narrow-sense heritability

(genetics)
The degree to which individual phenotypes are determined by the genes transmitted from the parents; expressed as the ratio of the additive genetic variance to the total phenotypic variance.

Thus, SNP-based heritability estimates obtained from very distantly related individuals will tend to be lower than the true narrow-sense heritability.
Using Warner (1952)'s method, narrow-sense heritability (h2) for all characters and expected direct genetic gains (Allard, 1964) besides indirect genetic responses (Falconer and Mackay, 1996) were determined, and the genetic correlations (rG) between plant height and other traits were calculated using covariance method which was according to Yildirim and Ikiz (1973).
The values of narrow-sense heritability vary from 35% for awn length to 72% for spike weight and seed yield.
Narrow-sense heritability can also be calculated using data from both parents and progenies.
