Advancing Diploid Potato through Selfing Most diploid potato plants are self-incompatible and will not set fruit on selfing, making the development of inbred lines difficult or impossible. Peterson et al. found self-fertile plants segregating within an F1 potato population then used a whole genome scan to observe the approach to homozygosity after three generations of selfing. Many unfruitful a...

Abstract Theory predicts that the ability of selection and recombination to purge mutation load is enhanced if against deleterious genetic variants operates more strongly in males than females. However, direct empirical support for this tenet limited, part because traditional quantitative approaches allow dominance intermediate-frequency polymorphisms obscure effects many rare partially recessi...

Captive breeding of endangered species often aims at preserving genetic diversity and to avoid the harmful effects of inbreeding. However, deleterious alleles causing inbreeding depression can be purged when inbreeding persists over several generations. Despite its great importance both for evolutionary biology and for captive breeding programmes, few studies have addressed whether and to which...

Whether to develop inbred cultivars or F1 hybrids is a dilemma faced by many rice (Oryza sativa L.) breeders. This could be partially answered if one could select superior recombinant inbred lines with an equal yielding ability and good quality traits from commercial F1 hybrids. Thus, it was attempted in this study to select superior inbred lines from 2 commercial F1 hybrids after application o...

Disease-mediated inbreeding depression is a potential cost of living in groups with kin, but its general magnitude in wild populations is unclear. We examined the relationships between inbreeding, survival and disease for 312 offspring, produced by 35 parental pairs, in a large, open population of cooperatively breeding American crows (Corvus brachyrhynchos). Genetic analyses of parentage, pare...

The identification of genes selected during and after plant domestication is an important research topic to enhance knowledge on adaptative evolution. Adaptation to different climates was a key factor in the spread of domesticated crops. We conducted a study to identify genes responsible for these adaptations in pearl millet and developed an association framework to identify genetic variations ...
