Abstract: Based on selection of maize inbred lines with different nitrogen (N) use efficiency (NUE), the heterosis of NUE was analyzed and how to choose parents in the breeding for NUE was investigated by NC-II design. The results showed that, among the 72 crosses derived from 18 inbred lines, heterosis of se
