Waxy corn is commonly eaten fresh in Asian countries including Vietnam. Selection for thinner pericarp is a priority for enhancing tenderness in fresh waxy corn breeding. The research have evaluated 48 of local maize cultivars and inbred lines in order to identify genetic materials that have thinner perricap for the waxy maize breeding with improved quality. The 48 cultivars and inbred lines were evaluated in the field experiment with two replication in 2012 Autumn-Winter season. Kernel pericarp thickness of cultivars and inbed lines (measured by micrometer) ranged between 51.6 to 118.9 um. Six potential lines and cultivars with desirable pericarp thinness are 027, 034, 036, 014, 022 and 035 (027 with 51.6 um). Using SSR markers 28 cultivars and inbred lines were detected to have QTL controlling thinner pericarp traits. Based on phenotypic evaluatione and genetic markers, six cultivars and inbred lines, 014, 022, 027, 047, 036 and 044, possessing desirable agronomic characteristics, thinner pericarp were selected for high quality waxy maize breeding programme in Vietnam.
