Plant breeding from laboratories to fields

the latex oozes out. The mature green capsule is lanced with an instrument called “Nastar” having 3-4 small blades designed to ensure uniformity in depth of incisions. Generally 3-4 lancing is done in each capsule with parallel longitudinal cuts which is performed after mid day and allow the latex to remain overnight on the capsules for coagulation. In the follow‐ ing morning the latex is collected from the capsule walls with blunt edge of small iron scoop. The opium is kept in small plastic box or earthen pot or copper bowls. The latex col‐ our varies from dark to light brown to pink based on the variety. The depth of incision should not be more than 1.2 mm. After collection of opium, lanced capsules are left to dry over plants for next 15-20 days for harvesting of seeds. correlation and path analysis for opium yield, seed yield and eight component traits in a group of 101 germplasm lines of different ecogeographical origins. They noticed high heritability coupled with high genetic advance and coefficient of variability for most of the traits. Path coefficient analysis indicated that capsule per plant had high direct path towards opium yield followed by four other traits.
