Analysis of stability and heritability for major agronomic characters in recommended barley cultivars

The performance stability and heritability of thirteen recommended barley cultivars grown at four sites in 1982 to 1983 were studied. Albori and Gangbori with a relatively high mean yield possessed high stability over a wide range of environments. The direct effects of number of spike most positively influenced yield, but those of number of spikelet and 1,000 grains weight were very low. The heritability values of heading and maturing dates, number of spikelet, and winter hardenss were high, but the valus of 1,000 grains weight was very low. The positive genotypic correlations were found for yield with heading and maturing dates, and number of spike, but the negative correlation with winter hardness.
