Abstract
This work was carried out at Shandweel Experimental Station, Sohag Governrate during the period from 1995 to 1998 to compare of Shandweel single center progenies with Shandweel-1, Giza 6 Mohassan and Giza 20 for some bulb characteristics. The mean results could be summarized as followed :
1- Percentages of single center bulbs, internal and external doubles, total and culls yield, average bulb weight, percentage of internal doubling at the end of the storage period 6 months were significantly decreased in the progenies of the parent bulbs with single growing point compared with local Egyptian cultivars .
2- Percentages of single growing point for freshly harvested bulbs and single growing point remained as such though at the end of storage period which gave the highest significant increase with progeny of single growing point bulbs.
3- Percentage of single center bulbs was significantly increased with progeny of internal doubles bulbs of the freshly harvested bulbs, while, it gave the highest value with progeny of single center bulbs at the end of the storage period in comprasion with the Shandweel-1, Giza 6 Mohassan and Giza 20 Egyptian cultivars .
4- Total onion yield markedly improve using the Giza 20 ranked by Shandweel 1, Giza 6 Mohassan, compared with the rest of Shandweel S. C. progeny .
