter sepedonicus (Cs), potato and the environment. The reason is insufficient knowledge of the biology of the causal agent of ring rot, problems of research methodology and the influence of many environmental and biotic factors on the degree of plant infestation. The research conducted in the years 2013–2016 in the Plant Breeding and Acclimatization Institute – National Research Institute concerned the determination of the influence of weather conditions, involved the influence of temperature and Sielianinov hydrothermal coefficient on the development of Cs bacteria in stems and progeny tubers, as well as the occurrence of disease symptoms on plants and in tubers of eight potato varieties. It was found that genotype had the greatest impact on leaf and tuber infestation, while weather conditions were less significant. The results of correlation analysis indicate that the weight of tubers of plants infected by Cs increased statistically significantly with increases in air and soil temperature. On the other hand, air and soil temperature in the initial vegetation period did not significantly affect the number of potato plant tubers infested by Cs. In a 4-year experiment, it was not shown how air and soil temperature and the Sielianinov hydrothermal coefficient affected the degree of potato leaf and tuber infestation. In most cases, potato infestation by Cs caused a decrease in yield.
