Increasing Seed Weight in Wheat and Its Effect on Yield, Yield Components, and Quality¹

High seed weight was transferred from ‘Selkirk’ to ‘Thatcher’ spring wheat Triticum aestivum L., by backcrossing. On the average the backcross lines with high seed weight outyielded Thatcher. However, their yield varied considerably depending on the degree of compensation in the other yield components, seeds per spike and spikes per plot. Weight per seed was positively correlated with yield and negatively correlated with number of kernels per plot. The number of kernels per spike showed a high negative correlation with the number of spikes per plot. Some of the highest-yielding backcross lines appeared to be equal to Thatcher in milling and baking quality.

Key Words: Quantitative character • backcrossing
