A Waxy Corn Hybrid with Early Maturity and High Yield, ＂Sinchalok＂

다국어 초록 (Multilingual Abstract)

Sinchalok, a new waxy corn hybrid was developed from the cross between two inbred lines KW36 as a seed parent and KW1 as a pollen parent at the National Crop Experiment Station, RDA in 2001. Sinchalok was 66 days in days to silking and early maturity hybrid to be similar to Chalok1. Sinchalok is a short-stature hybrid, of which plant height was 185cm. Sinchalok was similar to Chalok1 as 16.8cm in ear length, but larger in ear diameter. Sinchalok was relatively resistant to Biporalis maydis (Southern leaf blight) and maize dwarf mosaic virus. Lodging resistance of Sinchalok was intermediate, but more resistant than that of Chalok1. Sinchalok was compared with Chalok1 as the designation of Suwon32 at four sites for three years from 1999 to 2001. In these tests, the fresh ear weight of Sinchalok was 10.36 ton/ha and 19% higher than that of Chalok1. Sinchalok is adaptable to all over the country including early-planting culture region of the southern part of Korea.
