CO450 corn inbred line

Reid, L.M., Zhu, X., Voloaca, C., Wu, J., Woldemariam, T., Martin, R.A., Beres, B.L. (2014). CO450 corn inbred line, 94(1), 161-167.


CO450 is a short-season early-maturing (average 71 d to flowering) corn (Zea mays L.) inbred line with excellent combining ability and superior resistance to eyespot (Aureobasidium zeae). This is the first inbred to be released from AAFC's eyespot resistance breeding program. CO450 also has moderate resistance to common rust, intermediate resistance to common smut and both fusarium and anthracnose stalk rot. Excellent hybrid yields and performance data were achieved when CO450 was crossed with stiff stalk inbreds such as MBS1130 and an Iodent inbred, MBS8148. CO450 also exhibited good performance at sites with 2400 CHU or less in combination with a very early inbred, CL30.
