The study found that gene interactions play a significant role in the inheritance of yield and allied traits in opium poppy, with additive gene action being the main driver. Selection based on studied traits can effectively enhance yield potential in opium poppy, while delayed selection for traits governed by epistasis may also yield promising results.
The information on gene interactions is a basic requirement for exploitation of genetic variability and advancement in the development of high yielding lines in any crop. The present study was taken to discover the nature of gene action implicated in the inheritance of yield and allied characters in opium poppy. Three testers and 20 lines of opium poppy were crossed in triple test cross design. The results showed that the additive gene action was significant for most of the characters, though, dominance as well as epistasis also had considerable say in the inheritance of characters. The presence of additive effects for all the traits suggested selection based on the studied traits can enhance yield potential effectively in opium poppy. The delayed selection for the traits governed by epistasis may also deliver promising results in opium poppy.
