Current version: V1.0; Released 8 July 2014; Updated 16 April 2015
Genetic studies of clonal species are conducted in populations of clonal F1 hybrids which are the progenies from the hybridization between two heterozygous clonal lines. In self- and cross-pollinated species, double crosses are commonly made between four inbred lines in order to extend the genetic diversity in genetic studies and plant breeding. The unknown linkage phases in clonal F1 and greater number of alleles in double crosses complicate the genetic analysis methodology. GACD is user-friendly and integrated genetic analysis software capable of building linkage maps and mapping quantitative trait genes for clonal F1 and double cross populations.
Three functionalities are implemented in GACD V1.0.
(1) BIN, binning of redundant markers;
(2) CDM, construction of female, male and combined linkage maps;
(3) CDQ, mapping of additive and dominance genes. Three QTL mapping methods are available, i.e., Single Marker Analysis, conventional Interval Mapping, and Inclusive Composite Interval Mapping (ICIM).
