Interpretive Summary:

Technical Abstract: Transfer of soybean cyst nematode (SCN) to soybean from a wild perennial relative of soybean Glycine tomentella has been reported. Our research objective is to determine SCN resistance levels in all 328 accessions of G. tomentella. In our initial study, 12 accessions representing all four chromosome levels (2n = 38, 40, 78, 80) within G. tomentella were screened for resistance to SCN races 1, 3, and 4. Resistant, susceptible, and intermediate plants were found between and within accessions. Susceptibility appears to be correlated with chromosome number. All 328 accessions will be tested in year 2000. We will begin to study the mode of inheritance of this SCN resistance, and ultimately transfer new sources of resistance to SCN into soybean.
