DEVELOPMENT OF BRASSICA NAPUS L. LINES FOR HIGH YIELD AND ESSENTIAL FATTY ACIDS

Heterosis and combining ability were calculated for 13 different morphological, yield, quality-related traits of 18 F1 Brassica napus hybrids developed through line × tester mating design using 6 lines 3 testers along with their parents. Line ANOVA revealed highly significant results among all characters except primary branches per plant. ZM-R-2 (tester) was identified as a good general combiner for, days to 50% flowering, siliqua formation, linolenic acid (%), number secondary branches, siliquae plant, seeds siliqua, while ZM-R-6 100-seed weight, protein, oleic percentage. ZM-R-11 specific (-5.19**, -4.70**, -5.37**), ZM-M-6 ZM-R-2, ZN-M-9 ZM-R-6, ZN-R-8 Shiralee combiners oil, protein percentage, respectively. Highly desired mid-parent heterosis observed ZM-R-7 morphological quality like content oil (24.87**) (19.27**). Positive mid parental (46.81**), linoleic acid, seed yield plant-1 in ZM-R-10 ZM-R-10. These can be utilized source genetic material future breeding programs.
