, the first approaches were conducted to produce doubled haploids in apple by in vitro anther culture ( Nakayama et al., 1972 ). Since then, various homozygous genotypes induction methods such as in vitro anther culture and in situ parthenogenesis in
male sterility in plants has always been a hot spot in the field of botany. Usually, in research on male sterility, cell biology studies on aborted anther development are indispensable and are the first studies conducted, as these studies can reveal the
The anthers of angiosperms are complex male sex organs, and their development is a precisely regulated biological process ( Pearce et al., 2015 ). During anther development, various structural and physiological changes occur, and these changes
reproductive organ of angiosperms. The development of anthers, the parts of the stamen where pollen is produced, is a delicate and complex process that includes the formation of the anther wall tissue (with a protective function) and pollen (with a reproductive
tweezers, and the number of anthers per flower was counted. To collect pollen, the clusters were rubbed through a sieve (Standard Test Sieve, No. 10, pore size = 2 mm, Fisher Sci., Pittsburgh, PA) to remove the calyptras and anthers. Anthers were then
Abstract
Strawberry plants were regenerated by anther culture from 4 different octoploid cultivars of Fragaria × ananassa. All plants possessed the octoploid chromosome number. Evidence is given that the plants may have originated from gametic tissue. Four different nutrient media were tested and Gresshoff and Doy Number 1 medium gave best results.
. Gynogenesis (ovule and ovarium culture), parthenogenesis (pollination with irradiated pollen), and androgenesis (anther and microspore culture) are commonly used to obtain haploid plants via tissue culture. The success of these methods varies according to the
