Abstract

The evaluation of genotypes in different environments is essential to identify superior materials in productivity and agro-industrial quality. This study analyzed sugarcane genotypes in a trial conducted by RIDESA/UFAL in Alagoas, Brazil, during the 2022/23 season. The variables assessed were tons of cane per hectare (TCH), recoverable total sugars (ATR), and tons of ATR per hectare (TATRH), with means compared using the Scott-Knott test (p ≤ 0.05). Considerable variation was observed among genotypes, with RB16517 and RB16521 outperforming commercial standards in TCH and TATRH, leading to higher agro-industrial yields. Statistical analysis and data visualization reinforce the role of experimental evaluation in supporting varietal recommendation decisions in sugarcane breeding programs.
