Alien chromosome fragments conditioning resistance to beet cyst nematode in diploid descendants from monosomic additions of Beta procumbens to B. vulgaris



Alien chromosome fragments conditioning resistance to beet cyst nematode in diploid descendants from monosomic additions of Beta procumbens to B. vulgaris



Canadian Journal of Genetics and Cytology 28(3): 439-443



A monosomic addition plant of B. vulgaris, containing an extra chromosome of B. procumbens with a gene for resistance to Heterodera schachtii gave rise to a diploid descendant with an additional chromosome fragment. This fragment was found to bear the gene for resistance. A study of its morphology and behaviour made it likely that it represents the short arm of the alien chromosome and may have originated by centric fission of the single addition chromosome at anaphase I or II.
