Many investigators have used deferent methods for ploidy determination in sugar beet. These methods include measurements of leaf stomatal size (length and diameter), stomatal density, chloroplast number in stomatal guard cells, pollen size and somatic chromosome counting. All these methods were conducted among a diploid population, and its equivalent triploid and tetraploidpopulation UR - http://nile.enal.sci.eg/EALE/2011/EJPB/1511/2/si/227.pdf ER -
