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.

The Botanical Review, 2010
Androgenesis can be defined as the set of biological processes leading to an individual genetically coming exclusively from a male nucleus. Androgenesis was traditionally considered as the spontaneous, in vivo development of a male-derived haploid embryo from a fertilized egg where the female nucleus is eliminated.

Summary The techniques of androgenesis adapted to pearl millet, Pennisetum typhoides, described here have led to the obtention of embryoids and calluses from all the genotypes used. Plants have been regenerated from 23 D2B1 and from F1 hybrid Massue ♀ × Liqui ♂ microspore cultures.

Plant Cell Reports, 1998
The influence on androgenesis of donor plant growth conditions, anther size and developmental stage of the microspore, medium composition and different anther treatments prior to culture was investigated in L. esculentum Mill. cv Roma and its hybrids. Growth conditions of donor plants affected the induction of tomato androgenesis. Anthers isolated from

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.

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 ...

Androgenesis in Citrus aurantifolia (Christm.) swingle
Planta, 1985Embryoids were differentiated from anthers of C. aurantifolia which were first floated on a modified Murashige and Skoog's liquid medium supplemented with 0.5 mg/l N(6)-benzylaminopurine and 1 mg/l indole-3-acetic acid for 20-30 d, followed by 30 d culture in semisolid Schenk and Hildebrandt's medium having the same growth hormones.

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 ...

Experimental androgenesis in plants—A review
Proceedings / Indian Academy of Sciences, 1977This presents the review of seventynine species and varieties of angiosperms in which androgenesis has been induced. The culture practices, probable factors (physiological, bio-chemical and cytogenetical) involved and the applied aspects of andromorphogenesis are analysed.

Role of the Generative Cell in Androgenesis in Henbane
Science, 1976When anthers of henbane containing uninucleate pollen grains were cultured, a large number of embryoids originated exclusively from the division of the generative cell. In a small proportion of pollen grains, both generative and vegetative cells contributed to embryoid formation.
