Four wheat (Triticum aestivum L.) crosses with the cultivar ‘Glcnlea’ as a common female parent were used to investigate response to selection for yield in the F 3 generation. Selection was based on the mean performance of F 3 lines (seed from a single F 2 plant) grown in three replicate, three-row plot yield.

Rasmusson & Cannell () selected lines for low and high yields and yield components in the F4 generation of barley. They observed that selection for.

The grain yield of wheat is determined by three yield components: productive spikes per unit area, number of grains spike -1 and grain weight (Tian et al., ).

Correlation analysis provides information about association of plant characters and therefore, leads to a directional model for yield prediction (Ashfaq et al., ).

influence grain yield in wheat are more heritable than yield itself (Fethi and Mohamed, ). The high heritability resulting to high genetic advance for yield components in wheat offer better scope of selection of genotypes in early segregating generations (Singh & Chatrath ; Memon et al., ). In this regard heritability.

The target environments for crop yield forecasting have always been two-fold. In countries with highly mechanised large-scale agriculture, such as the USA, Europe and Russia, crop yield forecasting provides data to governmental structures, companies and farmers.

Good yield and price predictions provide a clear strategic Size: 2MB. Therefore, selection of superior plants can be done in early generations for development of better wheat genotypes.
