COMBINATION OF APICAL MERISTEM AND CLONAL SELECTION IN ORIGINAL POTATO SEED PRODUCTION

Summary/Abstract: The paper presents the results of studying two main methods of healing plants from infections during original potato seed production for obtaining high-quality planting material in the Republic of Karelia. Clonal selection of the most productive generations of the Ladojsky and Charodey potato varieties was conducted in protected ground on the basis of the visual assessment of mini-tubers (obtained from apical meristem-improved plants) in terms of their number and size. The correctness of this selection was confirmed by using specific methods of multivariate statistical analysis. While obtaining the first field generation in open ground the productivity of selected clones and vegetative generation was evaluated without selection. The productivity of the Ladojsky and Charodey variety selected clones increased by 33 % and 26 %, respectively. Thus, with the help of mathematical methods it is possible to increase the efficiency of the best clones selection at the stage of obtaining mini-tubers.
