Genotype Environment Interaction in Potato : Genotype Environment Interaction Shown by Yield and Yield Components in Potato (Solanum tuberosum L.)

In the present investigation, 30 different potato genotypes were evaluated for 3 consecutive years. The estimates of different components of variation and coefficient of variability, such as phenotypic, different interaction and error were more or less high for yield, number of leaves/plant, number of tubers/plant and number of eyes/ tuber, which indicates the wide scope of improvement of these traits through selection. The highest of h2b was recorded for tuber yield and lowest in number of tubers/plant.Path coefficient analysis showed that potato genotypes could be grouped into 6 different clusters and for the inprovement of potato, the genotypes should be selected I, II and IV.
