The Study of Heredity Regulation on Resistance to Wheat Stripe Rust

This paper analysis the relations between the resistance of the parent and F1,F2.The experimental results indicate that: F1 will be high disease-resistance when Parent is high disease-resistance.The resistance immunity of wheat to stripe rust mainly show dominant effect.The proportion of the immunized plant of descendants in wheat is higher.The number of the immunized plant and high disease-resistance plant in F2 relates to the resistance of the parent.The parent is high disease-resistance,the proportion of the immunized plant and high disease-resistance plant of descendants will higher.
