Fruiting Efficiency in Iranian Wheat Cultivars: Genetic Changes over Time and Associations with Agronomic Traits

Fruiting efficiency (grain set per unit of spike dry weight at anthesis) could be considered as a promising trait for further improvement in wheat grain yield. The aims of this research were to study genotypic variations for Fruiting Efficiency (FE) among Iranian wheat cultivars, its change during past breeding activity as well as its association with main stem grain yield and its component. Eighty-one wheat cultivars released from 1930-2006...
