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 ...

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.

The response of anther culture to culture temperature in Triticum aestivum
Theoretical and Applied Genetics, 1983The response of anther culture to culture temperature was studied in detail using many varieties, F1 hybrids and pollen-derived lines of wheat (Triticum aestivum) as materials. The suitable culture temperature for inducing pollen callus (or embryoids) in wheat anther culture ranged from 26 °C to 30 °C, varying with genotypes. But for the great majority

Anther Culture of Potato: Method and Applications
2021Anther culture provides a tool to produce haploid lines from cultivated potato (Solanum tuberosum L.), which has a tetraploid (2n = 4x = 48) genome constitution. Shoot regeneration via direct embryogenesis in anther culture procedure is preferred to produce dihaploid (2n = 2x = 24) potato lines, which can be applied in breeding of potato varieties. The

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.

Pollen dimorphism and anther culture in barley
Planta, 1975A dimorphism is observed in barley (Hordeum vulgare L., cv. Akka) pollen when stained with acetocarmine from the mid-binucleate stage onwards. The majority of grains have staining cytoplasms, while the remainder have cytoplasms which take up little or no stain (NS grains).

Haploids in higher plants have provided the subject of three symposia in recent years (36,78,106) and their use in plant breeding has been covered in a most comprehensive review (97). All four volumes explain in detail that haploids have the great advantage of providing a rapid, and in some species the only, route to complete homozygosity.

In this chapter, the published reports of anther and microspore culture of Petunia will be reviewed in comparison with culture of related Solanaceous genera. The reasons for the type and frequency of microspore development in Petunia will be explored.

Anther Culture and Production of Haploids
1998Haploid plants have the gametophytic number of chromosomes. They can be derived by several different ways. Haploids via twin seedlings can spontaneously occur in nature. Maternal haploids may arise from certain interspecific crosses followed by the elimination of chromosomes from the pollen donor during embryo development.
