TRIPLE TEST CROSS ANALYSIS FOR OIL CONTENT, SEED YIELD AND COMPONENT TRAITS IN INDIAN MUSTARD

Abstract

To study the relative magnitude of epistasis in comparison to additive and dominance components in Indian mustard (Brassica juncea), the experimental materials were generated following TIC design [1]. The three testers, DIRA 313, RW 29-6, and their Fl were crossed with ten promising strains i.e. JGM 88-11, KBJ 3, PR 8801, PSR I, RMH11, RN 50, RLC 8662, HLBJ 11, BM 35-9-9 and DIR 412, selected on the basis of their diverse genetic origin. The resulting 20 single and 10 three-way crosses along with ten lines and three testers were grown in randomized block design with three replications.
