Researches on Heterosis on Yield and Yield Components of Some Poppy Hybrid (Papaver somniferum L.) Lines

The aim of this study is to improve some poppy materials which both the seed yield and capsule yield are higher and its morphine ratio is higher level than the average ratio of the country. The current sown varieties that on the poppy cultivated areas are selected according to the wishes of the producers. The seven lines were crossed reciprocal that were selected in first year of the study which was carried out two years. The parent lines were taken with their hybrids to yield experiments in the second year. Yield components of hybrid and parent lines were compared and investigated for heterosis and heterobeltiosis between these lines. Heterosis and heterobeltiosis values of some important traits of the material have been given below: for seed yield per plant changed between -13.42% to 37.14% and -22.48% to 36.29%; for capsul yield -33.92% to 45.39% and -40.83% to 34.67%; for seed yield -32.05% to 45.89% and -38.34% to 43.22%; for morphine content -24.21% to 44.62% and -32.44% to 32.68%; for morphine yield -37.63% to 100.39% and -54.68% to 95.21%, respectively.
