Genetic diversity Evaluation of Elymus hispidus and E. pertenuis In Isfahan Province

摘要: For Forage plant production that my country need, we must know Forage plantproduction sources especially Grasses, carefully and completely. This project was done for found genetic parameters information and data of 2 forage grasses species genotypes include of 35 accessions of Elymus hispidus and 41 accessions of E. pertenius from 2001. At first we collected accessions seed samples of this 2 forage grasses species from 10 Islamic Republic of Iran provinces. Seed accessions were cultivated through sward method and spaced method in irrigated condition of Shahid Fozweh Research Station and in dry condition of Zayanderood Watershed Management Research National Station in form of randomize complete blocks design with 3 replications in autumn of 2002. In 2003 didn't record any data, due to insufficient plants growth. Characters included of seedling establishment, plant succulence, plant height, forage dry yield, ear emergence, leaf width, ear length, biological persistency, digestibility, soluble carbohydrate, Crude Protein (CP), Crude fiber (CF), neutral detergent fiber (NDF) and Total ash (ASH) were determined from 2004 to 2005. Results of combined analysis of variance were shown there are significant differences between E. hispidus accessions. Accessions of Ghalaeh Arezomand 2, Ghalaeh Arezomand 3, Dolatgharin, Bidghatar, Meymand and Bijar were the best genotypes with 2028-4476 Kg/ha forage yield. Dry forage yield total average of E. hispidus species was 1.9 Ton/ha. The correlation between dry forage yield with plant succulence, biological persistency and soluble carbohydrate were positive significant but with ASH …
