Scientia Horticulturae, 1981
Abstract Anthers of 2 tetraploid Rosa species (4 n =28) were plated on selected basis media, supplemented with various amounts of auxins and kinetin, at different bud stages and using various light conditions. Among the media tested, MS medium with 2.0 mg/l IAA and 0.4 mg/l K was generally the best for anther culture of R.

Oaks (Quercus spp.) are widely distributed trees of temperate regions, and are of major importance in forestry. Most species are used for wood production, although there are a few interesting peculiarities, such as cork production from the cork oak.

Oat (Avena sativa L.) Anther Culture
2021Production of doubled haploids (DHs) by androgenesis is a promising and convenient alternative to traditionally used breeding techniques. Low response of anther culture and strong genotype dependency in the development of embryo-like structures (ELS) was reported for oat (Avena sativa L.). Total homozygosity has been reached in one generation.

The present long-term tissue culture programme aims at directing double haploid (DH) production of triticale towards responsive genotypes and at the same time allowing the practical use of anther culture in current breeding programmes. It is hoped that this can be achieved without limiting plant breeders to a few selected crosses.

The following procedure for large-scale production of doubled haploids (DH) in wheat at Svalof Weibull AB (SW) is based on protocols developed in Sven Bode Andersen’s laboratory in Copenhagen (Andersen et al., 1987; Tuvesson et al.,1989). Since then the tissue culture programmes were rationalised to a few steps in order to speed up DH production and ...

The production of doubled haploid (DH) barley (Hordeum vulgare L.) plants has proven to be a highly valuable tool for plant breeding, allowing the release of a high number of new cultivars (Devaux et al., 1996). Doubled haploids have also been fundamental for genetic analysis, linkage maps production and QTL analysis in barley.

Microspore development in cultured maize anthers
Plant Cell Reports, 1988The present study follows in vivo and in vitro microspore development utilizing an anther culture-responsive maize genotype (Pa91×FR16) and a DNA-specific fluorescent dye (mithramycin). Cultured anthers were sampled at various times and scored for abnormal microspore divisions, multicellular masses, and embryo-like structures. The frequency of abnormal

Anther culture of some perennial triticeae
Plant Cell Reports, 1988Three field grown Agropyron spp. (crested wheatgrasses) and two Thinopyrum spp. (intermediate and tall wheatgrasses) were evaluated for anther culture response. Hormonally modified potato extract and 85D12 media induced pollen embryogenesis. Modified Murashige and Skoog media were tested for their effects on callus proliferation and plantlet ...

The production of doubled haploids through androgenesis represents a modern tool for the improvement of cultivated species enabling plant breeders to produce homozygous lines in a few months. In barley and other cereals, the use of androgenesis has generated a number of cultivars currently available and cultivated in many countries.

Methodical improvements in rye anther culture
Plant Cell Reports, 1991The crucial problem in anther culture of rye (Secale cereale L.) is the very low regeneration capacity. Our study was conducted to overcome this restriction. The plant material used included a doubled haploid line (DH), two single crosses between DH Unes, and a tetraploid Secale cereale L. population.
