Abstract: Sweet corn is planted for using as fresh and processing at local market. Two field experiments were
investigated at Agricultural Research Center (ARC) Station during the two seasons (2016 and 2017). In the first
experiment interested on evaluation the total soluble solids (TSS) and total sugar (TS) content in 17 sweet corn hybrids.
In the second experiment, the highest three crosses value of (TSS and total sugars) were selected and in the second
season were grown under three planting dates (D1: March 21st, D2: May, 23rd and D3: Aug., 22nd) to evaluate the effect
of the planting date on sweet corn growth, yield and its quality parameters in fresh and processed product. Quality
parameters for the first season (TSS and TS content) showed significant differences among 17 hybrids. The hybrids
named Gz3B×Gz15, Gz3B×Gz20 and Gz20×Gz10 had the highest values of TSS and TS (16.06, 17.19 and 17.43%)
and (5.46, 5.76 and 6.84%), respectively. In the second experiment, the grain yield, ear length and diameter, showed the
highest values recorded at Aug 22nd planting date. The highest values of TSS and TS were observed at Aug 22nd after 20
days from pollination for the three selected sweet corn hybrids, which a decrease at the 3rd harvest date after 26 days
from pollination. A reduction in lightness values was observed as the harvest date increased. Total carotenoids content
increased by increasing the harvest date and the highest content found at the third planting date (Aug 22nd) for
Gz3B×Gz20 and Gz20×Gz10 hybrids. Cooking of the Gz3B×Gz20 and Gz20×Gz10 hybrids showed higher sensory
characteristics than corresponding Gz3B×Gz15 hybrid. No significant differences between two hybrids (Gz3B×Gz20
and Gz20×Gz10) in overall acceptability during storage for 9 months at -18?C±2. The highest decrease in total sugars
content during storage was found in the Gz3b×Gz15 hybrid.
