Mapping quantitative trait loci and predicting candidate genes for leaf angle in maize

Leaf angle of maize is a fundamental determinant plant architecture and an important trait influencing photosynthetic efficiency crop yields. To broaden our understanding the genetic mechanisms leaf formation, we constructed F 3:4 recombinant inbred lines (RIL) population to map QTL for angle. The RIL was derived from cross between model line (B73) with expanded elite (Zheng58) compact architecture. A sum eight were detected on chromosome 1, 2, 3, 4 8. Single explained 4.3 14.2% variance. Additionally, some confirmed through heterogeneous family (HIF) approach. Furthermore, twenty-four candidate genes predicted whole-genome re-sequencing expression analysis in qLA02-01and qLA08-01 regions. These results will be helpful elucidate mechanism formation benefit clone favorable allele Besides, this develop novel varieties ideal marker-assisted selection.
