Abstract

Soybean (Glycine max L.) is an essential oilseed crop widely recognised for its high protein and oil content. Soybean (Co1) is a high-yielding variety and well-suited for cultivation in Tamil Nadu and nearby regions. Direct and indirect organogenesis of soybean using different growth regulators is helpful for regeneration, micropropagation and genetic transformation. We evaluated the impact of various plant growth regulators (BAP, KIN, ZT and TDZ) for direct organogenesis using split seeds and cotyledonary nodes of soybean (Co1). Among the different combinations, B5 medium with BAP 1.0 mg/L (for multiple shoots) and KIN 1.0 mg/L (for shoot length) revealed the better outcomes for the direct shoot rejuvenation in the split-seeds. The highest frequency of multiple shoots from the cotyledonary node was induced in MS medium containing TDZ at 0.5 mg/L. Different levels of 2,4-D have been assessed for callus induction from various explants and a higher percentage of callus was developed in hypocotyls. MS media containing 2,4-D (2.0 mg/L) and KIN (0.2 mg/L) leads to better callus development and the friable callus was further used for shoot induction using BAP, TDZ and ZT. After 2 - 3 weeks, initiation of shoot formation from embryonic callus was observed in MS medium supplemented with 1.0 mg/L ZT and 0.5 mg/L IAA. Shoot induction from split seeds showed better response than the cotyledonary node and callus. These findings are expected to be useful for the regeneration of soybean (Co1) to develop transgenic lines for enrichment of nutritional value.
