Combining Ability in Plant Breeding | GCA vs SCA Explained

Combining ability is one of the most important concepts in plant breeding used to identify superior parents for hybrid development. In this video, we explain the concept of General Combining Ability (GCA) and Specific Combining Ability (SCA) in a simple and easy-to-understand way. The concept was first introduced by George F. Sprague and Lloyd A. Tatum while studying hybrid performance in maize. Today, combining ability analysis is widely used in hybrid breeding programs of crops like rice, sorghum, sunflower, and cotton.
