Recurrent selection schemes designed to improve the cross between two populations are known as reciprocal recurrent selection (RRS). At the University of Wisconsin, J.H. Lonnquist initiated the W577 full-sib RRS program in the early 1970s. W577 is a double cross hybrid [(W64A x A295)(Oh43 x W374R)]. Six cydes of the W577 RRS program have been completed, starting with the F2 of each single parental hybrid as the origina1 A (W64A x A295) and B (Oh43 x W374R) populations. Selection was based on increased grain yield and decreased grain moisture. Direct and indirect responses of selection and estimated inbreeding depression for several agronomic traits were examined.
