HERITABILITY ESTIMATES OF SOME QUANTITATIVE TRAITS IN POTATOES

Abstract

Broad-sense heritability (H) values of some quantitative traits in a potato population comprising 21 genotypes grown at Bornova, Izmir, Turkey during the 2013 and 2014 growing seasons were estimated by using the variance components analysis method. Based on the combined analysis of variance performed over two years, the following moderate to high level H values were found for plant height (0.77), leaf width (0.69), leaf length (0.71), single tuber weight (0.74), plant yield (0.60) and starch content (0.87).The expected genetic advance based on the selection of 25 % upper part was 8.2 cm for plant height; 0.5 for tuber number; 18.5 g for single tuber weight; 150.8 g for plant yield; 2.2 kg for plot yield and 1.9 % for starch content.
