Summary

The triple test cross analysis (Kearsey & Jinks, 1968; Jinks & Perkins, 1970) was used to detect and estimate the additive, dominance and epistatic components of genetic variation for four metric traits, namely, final plant height, number of spikelets per spike, 100-kernel weight and yield per plant, in the first backcross populations of four wheat crosses (Norteno 67 α Moti, Sonalika α Moti, Kalyan Sona α Sonalika and Kalyan Sona × NP 876). Epistasis was a more important component of variation for final plant height and yield per plant than for number of spikelets per spike and 100-kernel weight. On the other hand, the additive component was highly significant for all four characters in all eight backcrosses.
