Abstract


The variability of in vitro regeneration and proliferation of maize genotypes POOLISSRQPMX, DTSR-WCO, TZLCOMP4C3, TZE COMP 3C2, EV99QPM, POP66 SR/ACR94-YQPM, DTSR-WC, SAMMAZ 19S-14DT and TZEE-YPOPSTRC4 was investigated. Explants were regenerated through direct organogenesis using 0.1 mg/l NAA + 2.0 mg/l BAP, 0.1 mg/l NAA + 2.0 mg/l KIN, 0.3 mg/l NAA + 3.0 mg/l BAP, 0.3 mg/l NAA + 3.0 mg/l KIN, 0.5 mg/l NAA + 4.0 mg/l BAP, 0.5 mg/l NAA + 4.0 mg/l KIN and MS medium only. The regenerated maize yielded the highest number of multiple shoots (1.70 cm) and shoot length (3.35 cm) on MS medium supplemented with 0.3 mg/l NAA + 3.0 mg/l BAP within 31 days. Genotype EV99QPM and DTSR-WCO had the highest number of shoots, rooting traits respectively.
