Contributing traits in barley

Barley is the world’s fourth most cultivated cereal and is an important crop model for genetic studies. One layer of genomic information that remains poorly explored in barley is presence/absence variation (PAV), which has been suggested to contribute to phenotypic variation of agronomic importance in various crops.

A set of diallel crosses involving 10 diverse parents (excluding reciprocals) was made. Heterosis for grain yield per plant ranged from -21.95 to 39.65 per cent and -48.13 to 64.34 per cent under normal and late sown conditions, respectively. Out of 45 crosses fifteen crosses in both the sowing conditions exhibited positive significant heterosis while, nine crosses in normal and seven crosses in late sown condition exhibited positive significant heterobeltiosis.

Salinity tolerance is a physiologically multi-faceted trait attributed to multiple mechanisms. Three barley (Hordeum vulgare) varieties contrasting in their salinity tolerance were used to assess the relative contribution of ionic, osmotic and oxidative stress components towards overall salinity stress tolerance in this species, both at the whole-plant and cellular levels.

The present study was carried out at Dept. of Genetics and Plant Breeding, BHU during rabi of 2016-17 comprising of 101 barley genotypes. Association of yield and its contributing traits was analyzed and these correlations were partitioned to have clear understanding direct and indirect effects on the grain yield per plant under terminal heat stress.
