Use of Self-fertility in the Improvement of Bromus inermis and Phleum pratense1
- P. N. Drolsom and
- E. L. Nielsen2
Experimental populations of Bromus inermis Leyss. and of Phleum pratense L. have been formed either with nearly self-sterile plants or with plants possessing modest levels of self-fertility. Both groups within a species originated from the same population and were submitted to the same selection pressures for agronomic features and disease resistance. Experimental synthetics based upon plants with a modest level of self-fertility have indicated some superiority in disease resistance and a possible yield advantage over combinations of self-sterile plants. Seedset data after mutual- and open-pollination suggest that self-fertile plants form more seed than self-sterile plants.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
