DETECTION OF ADDITIVE, DOMINANCE AND EPISTATIC VARIATION IN WHEAT USING TRIPLE TEST CROSS METHOD

Published on

Sixty progeny families were produced bycrossing20 wheat varieties with three male testers
(WH 147, WH S42 and their Fd in a triple test cross fashion to detect epistasis and test and
estimate additive and dominance components of genetic variation. Epistasis was present
for plant height and 1000-grain weight in both environments. Testers were adequate for
grain number. Additive component played a greater role in the control of almost all the six
characters.
 

Keywords: Wheat, triple test cross, epistasis, genetic variation.
