How is the set of RILs generated in this project (the maize NAM population) useful?
The Panzea (Maize Diversity) project has generated a set of 5000 RILs grouped into 25 families. The 25 RIL families were derived from the F2 of crosses between the elite inbred line B73 and 25 other diverse inbred maize lines (a list of the 25 diverse maize inbred parental lines can be obtained here). This set of 5000 RILs, (along with the pre-existing IBM RIL population derived from a cross of B73 and Mo17) comprise an immortalized QTL mapping resource for the maize community.
