AbstractA large insert Sorghum propinquum BAC library has been constructed to analyze the physical organization of the sorghum genome and to facilitate positional cloning of sorghum genes and QTLs associated with the early stages of grain crop domestication. This library was established from 12 different ligations using high-molecular-weight DNA generated from either one cycle or two cycles of size selection. This library consists of 38 016 BAC clones with an estimated average insert size of 126 kb and coverage of 6.6 genome equivalents. The 6.6 genome-equivalent BAC library of S. propinquum provides a 99.7% probability of finding one or more BACs that contain genes of interest. Twenty mapped DNA probes, ten homologous and ten heterologous, were used to screen the library, and 121 positive clones were identified, 6.05 per locus or 6.37 per probe.
