Seed production

• An isolation distance of 100 to 200m for certified and foundation seed plots respectively should be maintained between two cultivars. During crop period at least 3 times plants should be rouged off. First rouging should be done before flowering and on the basis of foliage characters, the off types has to be removed. Second rouging is done at the time of flowering on the basis of flower characters and off types are to be removed. Final rouging is to be done at the fruiting on the basis of fruit characters and off types.
• At all the stages disease/pest affected plants should be removed. At ripening, the fruits become light yellow in colour and at this stage they are harvested and seeds are extracted properly. The fruits are cut into pieces and washed in clean water and the seeds settled down in the bottom of the pot are collected. The seeds should be dried completely and kept in cool place.
