Characteristics of the foxtail millet(setaria italica L.beauv) local collections in Korea

To obtain basic information on the general characteristics of Korean local collections of foxtail millet, 88 local lines were collected widely throughout the country and investigated some morphological characteristics and studied also some ecological characteristics on the days from planting to heading and maturity by means of planting five times with 20 days interval. Ninty six per cent of collected lines showed green basal colour of culm and remains were purple or greenish purple. Most of collected lines showed cylindrical ear type and some of them were Indian club type, and only 2 lines showed branched type. Some morphological characters showed considerable variation ranging 103 to 162cm in culm length, 10 to 14 in the ratio of length to width of flag leaf, 6 to 10 in the ratio of length to thickness of millet ears, and 52 to 323g in the grain yield per 0.6m², respectively. But there were no close relation of collected lines with regional distribution in the above morphological characters. The days from planting to heading ranged from 72 days to 106 days and most of lines collected from southern part showed middle and late in heading. About 80% of collected lines showed 5 to 7 days in the shortening ratio of the days from planting to heading, and 87% of the lines ranged 7 to 10 days in the shortening ratio of the days from planting to maturity. The variation of shortening ratio of the days from planting to heading and muturity was not large enough to classify the ecotype of collected lines.
