3.3 Relationships of KN/ear, TKW and yield with meteorological
factors
Yield, KN/ear and TKW of Te, Tr, and Te×Tr lines were all significantly
correlated with the daily maximum temperature (DMT), sunshine hours
(SH), and rainfall (RF) (Figure 2). DMT and SH had negative correlations
with yield and yield components and RF had positive correlations.
Compared to SH, DMT was more closely correlated with yield, KN/ear, and
TKW for three inbred groups. Among Te, Tr, and Te×Tr lines, there were
similar correlation coefficients between KN/ear, TKW and DMT.
