Abstract

This study aimed to select grain sorghum R lines based on grain yield and disease traits. The experiment consisted of 360 experimental R lines and two checks cultivars CMSXS180R and 9503062R. The experimental design used was of augmented blocks. The evaluated characteristics were plant height, days to flowering, thousand-grain mass, grain yield, and evaluation of leaf blight (Exserohilum turcicum) and anthracnose (Colletotrichum graminicola). In the analysis of variance, the interaction between Lines and checks was significant for all characteristics evaluated. All traits showed heritability above 70%, except a thousand-grain mass below 60%. In this work, the lines that obtained the best means were L57 and L74, considered earlier, with plant height ideal for grain and a high grain yield and resistance to foliar diseases.
