Abstract

The study aimed to compare the performances of clones selected for high low single plant yield in the greenhouse growing in the progeny test run in seedbed growing. A total of 104 plants were randomly selected among 1104 F1 plants and tuber yield of each plant was measured and the tubers were kept as clone. Assuming a normal distribution, the truncated selection was applied at the highest (Q1) and lowest (Q4) quartiles of the normal distribution at the s = 0.05; 0.10; 0.15; 0.20 and 0.25 selection pressures. Clones selected were grown in a seedbed nursery as progeny testing. The results can be summarized as follows: The progeny population could be separated into two distinct groups with mean values of 5.16 g and 1.35 g, at the s = 0.25 selection pressure. In the greenhouse the highest quartile at the s = 0.05 selection pressure had the highest mean of 6.40 g and reduced to 5.16 g at the 0.25 level. In the lowest quartile the lowest mean was 0.60 g at the s = 0.05 level and increased up to 1.35 g in the s = 0.25 level. The highest quartile (Q1) had the mean 49.51 g at s = 0.05 and reduced to 35.53 g in the s = 0.25. The lowest mean was obtained in the lowest quartile (Q4) at the s = 0.05 with a value of 24.30 g and increased up to 33.85 g at the s = 0.25 level. The highest amount of the difference between the highest and the lowest selection was obtained as 25.21 g at the s = 0.05 pressure level in the seedbeds.
