Purple colored corn has significantly higher anthocyanin concentration than uncolored corn. The demand of purple corn is increasing due to being more beneficial to health compared to yellow corn. There is no any registered variety, genetic pool and breeding program to meet this demand in Turkey. The objectives of this study were to (i) develop purple sweet corn inbred lines, (ii) morphologically define the developed lines and (iii) determine consumer preference on purple sweet corn. Standard sweet corn lines (su) and a purple waxy corn as a color donor that provided from Thailand were used in this study. The study was carried out in Antalya Turkey under field and greenhouse conditions during the consequent of 2017-2021 years. The sweet and the purple donor lines were crossed and then selfed according to the pedigree breeding procedure to develop lines varied for purple and sweetness characters. Developed lines were characterized according to morphological traits and divided into totally seven clusters. Twenty lines were finally selected based on agronomic characteristics under investigation among 118 lines. The results showed that developed purple sweet corn lines had higher anthocyanin (26.09 mg/L), antioxidant capacity (147.50 IC50/DPPH) and phenolic compounds (1014.7 mg Gallic Acid Equivalent/kg) than yellow sweet lines. According to the panel test results, purple sweet corn had higher scale of appearance and purchase request (8.09 and 7.68) than yellow ones (7.60, 7.49) respectively. This is first report on development of purple sweet corn lines in Turkey.
