Kernel Size in Relation to Hardness Score and Other Physicochemical Characteristics of Wheat

Abstract

 Twelve Pakistani wheat cul ti vars were studied for the effect of kernel size on the physicochemical characteri stics. Thousand -kernel weight (TKW) ranged from 40-48.2 g for large kernels, 32-39 g for medi um size kernels and from 24-29.2 g for small kernels. A highly sign ificant relationship (r = 0.650) was found betwee n TK W and NIR hardness score. Shrivelled kernels contai ned the highest protein content and broken kernels, the lowest Other consistently positive but statistically non-significant relation shi p was observed between TKW and the gl uten content No consistent relationship was found between the gl u ten i ndex, th e falling n umber, the  moi sture content and the kernel  size and form.
