Evaluation of the Yield and Quality Properties of Some Potato Varieties and Candidate Genotypes in Yenisehir-Bursa Ecological Conditions

Abstract

The experiment was implemented to evaluate the yield and quality properties of potato varieties and candidate genotypes were examined in 2019 growing seansons under Yenisehir-Bursa conditions. The experimental design was a "Randomized Complete Block Design" with three replications. Eight potato candidate genotypes ("EA10", "GAF4", "MK-2", "AH-11", AFK-3", "AA12", "HA5", "LOH3Y") which were developed by Associate Proffessor Rahim Ada and four potato varieties (Marabel, Florice, Melody, Lady Olympia) were used as plant material in this experiment. The plant height (cm), number of stem per plant, number of tuber per plant, total tuber yield (t ha-1), dry matter content (%), yield of chips (%), yield of french-fries (%) were examined. According to results of this experiment, significant differences were found in all properties among the potato varieties and candidate genotypes statistically. The plant height changed between 48.3-107.3 cm, number of stem per plant was 4.6-10.0, number of tuber per hill was 4.3-16.6, total tuber yield per hectare was 8.9-52.1 t. In addition, dry matter content changed between 16.7-25.0 %, yield of chips was 36.1-60.3 %, yield of french-fries was 55.0-70.8 %. The highest total tuber yield was obtained from Florice variety (52.1 t ha-1) and "GAF4" potato candidate genotype (49.6 t ha-1) and the lowest total tuber yield was obtained from "AFK-3" potato candidate genotype (8.9 t ha-1, respectively). The experiment results indicated that "GAF4" potato candidate genotype was found promising.
