The Potato Clones Selected for High and Low Plant Yield in the F1 Generation of Atlantic × 101 (Nif) Cross

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.
