Abstract

A study on evaluation of sixteen African marigold genotypes viz., Arka Bangara,, Arka Bangara-2, Arka Agni, Pusa Basanthi Gianda, Pusa Narangi Gianda, Dharwad local, Raichur local, Shahapur local, Ashoka orange, Ashoka yellow, Bhuvan Orange, Maxima yellow, Yellow gold, Indam yellow, Vigro Hybrid Orange, Marigold African Giant for their flower yield and xanthophylls content was carried out in RCBD at College of Agriculture Bheemarayanagudi during 2015-16. Maximum flower yield cv. Arka Bangara-2 (21.77 t/ha), followed by cv. Maxima yellow (19.01 t/ha), cv. Arka Agni (17.13 t/ha) whereas, lowest in the cv. Indam yellow (7.51 t/ha). Highest petal meal yield cv.Arka Bangara-2 (62.30 g/kg and 1.40t/ha of fresh flowers), followed by cv. Arka Agni (51.70g/kg and 0.98t/ha), while minimum cv. Indam yellow (26.21 g/kg and0.27t/ha of fresh flowers) higher xanthophyll content cv. Arka Agni (21.37 g/kg and 20.80kg/ha of fresh flowers) followed by cv. Ashoka orange (15.08 g/kg) minimum in the cv.Arka Bangara (3.52g/kg) and cv. Indam yellow (1.01kg/ha).
