Abstract:

Carotenoid pigments are fat-soluble red-orange colored pigments found in plants. Carotenoids are the precursors of vitamin A
and an essential nutrient for animals including humans. The objective of this study is to select high pigment hybrids by analysis
of carotenoid contents in corn grain so as to increase pigment production. We selected 10 among 100 hybrids and analyzed yield
and carotenoid contents at 2014 in Hongcheon, Republic of Korea. Grain yield is quite different among selected hybrids from 0.7 t
to 0.9 tonne per hectare. We analyzed the 4 carotenoids including α-carotene, β-carotene, lutein and zeaxanthin. α-carotene was not
detected. β-carotene was 0~0.5 mg/100 g, lutein was 0.5~0.8 mg/100 g and zeaxanthin was 0.2~0.4 mg/100 g. In order to develop
varieties and industrialize corn pigments, it is necessary to select inbred lines containing high carotenoids and select parental lines
having good combining ability among selected lines.
