Selection and breeding of corn to enhance associative bacterial nitrogen fixation
Conference

OSTI ID:6461613
We have increased, through screening and breeding, the ability of corn (maize, Zea mays L.) to support bacterial nitrogen fixation in or on corn roots. Isotopic N fixed from /sup 15/N/sub 2/ was found on the roots. Even though the nitrogen-fixing association depends on germ plasm from tropical corn, the activity can be bred into corn currently used in midwestern United States agriculture.
