Abstract
|
|
|
Background: Ixeris strigosa is a perennial plant of the Asteraceae family that grows along roadsides and in meadows. Limited breeding and cultivation research has been performed, and there are no cultivars. Therefore, we conducted breeding studies to develop a new cultivar with a high yield and high antioxidant content.
Methods and Results: In 2012, we successfully crossed a ‘Seosanjaerae’ (female parent) and ‘Geumsanjaerae’ (male parent). In 2015, we selected the best lines from the offspring. In 2018, we conducted replicated yield trials (RYT). In 2019, we performed local adaptability tests (LAT). The ‘Soksaewon’ line has beneficial characteristics, including increased plant height, number of leaves, root diameter, and fresh root weight when compared with ‘Seosanjaerae’ (a parental cultivar). The cultivar also exhibited increased total polyphenol, total flavonoid, antioxidant activity, and luteolin7-glucoside. In 2019, the cultivar was successfully grown in three different regions. In all regions, the dried root yield was 1,869 ㎏ per acre, representing a 119% yield increase when compared to ‘Seosanjaerae’.
Conclusions: In 2020, we have developed a new cultivar, ‘Soksewon’ which is high yielding with a high antioxidant content
