Abstract:

The ear length, ear diameter, row grains, 100 grain weight etc of corn were studied in dry codition. The result showed that ear length was significantly positive correlated with yield, 100 grain weight and ear length were lightly positive correlated with yield, and row grains was lightly negative correlated with yield. Soil water content was highly negative related with yield, plant height, leaf number and planting density were lightly negative correlated with yield. The variety relatively resistant to dry in filling period were Fenghe7, Suiyu7 and Fenghe332. Xianyu335 was the mediem one, and Longdan13 and Sidan19 were poor ones.
