Onion varieties are very specific in their photoperiod and vernalization requirements and therefore vary for yield, yield
related traits and bolting in a specific agro-climate. Therefore, performance of nineteen onion varieties for these traits was
evaluated at Vegetable Research Institute, Faisalabad. The maximum bolting percentage was recorded in Desi Red (46.67%)
that indicates less vernalization requirement of this variety while it was the minimum in Faisal Red and VRIO-6 (13.33%).
The cultivar Phulkara produced larger size bulbs (73.22 mm diameter) as well as highest yield (21.90 t ha-1
) and bulb to neck
diameter ratio (6.75). Similarly, minimum weight loss during curing was observed in Desi Red (4.64%), Pusa Red (4.76%)
and Phulkara (4.83%), indicating higher dry matter contents while maximum weight loss (6%) was recorded in VRIO-6.
Overall results revealed that both Phulkara and Desi Red are excellent for processing while Dark Red for cooking purpose
under agro-climatic conditions of Faisalabad.
