Abstract
The present study two field experiments material comprised of one thousand and twelve genotypes of barley during 2003/2004 and 2004/2005 seasons to study characterize and evaluate the 1012 accessions for important agronomic and morphological traits which could be used in barley breeding ..
Grain yield of accessions of two and six rowed barley was normally nearly 27% of the two rowed had yield higher than 8-11 g ,but only 26 % of the six rowed type .Over 17 % of the six rowed type fell in the class 16- 19 g against 16 % in the same class .Although 6- rowed type predominate in Egypt barley cultivation ,the above result suggests that six rowed barley could be introduced successfully .
The interrelationships showed positive and significant phenotypic correlation between barley grain yield /plant and each of plant height ,spike length ,number of kernels /spike ,100 kernel weight and number of spikes /plant in the six and two rowed barley .However the phenotypic correlation of grain yield /plant with each of flag leaf glaucosty sheath ,ear glaucosty and grain speculation of inner lateral nerves of dorsal were negative and significant in the six rowed barley .
The path analysis showed that the number of spikes /plant , number of kernels /spike and 100 kernel weight had high direct effect and /or indirect effect through each others on grain yield /plant ,so, the barley breeder might take them into consideration in the selection programs aiming to improve new barley .
