SELECTION OF COLD TOLERANT HIGHLY PRODUCTIVE CORN GENOTYPES USING COLD TEST METHOD
Abstract
108 corn inbred lines were tested in laboratory and field conditions; 7 lines which had high level of cold tolerance were selected. Positive correlation on an average level was revealed between germination, seedling length and yield, average for 2 years – +0.58. Positive correlation on a high level was revealed between the radicle length and yield +0.79. Inbred lines FV 243, UCH 37, HLG 1238, Co 255, Ak 135 and HLG 1203 were recommended for using as sources of cold tolerance.
