Use of haploids in crop improvement
Since 1921, when Bergner discovered haploid plants in Datura stamonium, scientists have developed many techniques for inducing haploidy. Induction methods in vitro include anther (pollen) culture, unpollinated ovary culture, and chromosome elimination, of which anther culture is the simplest and most efficient. This technique has been refined and its use in fundamental and applied genetics and in crop improvement is extensive. To increase the induction frequency of green pollen plants, various factors influencing anther culture were investigated. Genetic and cytogenetic theories of wheat, maize, and rice pollen plants were also examined. Theses include plant-regenerating ability, genetic stability and variability of pollen plants, and plant-level gamete analysis. Chinese scientists have extensively used anther culture in plant breeding: many new varieties of rice, wheat, and maize inbred lines of pollen plants have been released
