Heritability Estimates and Relationship of Certain Characteristics in Potatoes
M. ERASLAN, M. B. YILDIRIM
Abstract
Broad sense heritabilities and linear correlations for 10 characteristics of 20 potato genotypes were estimated based on 2 locations and 2 years. Plant height gave the highest and plant yield gave the lowest heritability estimates. Except for dry matter content all the traits studied seemed to be affected by the genotype x environment interaction. Therefore, the testing of genotype x environment interaction should be carried out at multiple locations in multiple years. There was a positive correlation of plant yield with plant height, number of main stems, number of tubers and avarege tuber weight. A positive correlation between dry matter and starch; negative correlation between dry matter and reducing sugar contents were also estimated.
