Critical mutation rate has an exponential dependence on population size in haploid and diploid populations [PDF]
, 2013 Understanding the effect of population size on the key parameters of evolution is particularly important for populations nearing extinction. There are evolutionary pressures to evolve sequences that are both fit and robust.

Interspecific somatic hybrids between Solanum bulbocastanum and S. tuberosum and their haploidization for potato breeding. [PDF]
, 2012 Protoplast fusion between incongruent Solanum bulbocastanum and S. tuberosum haploids was accomplished to produce hybrids combining elite traits from both parents. We identified 11 somatic hybrids out of 42 regenerants analyzed through ISSR markers. Some

Aneuploidy among androgenic progeny of hexaploid triticale (XTriticosecale Wittmack). [PDF]
, 2010 Doubled haploids are an established tool in plant breeding and research. Of several methods for their production, androgenesis is technically simple and can efficiently produce substantial numbers of lines.

Genetic variability of anther donor versus spontaneous doubled haploid descendents and colchicine induced doubled haploid sweet pepper (Capsicum annuum L.) lines [PDF]
, 2001 Haploid (n) and doubled haploid (DH) plants were developed in anther culture of sweet pepper (Capsicum annuum L.). Regenerants were analyzed by flow cytometry for haploid (n = 12) and spontaneous doubled haploid (2n = 24) genomes.

Recombining your way out of trouble: the genetic architecture of hybrid fitness under environmental stress [PDF]
, 2020 Hybridization between species is a fundamental evolutionary force that can both promote and delay adaptation. There is a deficit in our understanding of the genetic basis of hybrid fitness, especially in non-domesticated organisms.

Catastrophic chromosomal restructuring during genome elimination in plants. [PDF]
, 2015 Genome instability is associated with mitotic errors and cancer. This phenomenon can lead to deleterious rearrangements, but also genetic novelty, and many questions regarding its genesis, fate and evolutionary role remain unanswered.

Agronomy, 2020 Doubled haploids have played a major role in cucurbit breeding for the past four decades. In situ parthenogenesis via irradiated pollen is the preferred technique to obtain haploid plantlets whose chromosomes are then doubled in Cucurbitaceae, such as ...

Diploidization of cucumber (Cucumis sativus L.) haploids by colchicine treatment
Acta Societatis Botanicorum Poloniae, 2014 Haploid cucumber plants are totally infertile and do not undergo spontaneous diploidization. The use of haploids depends on the possibility of doubling the chromosome number and the obtaining of stable doubled haploids (DH).
