#Leaf a* recorded negative values for green leaves, hence data scaling was applied to calculate variability, heritability and genetic gain.
*, Shapiro–Wilk test statistic values at P ≤ 0.001 for all parameters except for peel b* values (P= 0.969).
Variability <10% (low), 10–20% (moderate), >20% (high).
Heritability 0-30% (low), 31-60% (moderate), >60% (high).
GAM <10% (low), 10–20% (moderate), >20% (high).
SW, Shapiro–Wilk test of normality.
GCV, genotypic coefficient of variability; PCV, phenotypic coefficient of variability; h2, heritability in broad sense; GAM, genetic advance as a per cent of mean.
