HaploidCapsicum through experimental androgenesis
Protoplasma, 1973Haploid embryos and plantlets in yet another solanaceous member viz.,Capsicum annuum L. var.grossum Sendt, have been successfully rearedin vitro through culture of young immature anthers. Exogenous auxin (IAA) was essential for the initiation of cell division in pollen oriented towards a haploid morphogenesis.

The Solanaceae is one of the most important families for global agriculture. Among the different solanaceous species, tobacco (Nicotiana tabacum), potato (Solanum tuberosum), tomato (Solanum lycopersicum), eggplant (Solanum melongena), and pepper (Capsicum annuum) are five crops of outstanding importance worldwide.

Induced androgenesis in rainbow trout
Journal of Experimental Zoology, 1984AbstractAndrogenesis was induced in rainbow trout, Salmo gairdneri, when eggs were irradiated with Co60 gamma‐radiation prior to fertilization. Peak survival of the androgenetic haploids occurred at a radiation dosage of 3 × 104 roentgen (R). The survival of these androgenetic haploid embryos was not significantly lower than that of the gynogenetic ...

Since the beginning of scientific plant breeding, great efforts have been made to speed up the process of hybrid variety production, which normally requires at least six inbreeding generations. Since the successful production of androgenic haploids of Datura by Guha and Maheshwari (1964), and of rice by Niizeki and Oono (1968), great advances have ...

Induced androgenesis in alfalfa (Medicago sativa L.)
Plant Cell Reports, 1995Anthers of 10 alfalfa (Medicago sativa L.) lines were used as initial material for the production of androgenic haploids. More than 30 variants of nutrient media were tested. Twenty five different treatments with low temperatures and gamma rays were tried in order to find optimal conditions for callus induction and organogenesis.The genotype, stage of ...

Detection of Androgenesis-Related Proteins in Maize
1990Dramatic improvements of the androgenetic response in maize (Zea mays L.) have been achieved recently through selection of some highly androgenic genotypes (1,2). However, the utilization of in vitro androgenesis in maize breeding still requires increased responsiveness to anther culture in germplasm with agronomic interest. Clearly, a better knowledge

Androgenesis Conditioned by a Mutation in Maize
Science, 1969A maize embryo having the nuclear constitution of a reduced gametophyte cell is produced in 3 percent of the embryo sacs of inbred strain Wisconsin-23 that carry the mutant indeterminate gametophyte ( ig ). The nucleus of most monoploid sporophytes so derived is paternal.

In vitro androgenesis in apple
2003Most temperate fruit trees are characterized by a long reproductive cycle and juvenile phase (both of several years), a tendency to allogamy and a large tree size. Fruit trees are generally highly heterozygous, outbreeding species, which are propagated asexually. For these reasons, their genetic improvement by conventional methods is time-consuming and
