RODRIGUEZ GARCIA, Armando et al. G*E interaction of 135 recombinant inbred lines of sorghum for biofuel production. Rev. Mex. Cienc. Agríc [online]. 2012, vol.3, n.1, pp.21-34. ISSN 2007-0934.

Sorghum (Sorghum bicolor (L) Moench) is one of the main basic foods forthe poorest people in the world, suffering from a situation of increased food insecurity. This crop is adapted to a warmer and drier agro-ecological environment, where it's difficult to grow other cereals. The formation of outstanding genotypes requires to evaluating the genetic materials in different environments and determines their genotype-environment interaction. The objective was to detect and analyze the genotype-environmentofagroup of recombinant inbred lines and select the highest potential to be used in the production of biofuels. 135 recombinant inbred lines of sorghum were evaluated at different locations during the years 2006, 2007 and 2008. Data from seven variables were analyzed as corresponding to an experiment in randomized block design in each of several environments. Genotype-environment interaction was analyzed using the AMMI model. It was highly significant, scoring the recombinant inbred lines, selecting them by its size and selecting those with less magnitude, the best environment forthe proper development of recombinant inbred lines were determined and, 13 lines with higher sugar content were selected measured in °Bx.
