ABSTRACT
Standardization of protocol for virus-free sugarcane production were investigated through shoot tip culture of sugarcane was isolated from grown sugarcane tip of explants and cultured on modified Murashige and Skoog (M&S 1962) medium containing auxin (2, 4-D) and cytokinins (KN, BA, BAP) was used to cultivate shoot tip of sugarcane (L) in vitro. Concentration of sucrose was at 3% W/V level, the PH media was adjusted to 5.6 prior to the addition of agar 8% W/V. young shoot tip were cut into thin smaller pieces of 1.0 to 1.5cm length-and inoculated to the media (various levels of hormones and in different combinations), then incubated at 27 ± 20C under light intensity of 2000 – 3000 Lux in the culture room. Treatments 2, 4 – D and BA at levels of 0.8mg/L and 0.25mg/L respectively with GA3 (0.1mg/L) produce optimum multiplication. After having DAS-ELISA test the invitro grown plantlets were being used for massive micro propagation. Visual evaluation of the morphological trials of the shoot tip culture. Derived plants showed normal and free from various diseases. Gross yield was obtained in shoot tip derived plants over their source plants.
Key Words: shoot tip, virus free, plantlets production, sugarcane, invitro micropropagation, culture.
