Efficiency of breeding strategy where grandparents — but not parents — contribute equally to the breeding population

Abstract: Abstract• The objective was to optimise the strategy for maintaining the genetic balance in long-term breeding where the grandparents contribute equally to the breeding population, but the parents do not.• The annual genetic progress under a budget constraint was compared for a number of scenarios. The factors considered were: genetic parameters, recruitment population size, mating number per grandparent, cost of plants and parents, selection age and time components. Phenotypic selection forward was assumed. U… Show more

“…Thinning to remove inferior trees has further reduced the genetic base which has been further narrowed down, as only 26 % trees contributed to the gene pool. Danusevicius and Lindgren (2010) recommended restriction in number of parent trees per grandparent in an orchard for sustaining diversity and gain based on heritability of the trait.…”

“…Mating system may vary in different populations which can have a significant impact on allelic frequency and performance of the crop (Rao and Hodgkin, 2002). For maintaining genetic diversity in an orchard it is necessary to optimize (Danusevicius and Lindgren, 2010) the number of genetically unique individuals that contribute to gene pool. The number of individuals required to maximise gain for a given diversity can be optimised (Funda et al, 2009) if the relationship between these factors is known.…”
