Abstract: This document is the Users Manual of the Wheat Coefficient of Parentage System, a system for calculting coefficients of parentage between different wheat cultivars based on their individual pedigrees. The goal of the Wheat Coefficient of Parentage (WCOP) system is to calculate coefficients of parentage between different cultivars based on their individual pedigrees. The coefficient of parentage between two genotypes provides an estimate of the genetic relationship between them, based upon analysis of their pedigrees. WCOP uses information about crosses, pedigrees and selection histories of germplasm used in the CIMMYT Wheat Program, stored in the Wheat Pedigree Management System (WPMS). WPMS keeps track of female and male parents for each cross recorded in the system, which permits the building of the whole cross tree for any genotype (a cross associated to a selection history), up to the landraces, genotypes with unknown parents. For genotypes existing in WPMS, WCOP will find all their ancestors going back up to the ancestral parents, and will build the corresponding progeny parent trees. WCOP will write the progeny parent trees data, in formatted files that will be used as input files for the RCL program, which will generate the matrix of coefficients of parentage based on the Rodgers & Cox algorithm.
