In almost crops, hybrid vigour well known as heterosis is easily noticed on quantitative traits since this phenomenon exploited the concept of either dominant or over-dominant genetic effect. Simply, quantitative traits can relate to yields, yield components, or other agronomic characters (plant architechture, flowering traits, abiotic and biotic resistances traits).

Article Perspective of hybrid wheat research: A review
The germplasm having traits that can produce hybrid wheat with more yield should be selected. Yield in term of quantity of grains. At the same time length of the spike and bold grains are also good traits for higher yield. No doubt yield is the most important component BUT the hybrid also must have a good quality i. e., chapati making and acceptability by the consumers.
