520 _aA biparental population of 150 recombinant wheat inbred (RI) lines segregating for reaction to Stagonospora nodorum was developed and tested in the greenhouse and field for levels of resistance. The F 3:4 lines were tested in the greenhouse for incubation period and percent leaf infection 5 and 10 days after initial symptoms of disease. Plants were tested at both the juvenile and adult stages. Adult plants were also tested for percent disease on the spike. The F 3:5 lines were tested in the field over four locations for level of adult leaf and head resistance. Heritability of leaf resistance to S. nodorum was calculated to be 0.56 on an entry means basis and 0.17 on a per plot basis. Heritability of resistance of the spike was calculated to be 0.57 on an entry means basis and 0.20 on a per plot basis. Both heritability estimates are based on field data. Correlations between field data and greenhouse data were generally weak, notably between field data and greenhouse performance of juvenile plants. However, resistance of the spike in the field and the greenhouse were highly correlated (r = 0.74).
