Field evaluations of potato somaclones (Solanum tuberosum Lin.) Of the variety "Desirée" obtained by somaclonal variation and in vitro mutagenesis
Journal Title: Biotecnología Vegetal - Year 2002, Vol 2, Issue 1
Abstract
One evaluated the yield and its components, the percentage of affectation as opposed to Alternaria solani (Sorauer), the number of tubers that presented affectations by Streptomyces scabies (Thaxter) Wakman and the morphologic variations in tubers. The parameters previously mentioned were evaluated in somaclones IBP-10, IBP-27 and IBP-30, as witness were used the variety Desirée, that it is the variety from which they originated somaclones studied. Somaclones IBP-10 and IBP-27 presented yields similar to the original variety, the lowest values were reached about somaclon IBP-30. With respect to the diseases somaclones presented inferior levels of affectation to the original variety front to Alternaria solani, in the evaluation of the number of tubers affected by the common scab was observed that somaclon IBP-30 presented the greater percentage of affected tubers, the IBP-10 the smaller percentage and the IBP-27 presented an intermediate behavior. Changes in the color of the skin and the form of tubers were observed. Somaclón IBP-10 presented yellow coloration in the skin and forms oval small, somaclon IBP-27 presented oval form in the tubers.
