The study perpersents the influence of electron irradiation on on the phenology and productivity of potatoes inhabited by the fungus Rhizoctonia solani Kuhn. Potato samples were irradiated with the doses ranging from 0.02 kGy to 3.0 kGy. It was found that the pre-planting irradiation of seed potato tubers with the doses of 0.02-0.15 kGy led to a delay in plant development, and irradiation of tubers with over 0.2 kGy resulted in the death of plants. The maximum number of large tubers was obtained from samples irradiated with the dose of 0.15 kGy. The yield of potato tuber samples irradiated with the dose of 0.02 kGy corresponded to that of the control samples. Irradiation of potato seed tubers with a dose of 0.04 kGy led to a significant decrease in the colonization of the surface of tubers of the new crop with Rhizoctonia solani, while irradiation of potato tubers with a dose of 0.15 kGy completely eliminated the pathogen.

From a panel of 10 monoclonal antibodies (MAbs) prepared against specific isolates representing the three recognized strain groups of potato virus Y (PVY), i.e., common (PVYO), tobacco veinal necrosis (PVYN), and stipple streak (PVYC), seven were selected for serotype analysis. These MAbs were tested for reactivity with 52 PVY strains representing all three strain groups from an international collection. Within the PVYN strain group, five serotypes were identified and designated N1 to N5. The PVYO strain group was more diverse, and nine serotypes were defined and designated O1 to O9. Only one serotype, designated C1, was defined) within the PVYC strain group. The same panel of MAbs was used to test 632 PVY samples collected from potato seed certification plots in North America. Although no PVY(N) serotypes were found, all of the PVYO serotypes were identified, and several samples, tentatively assigned to the C1 serotype, were found.

Crop Research

The quality of potato seeds is important to support increased production. The majority of farmers do not certify potato seeds, which can result in various risks for potato seed production activities. This research aims to identify the risks of potato seed production and formulate risk control strategies for potato seeds production. The research uses house of risk method. The results of this study show thirty-nine identified risk events. The most impactful risk event was rotten potato. Thirty-two identified risk agents with two priorities must be handled first. The most effective ways in handling strategy are training, the certification of potato seed breeder farmers, potato seed certification, as well as purchasing breeder seeds from vegetable crop research center and from other seed breeders. This research suggests the needs to produce quality potato seeds by certifying potato seed and to update the competency certification of potato seed breeders.
