Eight selected soybean genotypes were grown in ambient and extended photoperiod (17 h). Genotypes showed variation in photosensitivity in terms of days to flower and days to maturity. Photo-insensitive genotypes did not exhibit significant changes in fatty acids under extended photoperiod. However, four soybean genotypes, which exhibited photosensitivity both in terms of days to flower and days to maturity, exhibited an increase in oleic acid content and decrease in linolenic acid content. Therefore, photosensitivity in terms of days to flowering appeared to influence the fatty acid composition of soybean.
