Abstract: El objetivo fue identificar los genotipos de mayor estabilidad en rendimiento de grano, determinar los mejores ambientes y los híbridos con estabilidad en los ambientes. El diseñoexperimental fue Látice Triple Rectangular 5x6. Las variables estudiadas son: rendimiento de grano, altura de planta, altura de mazorca, índice de inserción de mazorca, días a floración masculina y femenina. Se aplicó la metodología de Eberhart y Russell y AMMI (Additive Main Effects and Multiplicative Interaction). La interacción genotipo x ambiente se presentó para todas las variables. El híbrido H21 (31x28) (8.226 t/ha), resultó estable y consistente en las dos metodologías, sin embargo, el modelo AMMI resaltó al hibrido H10 (14x11) (8.372 t/ha) como estable, pero con mayor rendimiento promedio que el hibrido H21 (31x28). El ambiente A2 (Oxapampa-2016) fue el mejor para discriminar el comportamiento de los genotipos en todas las variables según el modelo AMMI, pero también destacaron los ambientes A3 (La Molina-2017) para rendimiento de grano y días a floración masculina y femenina y A1 (La Molina-2016) para altura de planta y altura de mazorca. El análisis de Eberhart-Russell indicó que tienen igual estabilidad los híbridos H12, H13 y H17 para altura de planta, los híbridos H6 y H23 para altura de mazorca, los híbridos H8 y H23 para índice de inserción de mazorca, los híbridos H21, H17 y H25 para días a floración masculina y los híbridos H7 H16 y H17 para días a floración femenina. El modelo AMMI indicó que el híbrido más estable es H28 para altura de planta y altura de mazorca, los híbridos H11 y H28 para índice de inserción de mazorca, el híbrido H21 para días a floración masculina y H24 y H23 para días a floración femenina.
The objective was to identify the genotypes with the greatest stability in grain yield, to determine the best environments and the hybrids with stability in the environments. The experimental design was a 5x6 Rectangular Triple Lattice. The variables studied are: grain yield, plant height, ear height, ear insertion index, days to male and female flowering. The Eberhart-Russell and AMMI (Additive Main Effects and Multiplicative Interaction) methodology was applied. The genotype x environment interaction was presented for all variables. The hybrid H21 (31x28) (8,226 t/ha), was stable and consistent in the two methodologies, however, the AMMI model highlighted the hybrid H10 (14x11) (8,372 t/ha) as stable, but with a higher average yield than the hybrid H21 (31x28). The A2 environment (Oxapampa-2016) was the best to discriminate the behavior of the genotypes in all the variables according to the AMMI model, but the A3 environments (La Molina-2017) also stood out for grain yield and days to male and female flowering. and A1 (La Molina-2016) for plant height and ear height. The Eberhart-Russell analysis indicated that hybrids H12, H13 and H17 for plant height, hybrids H6 and H23 for ear height, hybrids H8 and H23 for ear insertion index, hybrids H21, H17 have equal stability. and H25 for days to male flowering and the hybrids H7 H16 and H17 for days to female flowering. The AMMI model indicated that the most stable hybrid is H28 for plant height and ear height, the hybrids H11 and H28 for ear insertion index, the hybrid H21 for days to male flowering and H24 and H23 for days to female flowering.
