8. sb continues to be abnormal. Many sb plants last summer had stiff, very narrow leaves. In some cases these consisted of little but midrib. Plants with such leaves were usually sterile. Pollen was obtained from two for crosses. Ratios in sb crosses were again atypical. One F2 contained 177N:34sb (5:1). Several back-cross cultures contained:
| Culture | Sb | sb |
| 1 | 40 | 30 |
| 2 | 46 | 36 |
| 3 | 50 | 31 |
| 4 | 53 | 40 |
| 5 | 45 | 46 |
| Total | 234 | 173 |
