  • To get abundant germplasm for developing new waxy corn varieties, pericarp thickness was measured and other factors were evaluated with a total of 142 Korean local waxy corn lines collected from various parts of Busan City and Gyungnam Province. The average pericarp thickness of Korean local waxy corn lines collected was $40.61{\mu}m$ and the rate of thin pericarp under $50{\mu}m$ was 70.4%. The pericarp thickness compared by the regions collected showed non significant difference, but which compared by the ear row number per ear showed significant difference $(MS=597.52^*)$. Correlation between pericarp thickness and row numbers per ear was low (-0.93).

  • This study was carried out to identity the major characteristics of inbred lines and to develop early waxy colored hybrid at the Maize Genetics and Breeding Lab. in Chungnam National University. The eight colored waxy maize were planted on April 27, 2007 under Randomized Completely Block (RCB) Design with three replications. Stem height of IK1/H26-2 and Heunchal lines in this experiment were high as 196cm and 186cm compared to control as 156cm, respectively, while ear height of Local-2 and IK/LE were lower than that of check and ear diameter of IK/H26-1, IK/H26-2 and Local-2 were 10.3mm, 17.7mm and 18mm compared to control (21mm), respectively. Days to tasseling of Local-1, Local-2, and IK/LE lines were earlier than check. As a result of this experiment, the developed inbred lines were regard as useful germplasm for early hybrid development.

  • Ears collected from 500 regions were phenotypically observed for their ear and kernel characters. Characters studied included ear shape, kernel color, kernel density, ear row number, starch quality, pop corn and waxy corn, ear length, ear diameter, kernel length, kernel width, kernel weight, ear weight, and 100 kernel weight. The Korean local corn collected were mostly flint type and were very diverse in all the characters studied. The collected local corn would be very promising for providing good germplasm for corn breeding in the future.
