Screen at least 1000 more lines derived from soybean by G. tomentella crosses.
Retest some of the lines initially screened with relatively high female indices but still much less than the susceptible check.
Test the G. tomentella parent with additional HG types to determine if the resistance pattern in PI 441001 is different from that observed in any soybean lines.
Continue to produce new lines from additional backcrosses between Dwight and PI 441001.
