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.
