| Abstract | ||
| Eight groups of the F4 Generation for two crosses in a six –row barley (Jezera-1X Benedict and Baraka X Arivate), each group with ten families in addition to their parents were used to estimate to components of genetic variance, environmental variance, average degree of dominance, heritability and expected genetic advance from selection for grain yield and its Components. Narrow sense heritability was (1) high rot maturity time, plant height and number of spikes in crosses, spike length in the first cross and grain yield in the second cross. (2) medium for grain yield weight of 100 grains and number of spikes in the first cross and spike length in the second cross. (3) low for weight of 100 grains and number of grains per spike in the second cross. The results indicated that selection will be effective to obtain pure lines with superior characters in the two crosses for plant height, number of spikes, spikes length and grain yield. Recurrent selection will be suggested to improve the other characters. | ||
