Abstract:
Marigold is an annual flower crop that is mostly grown and propagated through seeds. Floret's position within a capitulum in marigold leads to varied differences in the seed quality. Hence, the present study was undertaken to reveal the influence of floret position within a capitulum on seed quality in marigold varieties. Seeds of marigold collected from cultivars, Pusa Deep, Dainty Marietta and Pusa Bahar, October-November and February-March flowering period, 2018-19. The experimental results showed that, of the three different whorls, Outer whorls recorded significantly higher mean values for seed quality parameters viz., germination, seedling length, seedling dry weight, 1000-seed weight and Seed vigour indices (SVI-I and SVI-II); seed geometric properties viz., surface area, length, and perimeter also recorded significantly higher mean values for outer whorls. Seed germination had shown a high correlation with 1000 seed weight and seed surface area. The present study suggested that good-quality seeds in marigolds can be obtained from the outer whorls of the capitulum.
