Plants, 2022 This paper reviews the progress and the way ahead in diploid F1 hybrid potato breeding by comparisons with expectations from the theory of inbreeding and crossbreeding, and experiences from other diploid outbreeding crops.

Linkage disequilibrium and recombination rate estimates in the self-incompatibility region of Arabidopsis lyrata [PDF]
, 2007 Genetic diversity is unusually high at loci in the S-locus region of the self-incompatible species of the flowering plant, Arabidopsis lyrata, not just in the S loci themselves, but also at two nearby loci.

GENETIC ARCHITECTURE OF INBREEDING DEPRESSION AND THE MAINTENANCE OF GAMETOPHYTIC SELF‐INCOMPATIBILITY [PDF]
Evolution, 2014 Gametophytic self-incompatibility (GSI) is a widespread genetic system, which enables hermaphroditic plants to avoid self-fertilization and mating with close relatives. Inbreeding depression is thought to be the major force maintaining SI; however, inbreeding depression is a dynamical variable that depends in particular on the mating system.

When gametophytic self-incompatibility meets gynodioecy
Genetics Research, 2008 SummaryThe occurrence of gynodioecy among angiosperms appears to be associated with self-compatibility. We use individual-based simulations to investigate the conditions for breakdown of a gametophytic self-incompatibility system in gynodioecious populations and make a comparison with hermaphroditic populations where the conditions are well known.

Detection of Self Incompatibility Genotypes in Prunus africana: Characterization, Evolution and Spatial Analysis. [PDF]
PLoS ONE, 2016 In flowering plants, self-incompatibility is an effective genetic mechanism that prevents self-fertilization. Most Prunus tree species exhibit a homomorphic gametophytic self-incompatibility (GSI) system, in which the pollen phenotype is encoded by its ...

The Indian Journal of Agricultural Sciences, 2016 Gametophytic self-incompatibility, governed by the S-locus in apple (Malus spp.) plays a vital role for pollination and fruit set. The identification and cloning of RNases has enabled the use of molecular techniques to characterize Sgenotypes in apple ...

Gametophytic self-incompatibility re-examined: a reply [PDF]
Heredity, 1985 In principle, as has long been known, there are two ways by which the stigmas or styles of the flowers of self-incompatible species could discriminate between incompatible and compatible pollen, for either the growth of the former would be inhibited (the oppositional hypothesis) or that of the latter stimulated (the complementary hypothesis).

, 2008 Background Solanum carolinense (horsenettle) is a highly successful weed with a gametophytic self-incompatibility (SI) system. Previous studies reveal that the strength of SI in S. carolinense is a plastic trait, associated with particular S-alleles. The

, 2009 In previous studies, we have investigated the strength of self-incompatibility (SI) in Solanum carolinense, a highly successful weed with a fully functional SI system that inhabits early successional and other disturbed habitats.

American Journal of Botany, 2023 AbstractPremiseSeed production is frequently limited by the receipt of insufficient or low‐quality pollen, collectively termed “pollen limitation” (PL). In taxa with gametophytic self‐incompatibility (GSI), incompatible pollen can germinate on stigmas but pollen tubes are arrested in styles.
