Clonal propagation is one of the most effective tools for improvement in forestry.The study describes the scope and development of clonal propagation technology for Bixa orellana commonly known asAnnatto. Developing rapid andimproved clonal study reveals that clonal prorogation is possible through stem cuttings collected from matured trees.The study standardized the effect of cutting size, concentration of IBA and root media on success and survival of stemcuttings in this species. Percentage rooting and primary root number differed significantly between treated anduntreated cuttings. Treatment of cuttings with 4000 ppm IBA maximized rooting (83.30%), along with increasedsurvival (78.30%) and primary root number (20.20). Rooting success and root number were better in 15 cm x 20 mmdiameter sized cuttings. Cuttings planted in sand: soil (1:1) rooted better with more roots ensuring better survival.Survival and growth of the clonal plants were best when using improved techniques like size of the cuttings with properconcentration of IBA and also combined with suitable rooting media. However, there was significant variation in heightgrowth (shoots sprouts length) of cuttings due to IBA treatments. The results suggested that it could be possible toproduce clones of high yielding superior genotypes of Bixa orellana on large scale through stem cutting forpopularization and establishment of commercial forestry and agroforestry plantations.
