Flow cytometric DNA analysis of wheat-rye addition lines
Authors:
Abstract
The nuclear DNA content of the 7 wheat‐rye chromosome addition lines were determined by flow cytometry. The nuclear DNA content of each line was compared to the original wheat parental line. From this information, the amount of DNA per rye chromosome was calculated. The DNA per chromosome ranged from 0.8 picograms (pg) in chromosome 3R to 1.4 pg in chromosome 7R. Flow cytometry was proven to be a rapid and reliable technique for the evaluation of aneuploid plant populations. Flow cytometry has the potential to allow for more rapid screening of aneuploid and euploid cytological stocks than conventional cytogenetic techniques.Keywords
