Abstract：Dwarf germplasm resources have significant utilization value in maize breeding.In this study, the hybrids were obtained from maize dwarf mutant 52333 and its near -isogenic lines crossed with inbred lines of Lx9801,C607,C785,S121,Zheng 58 and Chang 7 -2,respectively.With these hybrids as materi-als,the genetic effect of gene Dt was studied.The results showed that the materials containing Dt gene had re-markably reductions in plant height and ear height,and the reducing amplitude ranged in 67 ~112 cm and 34 ~56 cm,respectively.Dt gene was considered unfavorable for increasing maize yield because of its nega-tive effect on yield characters such as ear length,ear diameter,ear rows,kernel weight per ear.
