Means followed by the same letters in the same column are not significantly different according to Duncan’s Multiple Range Test (). 0 equals completely smooth tubers/no cracks; 1 equlas 1–20% of the tubers skin rough/cracked; 2 equals 21–40% of the tubers skin rough/cracked; 3 equals 41–60% of the tuber skin rough/cracked; 4 equals 61–80% of the tuber skin rough/cracked; and 5 equals 81–100% of the tuber skin rough/cracked. Each value is a mean of seven replicates.
