Reverse Breeding: A New Method for Crop Improvement

  1. Puthem Victoria Devi

Abstract

Reverse breeding makes use of genetic modification to facilitate breeding of F1 hybrids by suppression of meiotic recombination which starts with an elite heterozygous line and aims at the generation of homozygous parental lines and later original heterozygous line isconstituted. The technique allows breeders to produce a hybrid in much shorter time than the conventional methods. The objectives of reverse breeding are to provide alternative method for providing homozygous parental lines, more flexible in combining desirable parental lines for production of hybrids and allows generation of chromosome substitution line that will facilitate breeding to study on an individual chromosome level.
