The evaluation method of potato genotype resistance to blackspot bruise
- Potato Research Institute, Havlíèkùv Brod, Èeská republika
In 2001-2003 a method for the evaluation of potato genotype (genetic resource) resistance to blackspot bruise was verified. Thirty tubers of 25 varieties and hybrids of Solanum tuberosum L. were evaluated using electronic pendulum MIDAS 88P. The analysis of variance showed a significant difference among the individual varieties and hybrids and among years as well. An evaluation scale was established for the assessment of potato genotype (genetic resource) resistance to blackspot bruise. Varieties and hybrids were included in the new designed evaluation scale in scores of 7 (high resistance) up to 9 (very high resistance), which could be regarded as suitable genetic resources in breeding for the improvement of this character. From the evaluated set, the suitable varieties are: Carmona, Agria, Annabelle, Futura, Impala, Adora, Granola and Inova and the suitable hybrids: YP 91-123 and VDW 94-76.
