Descrição morfológica da linhagem ‘UFRB 93’ de Ricinus communis L

Abstract

Given the problem of depletion of fossil fuels combined with the environmental impact of global warming, it is necessary to replace the current energy matrix with another, preferably renewable and with sustainable characteristics. Thus, the oil study of plant species such as castor bean (Ricinus communis) and the characterization of strains that have desirable characteristics for cultivation and management have become increasingly important to evaluate potential strains for industrial use. Thus, this work aims to describe, by morphological data, the strain 'UFRB93', a candidate for cultivation for launching at the Ministry of Agriculture, Livestock and Supply (MAPA), under NBIO / CCAAB experimental area seed planting system. / UFRB. Twenty-five quantitative and qualitative descriptors were applied, nineteen descriptors suggested by the ABPM and six suggested by the NBIO. Descriptive statistical analysis was performed for quantitative characters and the entropy level (H) for quantitative and qualitative characters was analyzed. The entropy level was low for qualitative characters indicating the high homozygous rate in the population. For quantitative traits, the coefficient of variation showed high values demonstrating the influence of the environment on phenotypes, it was also observed that the productivity of the line was affected by fungus (Amphobotrys ricini).
