Abstract

Sorghum L. moench is a Poaceae with morphophysiological characteristics which adapt to water deficiency
conditions, thus becoming a promising alternative for the upper “sertão” region of Sergipe. One way to select
promising sorghum materials in the breeding program is to analyze the correlations between morphological
variables. Thus, the objective of this study was to use the path analysis for indirect selection of forage sorghum based on morphological characteristics in upper Sertão region of Sergipe. The experiment was conducted at Embrapa semiarid experimental farm, in Nossa Senhora da Glória /SE, with an experimental randomized blocks design and three replications. Sixteen genotypes were used, 04 commercial checks and 12 experimental hybrids, totaling 48 plots. The traits studied were: plant height, stem diameter, panicle length, final stand, stem weight, leaf weight, panicle weight, plant weight, fresh matter, dry matter, dry matter percentage, and forage mass. There was variability between the genotypes, and strong and positive phenotypic correlations of plant weight with stem weight, stem diameter, and forage mass from 0.99, 0.92, and 0.78, respectively. The path analysis showed that plant weight had higher positive (0.798) correlation and a high direct effect on the forage mass (0.949). Thus, the indirect selection of sorghum is recommended based on the phenotypical characteristic of greater forage mass through higher plant weight.
