STUDIES ON THE RELATIONSHIP BETWEEN BARLEY M1 DAMAGE AND M3CHLOROPHYLL MUTATION

Jia Yufeng  
The paper studies the relationship between radiation dosage, M1 plant height, maturity and M2 chlorophyll mutaion frequency by using barley as the material. The results show that M2 chlorophyll mutation frequency of plants radiated with greater dosage is higher. The M1 plant heigt is not re lated to M2 chlorophyll mutation, but the M1 plant maturity is related to M2 chlorophyll mutation, namely, M2 chlorophyll mutation frequency-the offspring of M1 later mature plants is higher than the offspring of M1 earlier mature plants.
