Quantitative trait locus detection associated with kernel length in maize
Journal Title: Scholars Academic Journal of Biosciences - Year 2014, Vol 2, Issue 12
Abstract
Mo17 and Huanzaosi are two elite maize (Zea mays L.) inbred lines, and widely applied in breeding cultivation varieties and realizing genetic mechanism in China. In this presented study, a recombinant inbred line (RIL) population bred from the two maize materials as parents was used for quantitative trait locus (QTL) mapping for kernel length. The results showed that kernel length is a quantitative trait controlled by multiple genes according to its phenotypic investigation, but no QTLs controlling kernel length were identified via Interval Mapping and Composite Mapping methods, this could probably be caused from less markers included in the established map. The results are beneficial for us in realizing genetic basis of kernel length in maize breeding program.
