Abbreviations: ASI, anthesis-silking interval; ERH, ear height; NS, not significant; PEH, plant height above ear; PLH, plant height; REML, restricted maximum likelihood; SPL, spike length; TSW, tassel weight; *0.1<P<0.01; ***0.001<P<0.0001.

^aOR: observed response to selection; : phenotypic s.d.; : restricted maximum likelihood estimated genotypic correlation; CR: correlated response to selection.

^bP-value based on Wald test; H_O: γ>0.

^cP-value based on t-test with 1 degree of freedom and s.d. equal to that of OR; H_O:OR >PR_.
