Abstract
Cassava (Manihot esculenta Crantz) is widely grown in tropical and sub-tropical regions of the world primarily for its starch-rich roots and, in some cases, its nutritional foliage.The overarching goal of this paper was to generate a comprehensive information on the status of the involvement of plant growth regulators and varieties in the multiplication of cassava planting materials with particular reference to Rwanda.This information will provide a platform and further strengthen the knowledge base on the application of plant growth regulators (PGRs) by stakeholders in producing clean, high-quality cassava plantlets.We demonstrated the interactive effect between different phytohormones and varieties.The study showed the classical plant response to hormones with an increase in triggering an optimal value before inhibition sets in.Phytohormone, 1-Naphthaleneacetic acid (NAA), and benzyl adenine (BAP) were reported as being crucial in root and shoot growth, respectively:-with 10 mg/l being optimal doses.The outcome is crucial in recommending users the choice of hormone and specific varietal combinations and points to the fact that various PGRs concentration levels can be conveniently utilized successfully in the multiplication of different cassava varieties.Since the hormonal response has been shown to trigger differential reactions between different varieties, adopting such technologies needs to be considered with caution in consultation with researchers and policymakers to avoid adverse effects.In conclusion, the rapid multiplication of cassava planting materials depends on the PGRs concentration levels and their admixtures, the genetic makeup of the varieties evaluated, subculture type/ number, and shoot tip/ nodal segment used. HIGHLIGHTSm Cassava is mainly grown primarily for its starch-rich roots and, its nutritional foliage.m Whereas 1-Naphthaleneacetic acid plays a key role in triggering root growth, benzyl adenine is crucial in enhancing shoot growth.m For rapid multiplication of cassava planting materials, the optimal doses for these phytohormones ought to be 10 mg L -1 .
