In Vitro Haploid Production—A Fast and Reliable Approach for Crop Improvement

摘要: The haploid derived true homozygous lines are of utmost importance for crop improvement, especially in the case recalcitrant, heterozygous, woody plants. In vitro production methods provide a rapid means achieving homozygosity, by hastening up conventional breeding improvement. Homozygous diploid plants can be produced single generation diploidization raised haploids with application chemical mutagens. techniques like androgenesis and gynogenesis most prolific desirable approaches recent times, which is achieved stimulating either male or female gametophyte. However, frequency getting through predominantly higher than due to large number micropores present within anther as against egg cell ovules. Through this chapter, we have attempted brief overview various factors affecting production, methodologies concerned, confirmation ploidy level regenetants, together research update, current status few economically-important recalcitrant tree species. This chapter will act guide prospective scientists working area intended improve productivity.
