Field response of 'Dwarf Cavendish' plants (Musa AAA) obtained by somatic embryogenesis
Journal Title: Biotecnología Vegetal - Year 2010, Vol 10, Issue 4
Abstract
Somatic embryogenesis (SE) has been developed in several species of plants with different objectives. Even though, the mass production of plants and the evaluation of field behaviour in big populations been achieved in few cases. Somatic embryogenesis has been developed in some cultivars of Musa spp. to facilitate protocols of genetic transformation. Though, this technique can be an alternative to increase the efficiency for mass production of in vitro plants to commercially scale for cultivation in productive areas. The aim of this paper was to defermine the fiel behaviour dwarf of Cavendish plants obtained by somatic embryogenesis. The evaluations were carried out about the stability of the some morphological and quantitative characters of the plants related to the yield components were evaluated. The agricultural yield, under production conditions, of this plants compared to plants derived from suckers, conventionally cultured, was also determined. Results indicated that plants obtained by SE presented very few indexes of morphological variation in both productive cycles. The agricultural yield was superior with regard to the plants obtained by suckers in both cycles. Results of a population evaluated of more than 5 000 plants, obtained by SE in the cultivar ‘Dwarf Cavendish’, constituted a reliable evidence to recommend this method as a viable alternative for the in vitro mass propagation of plants in this cultivar.
