Inheritance of Marigold Flower Characteristics

Abstract

Inheritance of two characteristics of marigold, flower form and color, was studied by making cross and reciprocal cross of various marigold types, total of 42 crosses. For flower color, it was found that more than one genes, probably 3, governed this character with additive gene action. Number of gene that controlled ray floret and disc floret might have governed by a single gene with dominant gene action for ray floret, whereas with additive gene action for disc floret. Each characteristics was independent. Number of chromosomes count from root tip of marigold  were 2n = 24 in all parents and hybrids.
