Assessment of Marigold (Tagetes crecta L.) Genotypes for Morphological Characters

摘要

The present study was undertaken during 2009-10 to evaluate 17 marigold genotypes for their morphological characters. Various morphological characters were recorded and genotypes were categorised based on the seedling, plant growth, inflorescence andseed characters. With respect to intensity of colouration, all the genotypes showed light anthocyanin pigment except Sirsi local which exhibited dark anthocyanin. Plant height ranged from 27.60 cm (Dwarf orange) to 104 cm (Double orange). Based on flowercolour and incision of margin, Sirsi local (medium orange), Coorg L-l (light yellow) and Coorg L-2 (dark yellow) could be very easily identified, from the rest. Sierra yellow recorded highest seed weight (3.62 g) and lowest in Atlantis gold (2.16 g) with a mean weight of 2.66 g. Thus, the marigold genotypes differed significantly especially for flower and seedling characters which could be used to differentiate the varieties of similar characteristics.
