Abstract
The present experimental work was conducted in the Farm of Nubaria Agricultural Research Station for the two successive winter seasons of 2011/2012 and 2012/2013 on onion crop to study the correlation coefficients among the characters of total yield, marketable yield, average bulb weight, days to maturity, plant height, number of leaves per plant, percentage of single bulbs, percentage of double bulbs, percentage of bolters, total soluble solids (TSS %) and storage ability of bulbs. Results showed that correlation coefficients among characters  were positive with days to maturity, plant height, number of leaves per plant, percentage of double bulbs, total soluble solids (TSS %) and storage ability of bulbs in both seasons while the correlation coefficients among characters were negative among total yield with percentage of bolters, marketable yield with storage ability of bulbs, percentage of single bulbs with percentage of bolters and percentage of bolters with total soluble solids (TSS %) in the first season. Also, in the second season, the correlation coefficients among characters were found to be negative among marketable yield with percentage of bolters, average bulb weight with storage ability of bulbs and percentage of single bulbs with both percentage of double bulbs and percentage of bolters.
