Monogenic Resistance to Verticillium Wilt in Sunflowers1
- G. N. Fick and
- D. E. Zimmer2
Sunflower (Helianthus annuus L.) inbred lines ‘HA 89,’ ‘HA 124,’ and ‘P-21 VRI’ and their Fl hybrids were highly resistant to Verticillium wilt under field conditions. Segregation ratios from testcross and F2 populations indicated the presence of a single dominant gene for resistance in each line. Intercrosses among the resistant lines showed that the same gene conditioned resistance in the three lines.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
