Grain element concentrations of 36 genotypes of wheat at six sites over two years.

Data represent the means of two replicate plots per genotype at Karnal, Hisar, Malda and one replicate plot per genotype at Kumarganj-reclaimed and Kumarganj-sodic sites in 2013–14 and two replicate plots per genotype at all six sites in 2014–15. Boxes represent the two mid-quartiles with the median drawn; whiskers are the 95% confidence limits; circles are the outliers.
