Abstract: Maize stover is the important resource as forage. With technique of near infrared reflectance spectroscopy, forage quality traits such as in vitro dry matter digestibility(IVDMD), acid detergent fiber(ADF), neutral detergent fiber(NDF)and water soluble carbohydrate(WSC) of maize stover about 44 varieties were evaluated. The Results showed that there were significant differences in IVDMD, ADF, NDF and WSC among varieties. The four forage quality traits were almost accorded with normal distribution respectively. IVDMD ranged from 38.60% to 51.74%, ADF ranged from 27.01% to 35.67%, NDF ranged from 51.55% to 65.81% and WSC ranged from 4.69% to 12.21%. The coefficient of variation(CV)of WSC was the highest which was 23.59%. IVDMD was significantly and negatively associated with ADF and NDF, and positively associated with WSC. There was a significantly positive correlation between ADF and NDF. WSC was significantly and negatively associated with ADF and NDF. There were five elite varieties with high IVDMD and WSC and low ADF and NDF.
