Response of Some Quality Traits of Sunflower Seeds and Oil to Different Environments

Abstract

Abstract Five sunflower hybrids and one open‐pollinated variety were sown at two locations in West Germany and at two‐sowings at Giza, Egypt (summer and winter seasons). Cultivars showed different response concerning oil and protein contents as well as fatty acid composition. Highest protein content was observed from Giza in winter season. Cultivars differed significantly with this respect under different environments. However, oil content was not significantly affected by environments X cultivars interaction. Regarding fatty acid composition, palmitic and stearic acids were insignificantly affected. However, highest oleic acid percentage (57.5%) was observed at Giza in summer sowing by Nhy , hybrid, while at Giza in winter sowing the highest value (25.7%) was produced by Semu 209 hybrid. The differences between the two Germany locations were relatively low in range from 14.6–17.6%. Concerning linoleic acid, it showed an opposite trend. Environments X cultivars interaction showed significant influence on total tocopherol content.
