This work was carried out to evaluate morph agronomic parameters on field conditions plant populations of grain sorghum [Sorghum bicolor (L.) Moench] variety CIAP 132R-05 regenerated via somatic embryogenesis. Plants regenerated from somatic embryos use as plant material in the present work were compared with plants grown from botanical seeds. Quantitative characteristics of the two populations correspond to those listed in the National Register of Commercial Varieties of Cuba. However the population of plants derived from somatic embryos showed significantly higher values in terms of: plant height, stem diameter, length and width of limbo and panicle, fresh and dry weight of panicle length assertion, grain length, number of spikelets per panicle, number of grains per spike and panicle, fresh and dry mass of 1000 grains and agricultural yields. These assessments allowed determining the phenotypic stability of the regenerated plants via somatic embryogenesis, by assessing morphological characters in field conditions.
