French marigold varieties in Beyblade MI57070 and French marigolds MI57080 species is between breeding for use as pot marigolds. But the problem of seed collected from breeding quality unsuitable for cultivation. Therefore conducted a study on the development of the seed. To find the physiological range (Physiological Maturity; PM) and the appropriate harvest (Harvesting Maturity; HM) for information leading to the production of seeds anyway. The French marigolds planted commercial varieties. Brad MI57070 species in the plots and MI57080 1 Department of Horticulture, Livestock University.

This fresh weight, dry weight, the moisture inside the kernel. Germination index and germination of seeds of commercial varieties were seeded French marigolds. Species in Beyblade MI57070 and MI57080 term PM at the age of 22, 17 and 21 days after flowering, respectively, live weight (per 25 seeds) was 0.36, 0.39 and 0.41 g dry weight (per 25 seeds) 0.31. , 0.21, 0.30 grams of moisture within the seed, 14.28, 46.98 and 26.65 percent germination percentages were 54, 90 and 75 percent of the index grew 3.09, 5.67 and 2.36, respectively, and is HM the age of 23, 18 and 22.
