The phenotype plasticity of husk plays essential roles in disease resistance,insect infection and the rate of grain dehydration during the introduction of maize inbred lines from different environments. In this article,the husk traits of 50 inbred lines from 5 heterosis groups (referred to as heterotic group) in 3 environments including Sanya City,Hainan Province in 2014,Beijing City in 2015 and Tieling City,Liaoning Province in 2017 were measured. The coefficient of variation of husk traits was calculated. The variations of phenotypic plasticity of husk length (PHL),phenotypic plasticity of husk width (PHW) and phenotypic plasticity of husk layer number (PHN) among heterotic groups and the correlation within heterotic groups were analyzed. The changes of meteorological factors in different environments and growth periods were compared. The results showed that the traits of husks were significantly affected by environment. Among all lines,Lüda Red Cob and TangSPT groups,PHL and PHW were significantly positively correlated. While in Reid group,PHL and PHN were extremely significantly negative correlated. The phenotypic plasticity of husk among different maize germplasms had significant variations. PHL and PHW had the characteristics of coordinated regulation. The husk length in Lüda Red Cob group,husk length and width in PB group were insensitive to environments. These two traits remained stable during introduction to other environments. The PHL in Lancaster group was higher than that in other groups,meeting the requirements of the long husk in the South and the short husk in the North. This kind of breeding material is suitable for introduction in different places in the north and south. The average temperature and humidity in the meteorological factors were quite different at the early growth stage of maize. There was a big difference in the sunshine time at the early,middle and late growth stages of maize. It is indicated that sowing early in high temperature area and late sowing in low temperature area is beneficial to reduce the difference of husk traits among environments.
