Exploitation of flow cytometry for plant breeding

In this review, the different applications of flow cytometry in plant breeding are highlighted. Four main breeding related purposes can be distinguished for flow cytometry: (i) Characterisation of available plant material, including screening of possible parent plants for breeding programs as well as evaluation of population biodiversity; (ii) Offspring screening after interspecific, interploidy or aberrant crosses; (iii) Ploidy level determination after haploidization and polyploidization treatments and (iv) Particle sorting, that allows separation of plant cells based on morphological or fluorescent characteristics. An overview and discussion of these various applications indicates that flow cytometry is a relatively quick, cheap and reliable tool for many breeding related objectives.
