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.

Anther culture of papaya (Carica papaya L.)
Plant Cell Reports, 1985Papaya (Carica papaya L.) anther containing microspores in tetrad to early-binucleate stages were successfully cultured on 1/2 strength MS salts and vitamins with full strength Na-Fe-EDTA supplemented with 2 mg/l NAA, 1 mg/l BA and 6% sucrose for callus initiation and formation.

It is becoming increasingly evident that endogenous ethylene can have large and diverse effects on growth and development in a wide range of plant tissue culture systems [2]. Anther culture in which haploid plants are regenerated from immature microspores is important because it allows the rapid production of homozygous lines for breeding and genetic ...

The maize pollen grain represents the beginning of a short-lived gametophytic phase during which the two sperm are delivered to the embryo sac prior to fertilization. Although this stage of the life cycle normally consists of only a few cell divisions, under certain experimental conditions, gametophytes can be induced to undergo an altered development,

Anther culture of Solanum genotypes
Plant Cell, Tissue and Organ Culture, 1987Anther culture response was examined in five Solanum genotypes. Large genotypic differences exist in response to culture and liquid culture media were found to be superior to agar solidified media systems. Pre-treatment effects on embryoid induction were also investigated and two of the genotypes displayed differential response to temperature stress ...
