Abstract:

A field experiment was conducted during rabi season of 2016-17 at Research Farm, Rajasthan College of Agriculture, MPUAT, Udaipur to study “ Genetic Variability and Path Analysis in Opium poppy (Papaver somniferum L.)” was carried out using 25 genotypes were planted in randomized block design including 2 checks. The data obtained were subjected to analysis of variance, estimation of different variability parameters and path coefficient analysis. The observations were recorded on five randomly selected plants for twelve characters. Analysis of variance revealed significant differences among the genotypes for all the characters suggesting sufficient amount of variability in the experimental material under study. High GCV coupled with high heritability and expected genetic gain of a character provides good selection advantage. There is a substantial scope for improvement of seed yield per plant, harvest index for latex yield and husk yield per plant. Selection for these characters would be effective in selection of suitable genotype for opium poppy improvement. Path coefficient analysis revealed that husk yield per plant, number of effective capsule per plant, diameter of main capsule, days to 50 per cent flowering, plant height and was the major components for seed yield per plant and latex yield per plant respectively because these traits had maximum direct and indirect effect towards seed yield and latex yield. The estimate of phenotypic coefficient of variance was higher in magnitude than the respective genotypic coefficient of variance for all the characters indicating the important role of environment in the expression of characters. Chetek Aphim (0.16 g), UOP 121 (0.15g/plant), UOP 30 (0.14g/plant) and UOP 53(0.13g/plant) were found superior for latex yield and genotype UOP 53 (7.52 g/plant), UOP 150 (6.41 g/plant) and JOP 540 (6.31g/plant) for seed yield. The genotype UOP-53 found superior for both latex and seed yield per plant.
