A New Waxy Corn Hybrid Cultivar, “Chalok 4” with Good Eating Quality and High Yield

Abstract

Zea mays L.) developed by the maize breeding team at the NationalInstitute of Crop Science (NICS), RDA in 2004. This hybrid, which has white kernels, a good eating quality and high yield of earweight, was produced by crossing two inbred lines, KW33 and KW35. KW3 is the sed parent and KW35 is the polen parent ofrthan that of a check hybrid, Chalok 1. It is moderate resistant to Biporalis maydis (Southern leaf blight) and resistant to Blackstreaked dwarf virus. Lodging resistance of Chalok 4 was intermediate. The yields of Chalok 4 in fresh ear weight were 28%,welldue to good match during crossing betwen seed and polen parents. It is adaptable to the whole country except Jeju island.
