Abstract

In order to investigate variation in qualitative and quantitative traits, 19 accessions of ELYMUS HISPIDUS were studied based on a randomised complete block design (RCBD) at Hosseinabad station, Shiraz, Iran. Data were collected and analyzed three years on dry matter (DM) yield, plant height, stem number, leaf to stem ratio (LSR), as well as five QUALITY traits as: dry matter digestibility (DMD), water soluble carbohydrate (WSC), crude protein (CP), acid detergent fiber (ADF) and total ash. Significant differences were observed between the studied genotypes for all of the traits except for LSR, CP and ash. Khoshyeelagh (Gorgan), Patava (Yasuj), Sabzkoh (Chaharmahal) and Mimand (Yasuj) genotypes with average values of 4034, 3068, 2942 and 2450 kg/ha had higher annual DM yield. Khoshyeelagh and Mimand genotypes had hugher QUALITY and recognized as the best genotypes for both yield and QUALITY for cultivation in Fars province, Iran. Results of correlation showed positive correlation between DM yield with plant height and stem number, DMD was positively with WSC and negatively correlated with ADF. Relationships among CP and total ash were positively significant. Using principal components analysis, the first four components determined 76% of the total variation. Five QUALITY traits (DMD, WSC, CP, ADF and ash) were determinant in the first component. DM yield and stem number were important traits in the second components. The genotypes were grouped into 4 clusters based on Ward CLUSTER ANALYSIS method.
