| Abstract | ||||
| Fourteen Varieties of sugar cane were chosen from the field of breeding programme in Sabahia Research Station at Alexandria during 2002 to 2005 seasons to study the effect of drowning on the flowering and seed setting of these varieties. Each variety was planted in two ridges. The length of ridge was 5 meters and the distance between the ridges was 125 cm. The rate of nitrogen fertilization was 100 Kg. It was added in three doses. It was after 75, 90 and 120 days from planting date. The rate of doses was equal. Irrigation was every 15 days with the exception of July and August. It was drowned at height 35 cm. It were covered the first and second Internodes. Drainage was every 3 days, and drowning again in the fourth day. All the other cultural practices were conducted for every two ridges in the similar manner whenever possible. The results obtained were as follows: The varieties were differed within and between for flowering dates, flowering percentage, seed setting, flowering duration and seedlings number. The seed setting varieties were differed between, while some varieties were seed setting and another were not seed setting. The seed setting were in the first ratoon only, while the plant crop and second ratoon the crossing were not succeeded. The seedlings number which were obtained were varied from one variety to another. Also some varieties did not enable to obtain the seedlings like the prior varieties. | ||||
