The onion cultivar “Texas Early Grano” is very popular in Sudan as it is consumed as a salad vegetable. Attempts to produce seeds of this cultivar locally succeed under Gezira condition by using vernalization and GA. Therefore, the objective of this study was to evaluate onion cultivar “Texas Early Grano” planted from the seeds, which were produced locally, with those planted from the imported seeds which produced by two seed companies (A and B) for growth parameters, bulb quality parameters and during winter season of 2010/11. Results indicated that there were no significant differences in number of leaves and bulbing ratio index, but there were significant differences in plant height. The tallest plants (68 cm) were obtained from seeds of A Company followed by those from local seeds and lastly plants grown from seeds of B Company (66.1 and 62.8 cm, respectively). Bulbs produced from local seeds obtained the highest bulb weight (213.6 gm), the highest percentage of large bulbs (43.0%) and the highest percentage of globe bulb shape (64.1%). However, it obtained average values of doubling percentage (18.2%), thick neck percentage (15.9%), percentage of small bulb size (24.8%), medium bulb size (32.2%) and percentage of flat bulb shape (12.3%) compared with bulbs produced from the two seed companies. The highest yield was obtained by bulbs produced from seeds from A Company (39.8 ton/ha).
