GENETIC VARIATION FOR SEED PROTEIN IN BARLEY GERMPLASM
ZAHEER AHMAD AND SHAHEENA YASMIN
Abstract
Barley accessions collected from three regions of Pakistan were evaluated for seed protein (%) for two seasons. A wide range of variation (9 to 21%) was found in the germplasm studied during both seasons. Maximum accessions exhibited protein 12.1 ~ 16.0% protein whereas few accessions produced more than 18.0% protein. Correlation between two seasons’ data was highly significant indicating the influence of genetic component. Germplasm were classified on the basis of regions. Accessions from Northern areas possessed average higher protein percentage followed by NWFP, Baluchistan and check varieties. Classification on the basis of altitude showed that the accessions collected from 200-800 masl had low protein while those collected from 2601-3000 masl had high protein. This study provides information on important protein sources of germplasm.
