Abstract

The agronomic traits and resistant responses of 20 maize populations were investigated.The evaluations for two consecutive years showed that BSLCSC7 was rated as highly resistant,6 populations such as BS10CFRC10,BS12CH1C8,BS26 as resistant,and 7 populations such as BSCAD-1,BSCAD-2,BSCAD-3 as moderately resistant,and the others as susceptible or highly susceptible.Most populations tested had good adaptability in Heilongjiang province,and BSCAD-3 and BS12CH1C8 have good performance in grain yield and yield components and head smut resistance which could be used in breeding program.
