The conventional propagation of plantain (Musa spp.) throughshoots from the mother plant, besides its low multiplicationrate, facilitates the plagues and disease dissemination. Therapid multiplication technique, an alternative in healthy plantproduction, was utilized for the multiplication of PlatanoEnano (PE) and CENSA ¾ (C 3/4) plantain cultivars in twonurseries in Rivas and Nandaime. 19 propagation beds wereused in each location. In Rivas 3 933 PE and 2 307 C ¾ cormswere sown in construction sand (CS) and soft water beach sand(BS) as substrates at 2.5 cm between corms, microaspersedand fertilized with 15-15-15 NPK. In Nandaime 6 962 PEcorms were sown in CS, watered manually, and fertilized withSuper Fertil and Super Calcio. Plants growing from corms ofboth cultivars were incised and sown in plastic bags, in Rivason a mixture of sand-organic matter-soil, in Nandaime in soil.The shooting index (SI) per corm in localities, cultivars andsubstrate types was calculated. In Rivas the SI for PE was4 and 4 for C ¾. In Nandaime the SI for PE was 3. The SIfor PE established in CS was 5 and 3 in BS. The better SI ofPE obtained in Rivas could be explained by the immediateutilization of fresh corms and shoots with better physicalconditions compare with corms used in Nandaime. 17 039PE and 9 052 C ¾ plants in Rivas and 21 637 PE plants inNandaime were produced. The SI registered in both localitiesand cultivars are lower that those reported in the UNAtechnicalguide. Recommendations of the technical guide-UNA in corms field selection, sowing distance and time tocollect plants were not accomplished.Keywords: Rapid multiplication technique; plantain; shootingindex; commercial application.DOI: 10.5377/calera.v9i13.17
