Tolerance of Maize(Zea mays L. )to Chlorsulfuron

Tolerance of Maize(Zea mays L. )to Chlorsulfuron

Fourteen inbreds of maize were tested for the tolerance to chlorsulfuron with the method of seedling wa- ter culter. Significant difference existed in the tolerance of different type maize when tested with 1 and 2 μg/ kg of chlorsulfuron. The tolerance in different type maize wa dent＞flint＞sugar＞midiem＞super sugar pop. The tolerance of different inbred maize was negative correlated with the concentration concentration of chorsulfuron. The tolerance of hybrids might have some relation with their parent lines because in this test the hybrids response to chlorsulfuron showed significant positive correlation with that of tits female parent which suggented some maternal in inheritance and was not controlled by nuclear. It was possible that toler- ance of maize to chlorsulfuron was cytoplasm inheritance.
