Verkkobreeding programs seek to identify genetically superior parents of the next generation, typically as a function of an index that combines information. Verkkowe selected 72 top performing lines based on breeding values for grain yield to create an elite core panel (ecp) representing the genetic diversity in. Verkkothis paper first summarises the key issues facing many key investor stakeholders, and then describes at a high level the tools available to design and optimize breeding. Verkkocombining recurrent selection within elite germplasm with a systematic introgression from exotic germplasm in the recurrent introgressive population enrichment (ripe). Verkkothe best bridging individuals become potential parents for introduction in the elite breeding program. This strategy aims to close the gap in. Verkkomost breeding programs have a crossing stage to recombine elite parents, stages to multiply progeny and/or generate progeny derivatives such as. Verkkowe propose to consider genomic selection and optimal cross selection to recurrently improve genetic resources (i. e.
