Abstract

The genotype and environment interaction influences the selection criteria of sorghum Sorghum bicolor genotypes. Eight sweet sorghum genotypes were evaluated at five different locations in two growing seasons of 2014. The aim was to determine the interaction between genotype and environment on cane, juice, and ethanol yield and to identify best genotypes for bioethanol production in Kenya. The experiments were conducted in a randomized complete block design replicated three times. Sorghum canes were harvested at hard dough stage of grain development and passed through rollers to obtain juice that was then fermented to obtain ethanol. Cane, juice, and ethanol yield was analyzed using the additive main effect and multiplication interaction model AMMI and genotype plus genotype by environment GGE biplot. The combined analysis of variance of cane and juice yield of sorghum genotypes showed that sweet sorghum genotypes were significantly affected by environments E, genotypes G and genotype by environment interaction GEI. GGE biplot showed high yielding genotypes EUSS10, ACFC003-12, SS14, and EUSS11 for cane yield; EUSS10, EUSS11, and SS14 for juice yield; and EUSS10, SS04, SS14, and ACFC003-12 for ethanol yield. Genotype SS14 showed high general adaptability for cane, juice, and ethanol yield.
