Eight parents and their possible crosses (Excluding reciprocals) of opium poppy were grown at experimental farm of Plant Breeding and Genetics, Rajasthan College of Agriculture, Maharana Pratap University of Agriculture and Technology, Udaipur (Rajasthan). This experiment was conducted in random block design with three replication and estimate heterosis and yield related traits. Analysis of variances indicated significant variability among parents and their hybrids for all the eleven characters studied. Significant parents v/s hybrids contrast for all the characters except for plant height, peduncle length and diameter of main capsule in pooled over environments indicated the presence of heterosis for these characters. The experimental result for heterosis revealed that out of 28 hybrids, 16 hybrids recorded significant positive heterosis for latex yield per plant, nine and six hybrids recorded significant positive heterobeltiosis and economic heterosis for latex yield per plant, respectively. The crosses UOP-53 X UOP-1185, UOP-80 X UOP-20, UOP-79 X UOP-1185 and UOP-79 X UOP-20 showed the highest magnitude of heterosis and heterobeltiosis for latex yield per plant, seed yield per plant, husk yield per plant, days to 50% flowering and seed harvest index. The crosses UOP-79 X UOP-60 and UOP-80 X UOP-20 showed highest significant positive economic heterosis for latex yield per plant, seed yield per plant, husk yield per plant, effective capsules per plant, days to 50% flowering, morphine content and seed harvest index.
