The Post-fertilization Reproductive Barriers and Overcoming Methods of Horticultural Crops Distant Hybridization
The research progress of distant hybridization in the field of plants breeding in recent years was re -viewed comprehensively .The characteristics and mechanisms of post-fertilization barriers were analyzed on the view of embryo abortion and hybrid sterility .Meanwhile ,the effective methods to overcome these barriers were mainly re-viewed,including embryo rescue(Ovary,ovule and embryo culture) to prohibit its abortion,doubling chromosomes to restore its fertility and other methods such as chemical treating and back-crossing.At last,the future research em-phasis in this field was suggested as revealing the molecular mechanism of embryo abortion in distant hybridization by using the proteomics combined with molecular physiological methods .
