GOMEZ MASJUAN, Yarisbel; BOICET FABRE, Tony; TORNES OLIVERA, Norge  e  MERINO HERNANDEZ, Yanitza. Genotype environment interaction of four tomato varieties in Granma province. Ctro. Agr. [online]. 2018, vol.45, n.2, pp. 21-28. ISSN 0253-5785.

ABSTRACT The investigation was carried out in four localities of Granma province, Cuba. The objective was to evaluate the magnitude of the genotype-environment interactions and adaptation of tomato varieties in different locations affected by drought through performance stability parameters. A combined analysis of variance for the main effects of genotype and environment was performed, and a principal component analysis for non-additive effects of the interaction. This analysis called the Principal Additive Effects and Multiplicative Interaction Model is constituted by additive and multiplicative parameters. It was analyzed by MATMODEL program. Genotype-environment interaction expressed the ability varieties to fit a particular environment. The varieties Amalia and Vyta presented the highest adaptability and the highest yields (30.26 and 24.84 t ha^-1 respectively)
