Two wheat ( Triticum aestivum L.) cultivars, one semidwarf (‘Israel M68’) and the other conventional height (‘Olympic’) were grown for 10 days in five root media in a growth chamber to determine differences in seminal root growth and the effect of root medium on seminal root growth. Differences were obtained between the cultivars for number of seminal root axes, maximum depth of penetration of the seminal root axes, number and length of lateral roots and total length of seminal root. Maximum expression of most variables was in a 1‐ to 2‐mm sized sand fraction. Significant cultivar ✕ root media interactions were obtained for shoot dry weight and root dry weight.
