Maize kernel row number ( KRN ) is an important agronomic trait. In this study, 13 quantitative trait loci ( QTL ) for maize KRN were identified in different environments using F 2:3 and F 2:4 populations developed from two inbred lines. These QTL are distributed on chromosomes 2,3,5,8 and 10, and the genic effects are additive or partially dominant. Using the BC 3 F 2:3 populations developed from the same parental lines, QTL of KRN located on chromosomes 5 and 10 were also identified in two environments. Three BC 5 F 2:3 populations were used to confirm the major QTL for KRN between ssr1430 and umc1077 on chromosome 10(q KRN 10). This result will facilitate the fine mapping and map‐based cloning of this major QTL in the future.
