001) observed between heading date in nonvernalized and vernalized plants.
As was the case for heading time, some loci showed relatively small, insignificant effects in both treatments, but the effects had opposite sign in vernalized compared with nonvernalized plants, contributing to significant vernalization responses.
However, their effects on plant height were significant only in nonvernalized plants because of greater error variance in vernalized plants.
In sum, 10 vernalization-sensitive regions were associated with shorter plant height in vernalized plants, while only five were in nonvernalized plants.
A region on LG 24 was associated with heading date in nonvernalized plants and with heading date vernalization response, while a region on LG 17 was associated with heading date in vernalized plants (Table 2).
