Statistical Mapping of Quantitative Trait Loci Controlling the Time to First Callusing in Oil Palm (Elaeis guineensis jacq.) Tissue Culture

An additional 400 genetic markers (126 rflps, 274 afus) were successfully mapped on the earlier developed linkage maps using 871f1 progenies derived from deli dura x yangambi pisifera cross. this resulted in a denser map with coverage length of1, 714cm and 1, 225caifor pisifera and dura, respectiuels. further exploration to search for quantitative trait loci (qtl) associated with time to first callusing (7fc) was carried out by kosambi interval mapping using the computer program mapqtl version 4.0. the tissue culture trait data showed a continuous distribution in this paper, three likelihood qtls were detected in pisifera and two qtls in dura at 99% an d 95% signijicant thresholds. these qtl locations can be designated as statistically signijicant for contributing to the variation of tfc. therefore, the information points to a genomic loci affecting tissue culturability in oil palm.
