Doubled haploid sugar beet: an integrated view of factors influencing the processes of gynogenesis and chromosome doubling [Full subscriber]

Abstract Haploid and doubled haploid plant production through unpollinated ovule culture, with diverse benefits and applications, is considered among the effective and advantageous breeding methods for sugar beet (Beta vulgaris L.). Sugar beet is not responsive to androgenesis that is widely used for most plant species. It is a recalcitrant plant in vitro due to the very low spontaneous chromosome doubling and low gynogenesis rate. Thus, steadily increasing gynogenesis efficiency has always been an important target. Given the lack of papers focusing on gynogenesis in sugar beet, this review covers haploid and doubled haploid production through ovule culture of unfertilized flowers…
