Rouging on basis of leaf size, shape and colour, vigor, bushy or training habit.During flowering and immature fruit stage:a. Check for flower colour, ovary shape, size, and colour, fruit shape and colour of thevariety to be taken in seed production programme.Maturity stage:a. Check the fruits of the seed crop variety, in respect to size. Color and shape.b. During all the three stages wild species plants as well as mosaic affected plants.Invariably be rouged out.Cucurbits should be allowed to reach full maturity stage to get the seed of higher germination. In bottlegourd, sponge gourd and ridge gourd along with some others do not pose problem for maturity but incase of muskmelon and water melon more care needed to harvest only matured fruits.- 90 -
(Seed Health Management for Better Productivity)Seed extractionIt is more important to extract the seed from the matured fruits at appropriate time and method tobe used to separate the seed; because slight ignorance may deteriorate the germination. In bottlegourd, sponge gourd and ridge gourd fully ripened and dried fruits are crushed and seeds areseparated.YieldS.N. Name of crop Seed yield/ha.
