We grew 40 genotypes of corn ( Zea mays L.) in sand culture and evaluated the roots at 28 and 35 days after planting. Total root weight, root volume, and weight of nodal roots were significantly and positively correlated with root‐clump weight and root‐pulling resistance of mature plants under field culture. The percentage of seminal roots was negatively correlated. Evaluation of corn roots grown in a sand culture provides an efficient method for identifying genotypes with superior root types at an early stage of growth. Our results suggest that corn genotypes with vigorous root systems early in plant development tend to have superior root systems at maturity.
