Abstract: Clonal species are common among plants. Clonal F₁ progenies are derived from the hybridization between two heterozygous clones. In self- and cross-pollinated species, double crosses can be made from four inbred lines. A clonal F₁ population can be viewed as a double cross population when the linkage phase is determined. The software package GACD (Genetic Analysis of Clonal F₁ and Double cross) is freely-available public software, capable of building high-density linkage maps and mapping quantitative trait loci (QTL) in clonal F₁ and double cross populations. Three functionalities are integrated in GACD version 1.0: binning of redundant markers (BIN); linkage map construction (CDM); and QTL mapping (CDQ). Output of BIN can be directly used as input of CDM. After adding the phenotypic data, the output of CDM can be used as input of CDQ. Thus, GACD acts as a pipeline for genetic analysis. GACD and example datasets are freely available from www.isbreeding.net.
