Bernard (1972) studied a gene, Dt2, which hastened the termination of apical stem growth and decreased both plant height and number of nodes per plant. In a \u27Harosoy\u27 background, a Dt2 isoline had a 15% reduction in height and was three days earlier maturing but was similar in yield to Harosoy . There was some reduction in weight per seed associated with the Dt2 effect
