Webpotent offspring, they are said to have good combining ability.4 At first, combining ability was a general concept used collectively for classifying an inbred line respective to its cross performance but was later amended. Two concepts of general combining ability influence on inbred line evaluation and population development in Webcombining ability, whereas the non-additive fraction of the total variance is included in the variance for speci fi c combining ability, which is caused by dominance and epistatic deviations [9,11]. Specifi c combining ability is a key measure of an inbred line's ability to produce superior hybrid combinations [12].
