Triple test cross analysis in two wheat crosses

Abstract

Modified triple test cross analysis described by Jinks and Perkins (1970) has been applied to the study of additive, dominance and epistatic components of genetic variance for five metric traits, namely final plant height, ear length, number of spikelets per spike, number of grains per spike and grain yield per plant, in two wheat crosses (Kalyan Sona x Norteno 67 and Norteno 67 x WL 212). The results of the analysis reveal that the epistatic component is an important element in both the crosses for all the five characters. © 1976 The Genetical Society of Great Britain.
