• Only true to type plants are permitted for flowering which are of qualitatively potential.
• Less qualitative plant like disease plant, damaged plants, insect attack plant, unhealthy plants, etc. are rouged before flowering.
• Isolation distant : For foundation seed production = 1600 m and For certified seed = 1000 m

Field Inspection and Rouging :

Minimum no. of field inspection on Rayo is 3.

1. Before full grown /marketable stage.
2. Bolting/Flowering stage
3. Seed Maturation stage

Seed Harvesting :
