- W65414226 abstract "espanolCon el objeto de seleccionar el mejor genotipo, se evaluaron cuatro materiales, en el Ejido Fco. Villa, Municipio de Lerdo, Durango. La siembra se realizo el 23 de agosto de 1996 en surcos separados a 0.8 m y a una distancia entre planta de 0.20 m; se fertilizo con 80 kg de N y17. 48 kg de P ha-1. Se utilizaron dos hibridos (H-412 y H-419) y dos variedades de polinizacion libre, Blanco Hualahuises y San Lorenzo; cada genotipo se sembro en experimentos separados. Se registro el rendimiento de grano de cada genotipo y la humedad acumulada. Se realizaron: un analisis de covarianza entre rendimiento y humedad para conocer la relacion entre las dos variables; un analisis en bloques al azar para rendimiento y se generaron los contrastes pertinentes entre los tratamientos. Se utilizo el analisis de componentes principales como herramienta para discriminar a los genotipos. La relacion entre las variables rendimiento y humedad no fue significativa; el mejor genotipo por rendimiento fue la variedad San Lorenzo y por adaptacion la variedad Blanco Hualahuises. EnglishIn order to select the best genotype, four material were evaluated at the Ejido Francisco Villa, Durango, Municipum allty of Lerdo, Durango, Mexico. The seeding was carried out on august 23 1996, in furrows at 0.8 m and a distance between plants of 0.20 m; it was fertilized with 80 kg N and 17.48 kg P per hectare. Two hybrids (H-412 and H-419), and two varieties of free pollination (Blanco Hualahuises and San Lorenzo) were used; each genotype was seeded apart. Grain yield and soil moisture were recorded for each genotype. There was conducted an analysis of covariance among grain yield and soil moisture to know the relationship between those variables; an analysis of variance according to the randomised complete block design for grain yield and orthogonals contrasts between treatments were generated. An analysis of principals components was used as a tool to discriminate genotypes. The relationship among the variable grain yield and moisture was not significant; the best genotype for grain yield was the variety San Lorenzo and for adaptation the variety San Lorenzo." @default.
