Abstract

Marigold (Tagetes erecta L.) is one of the most important loose and cut flowers in India. It belongs to the family Asteraceae and native of Mexico. Genotype Nilakkotai local orange shown good growth, yield and quality under hill zone conditions compared to other genotypes. The genotype Nilakkotai Local Orange recorded the maximum plant height (104.20 cm), number of Primary and secondary branches per plant (17.73 and 29.27 respectively), number of leaves per plant (392.47), Stem diameter (17.43 mm) and internodal length (7.53 cm), whereas minimum plant height (66.80 cm), number of leaves per plant (135.53), Stem diameter (9.99) was recorded in the genotype Pusa Narangi Gainda. In case of flower yield and quality attributes such as number of flower per plant (59.4), flower yield per plant (529.33 g), petal meal yield (122 g/kg), flower diameter (8.47) and xanthophylls content (20.19 mg/g petal meal) whereas minimum number of flower per plant (20.60), flower yield per plant (120.93 g) and petal meal yield (72 g/kg) was recorded in the genotype Dwarf Yellow. Among these marigold genotypes studied, better performance in terms of vegetative growth, flower yield and quality parameters, genotypes Nilakkotai Local Orange, Coimbatore Local orange, Coimbatore Local Yellow were found promising for loose flower production under hill zone condition of Karnataka.
