CO477, CO478, CO479, and CO480 inbred lines

Abstract

CO477, CO478, CO479, and CO480 are mid- to late-season [75–81 d to flowering, crop heat units (CHU) = 1720–1855] corn (Zea mays L.) inbred lines with high stalk sugar levels. The level of sugar in the stalks are very high especially when grown as inbred lines. On average, the inbred lines yield three times more sugar than their testcrosses. These inbred lines are the first to be developed and released for biofuel production, from the corn breeding program of Agriculture and Agri-Food Canada. Additionally, these inbred lines can be used for sugar and (or) silage production. They have moderate to intermediate resistance to common rust, eyespot, northern corn leaf blight and fusarium stalk rot but are susceptible to gibberella ear rot.
