Con el objetivo de determinar el rendimiento y la resistencia a la roya (Puccinia spp) de líneas avanzadas de trigo (Triticum aestivum L.) introducidas en condiciones de Canchan-Huánuco (2020 m.s.n.m.) se evaluaron en la campaña agrícola 2008 50 líneas en el Ensayo Internacional de Rendimiento (15 SAWYT) empleando el diseño completo aleatorizado con dos repeticiones y 194 líneas en el Vivero Internacional de Selección (25 SAWSN) con una distribución sistemática sin repeticiones. Del primer experimento se seleccionaron ocho líneas promisorias con rendimientos entre 3 163.9 y 6 566.7 kg/ha con respuestas a la roya moderadamente resistente y una severidad igual o menor de 10%. En el segundo ensayo se identificaron 15 líneas superiores, con rendimientos entre 1700 y 4150 kg/ha con adecuados niveles de resistencia a la roya y tipos agronómicos que favorecen el alto rendimiento.

In order to determine the yield and resistance to rust (Puccinia spp) in advanced lines of wheat (Triticum aestivum L.) introduced in terms of Canchan-Huánuco (2020 m) were evaluated in the 2008 season in 50 lines International Yield Trial (15 SAWYT) using completely randomized design with two replications and 194 lines in the International Selection Nursery (25 SAWSN) with a systematic distribution without repetition. The first experiment, we selected eight promising lines with yields between 3163.9 / 6566.7 kg/ha with answers moderately resistant to rust and a severity equal to or less than 10%. In the second trial were 15 lines identified above, with yields between 1700 and 4150 kg/ha with adequate levels of resistance to rust and agronomic rates that encourage high performance.

The objective of this study was to determine the level of yield stability of ten wheat genotypes (Triticum aestivum L.) in five places in Huánuco Region during the crop in 2011, using the design of a randomized complete block. The combined analysis of variance showed highly significant genotype differences for places. In Chaulan (3237 m) was the most favorable environment for the yield of genotypes. Stressed the genotypes ALTAR 84 / AEGILOPS SQUARROSA (TAUS) ..., CHEN / AE. Q / / 2 * OPATA / 3 / BABAX / 4 / JARU and WORRAKATTA / 2 * PASTOR, for showing yields close to 3 000 kg / ha and favorable combinations of parameters bi S2di stability. The national CENTENARIO UNALM showed simultaneous stability and consistency and a performance of 2 835 kg / ha, making it a good indicator of wide adaptability.
