Description:	Title: Use of isolated microspore culture as a tool for obtaining Genetic Modified Organisms and for speeding up wheat and barley genetic breeding programs Authors: Sandra Maria Mansur Scagliusi, Edson Iorczeski, Sandra Patussi Brammer, Ana Lídia Bonato, Luciano Consoli, Antonio Nhani Junior, Euclydes Minella, Pedro Scheeren, Márcio Só e Silva and Eduardo Caierão Unidade: Embrapa Trigo The integration between plant breeding and biotech strategies, has accelerated the process of obtaining complete homozygosity, resulting in a significant progress in the plant selection system. Through the production of in vitro double haploid plants, totally pure lines are obtained in one generation. At Embrapa Trigo, wheat immature embryos and barley anther cultures have been broadly used in the genetic breeding programs of winter cereals. However, the low number of produced plants has encouraged many researchers to improve the process. Among the different technologies to produce doubled haploids, isolated microspore culture is by far the most efficient, resulting in a larger number of fertile plants per spike. Microspores can be used to improve selection efficiency, estimate genetic variance and facilitate genetic transformation and mutation studies. Optimization of the technique has provided over the years, in vitro selection of genotypes resistant/tolerant to biotic/abiotic stresses, accelerating the whole process even more. Thanks to many decades of research, a better understanding of androgenesis and recent technology innovations, microspore culture has become a fast track to new varieties, assuming an important step in the plant breeding programs. At Embrapa Trigo, the establishment of the technique will be accomplished in the next following years, as it already is part of the wheat and barley breeding programs.
