QTLs for rice flag leaf traits in doubled haploid populations in different environments

J. Cai, Zhang, M., Guo, L. B., Li, X. M., Bao, J. S., and Ma, L. Y., QTLs for rice flag leaf traits in doubled haploid populations in different environments, vol. 14, pp. 6786-6795, 2015.

Two rice doubled haploid (DH) populations derived from the crosses of ZYQ8/JX17 and CJ06/TN1 were used to detect quantitative trait loci (QTLs) for flag leaf length (FLL), width (FLW), and angle (FLA) under long-day conditions in Hangzhou (subtropical zone) and short-day conditions in Hainan (tropical zone), China. The four parents differed significantly in all 3 traits. FLL was found to be positively correlated with FLW in the 2 populations. A total of 30 QTLs were identified for flag leaf traits, with a contribution to the phenotypic variation of each QTL from 4.49 to 26.30%.
