Mean value (± s.d.m.) comparison was executed using Tukey’s HSD test, and statistically similar variables are grouped as indicated by the same letter (P < 0.05); n, number of replicates.

z)Yield and yield related major traits measured.

y)Values are represented by mean value of the group ± standard deviation represented by “SE” and number of samples in parenthesis represented by “n”. Means were compared using Tukey’s HSD test, and statistically similar variables are grouped by the same letter (P < 0.05).
