Self-fertility in scots pine as a mechanism of resistance to chemical mutagens

Self-fertility in scots pine as a mechanism of resistance to chemical mutagens Experiments on chemical mutagenesis have shown that the seed progeny of self-fertile Scots pine trees (generations M1 and M2) have increased resistance to supermutagens, since the frequency of mitotic pathologies in them has proved to be even lower than in the F1 progeny of self-sterile trees chronically exposed to anthropogenic impact (automobile exhausts). This is evidence that the use of self-fertile forms in selective breeding for general and specific resistance holds much promise. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Ecology Springer Journals

Abstract

Experiments on chemical mutagenesis have shown that the seed progeny of self-fertile Scots pine trees (generations M1 and M2) have increased resistance to supermutagens, since the frequency of mitotic pathologies in them has proved to be even lower than in the F1 progeny of self-sterile trees chronically exposed to anthropogenic impact (automobile exhausts). This is evidence that the use of self-fertile forms in selective breeding for general and specific resistance holds much promise.
