Genetic and phenotypic variability of grain mass per spike of winter wheat genotypes (Triticum aestivum L.)

Abstract

Variability of grain mass per spike were studied in 10 wheat genotypes. Wheat genotypes were grown during three years on the experimental field in three replications. Samples of 60 wheat plants (20 plants/replication at each year) were analyzed in full maturity stage. The differences in average values for all the studied traits among investigated cultivars were determined. The expressed variability of grain mass per spike estimated by coefficient of variation (CV) which value was CV=5.60%.
