TRIPLE TEST-CROSS ANALYSIS OF KARNAL BUNT RESISTANCE IN WHEAT (TRITICUM AESTIVUM L.)

Published on

Genetics of Kamal bunt resistance was investigated using triple test-cross analysis in bread
wheat. Twenty nine diverse genotypes were crossed with HD 29 (resistant) and WL 711
(susceptible), true-breeding testers, and their Fl hybrid. The epistatic variation was found
to be an integral part of inheritance of Kamal bunt resistance. Both additive (D) and
dominance (H) geneticcomponents were significantwith partial degree of dominance. Due
to the predominance of additive variance, breeding for Kamal bunt resistance may be
successful with simple selection procedures.
