Abstract: To improve the plant traits of the maize inbred lines R2228/R5518, the performance and segregation characteristics of 13 plant traits for 2/3 F2 populations chosen from its crosses with 21 introduced hybrids were analyzed, and compared with R2228, R5518 and the maternal inbreds‘Zheng58’, and PH6WC for 2 broad utilized famous hybrids in this study. The results showed that great differences and broad segregations existed among the F2 populations for all traits, with variation coefficients 7.97%- 64.00% . Comprehensively considering the performance of all plant traits, P523/P520 were chosen as the major populations to improve inbred R2228/R5518 and develop new inbred lines with elite plant traits in further research.
